For this Strawberry Ice Cream you need fresh strawberries, cream, sugar and xanthan gum. It is a Strawberries and Cream ice cream, with enough cream to give it a comforting mouthfeel, yet super-loaded with fresh strawberries to make it burst with strawberry gloriousness.
Xanthan gum is a stabiliser which helps thicken the ice cream mixture, creating a lovely body very close to a store-bought one, which churns beautifully, melts uniformly during serving, and keeps well in the freezer.
Gums -like xanthan gum, carob gum and locust bean gum- are used in ice cream making to stabilise the ice cream mixture. Although you can mix various to make stellar ice cream, the problem is that they can be rather expensive. So instead of buying and storing 2-3 different kinds of gums, you can use only one and still have a terrific ice cream mouthfeel: xanthan gum.
Why xanthan gum? Well, it is the easiest to find online and at the grocery store. It is also the only one which works well on its own (no other gums needed); furthermore, you do not need to apply much heat to it, which means least cooking over the stovetop. And you will never run out of ice cream recipes to use it in: here is a whole collection of ice cream recipes with xanthan gum.

Here are some tricks used in the making of this strawberry ice cream, which take it to the next level.
If you want a beautiful, intense fresh strawberry flavour in your ice cream, there is only one way: cut the strawberries into neat slices and macerate them in sugar for a few hours.
As the strawberries sit in the sugar, the sugar draws out water from the strawberries, creating a strawberry syrup. While the strawberries lie in this syrup, they gradually soften, releasing their strawberry-awesomeness. They end up as the berry-iest version of themselves; sweet, with rounded-up flavours and no acidity.
This way of macerating the strawberries levels up the flavours of any strawberries you use, even the non-seasonal ones.
When using xanthan gum for ice cream making, you need to bring the ice-cream mixture to the right temperature (approx. 52ºC/ 125ºF) before adding the gum. At this temperature, xanthan gum dissolves without clumping, fully hydrates during blending, and effectively stabilises the ice cream mixture.
While it is good to have a thermometer, it is only natural that you may not have one at home. For this reason, I have developed a simple method to bring the mixture to the right temperature without a thermometer before adding the gum. How does it work? Thanks to physics, you can calculate the temperature of a mix of liquids with different temperatures. But to do so, you need two temperatures that you do not need a thermometer to measure. Luckily, there are two temperatures in a modern home which are always the same:
What we do is divide by 50%-50% the blended mixture (milk, cream, sugar) that we want to stabilise with the xanthan gum; half of the blend must be boiling hot and the other half fridge-cold.
When you blend them together, the blended mixture instantly reaches approx. 52ºC/ 125ºF; you then sprinkle the xanthan gum and blend for two minutes to fully hydrate. That works every time, and it is an easy way to use xanthan gum without a thermometer. And fear not for minor differentiations in the above temperatures, as xanthan gum is quite forgiving. In fact 52ºC/ 125ºF is the temperature I prefer for convenience; actually xanthan gum works anywhere between 45ºC-62ºC/ 113ºF-143ºF.
Note: if you live at a high altitude, you can still use this method as xanthan gum is quite forgiving. A minor differentiation in the boiling mixture will not affect the outcome.
Well, the answer is: don’t. Straining removes part of the strawberry pulp along with the seeds. This strawberry pulp is essential in our final ice cream, both for its flavour and the sugars it contains.
So avoid straining; the seeds will go unnoticed anyway, as everyone is too busy devouring this ice cream’s bright strawberry flavour to bother with them.
This is what you will need:
Every ingredient plays a vital role in the recipe. Do not attempt to reduce or replace anything; everything is there for a reason. Look out for these:
This recipe makes 1.2 litre/quart ice cream mixture (before churning), perfect for ice cream makers with a capacity of 1.5 and up to 2 litres/quarts (like Cuisinart ice cream makers). If you need to scale the ice cream mixture up or down , use this ratio of the ingredients (in weight only): strawberries 41.8%, heavy cream 41.8%%, sugar 16.28%, xanthan gum 0.12% in desired total weight of ice cream mixture.
For best results, use a digital kitchen scale and measure the ingredients directly into the utensils, as you proceed with the recipe. Avoid weighing in one utensil and transferring to another, as this causes a small, but important loss of quantity, especially in liquids.
If you have a kitchen scale, weigh the ingredients instead of measuring them by cup; it provides accurate results, very much needed in ice cream making. If you do not have a kitchen scale, follow these guidelines: 1 cup (US) = 237 ml | 1 Tbs. = 15 ml
– Sugar: measuring sugar in tablespoons is more accurate than measuring it in cups. Do not use a regular tablespoon: you need a 15 ml measuring tablespoon; this is 13 gr of sugar. To measure, scoop the sugar to fill the tablespoon, then level it with the flat side of a knife. Repeat scooping and levelling. Do not convert the sugar into cups with the usual “1 cup=200 grams” conversion; this is too much sugar, which results in sloppy ice cream.
– Strawberries: unfortunately, you cannot measure the strawberries in a cup, only by weight.
– Heavy cream: make sure that you thoroughly scrape the cup with a rubber spatula every time you measure something and empty it.
Only use fresh strawberries, preferably juicy, in-season ones. Frozen strawberries will not do.
You can find xanthan gum in speciality shops, health food stores and online. It should contain only xanthan gum and no additional ingredients.
You can adjust the quantity of the xanthan gum in the recipe to your liking, depending on the texture you want to achieve:
Heavy cream: 35-40% fat content is ok. It should be of pourable consistency. “Ultra-pasteurised cream” and “cream suitable for whipping” with 35-40% fat are ok, too. Avoid any cream which contains sugar or other sweeteners. Do not substitute with low-fat cream or plant-based cream.
You can combine double cream with whole milk to make heavy cream for this recipe. To make 500 gr (17.6 oz.) heavy cream, you need:
To make the heavy cream, put the double cream in a medium bowl and pour in the milk, a little at a time, stirring smoothly with a rubber spatula until smooth. Avoid whisking, as it may turn into whipped cream.
The resulting heavy cream has 36% fat, perfect for this ice cream. Proceed with the recipe, just as if you had the 500 gr (17.6 oz.) heavy cream needed.
Only use regular sugar (white granulated sugar).
Do not use a raw cane sugar such as Turbinado or Demerara, they tend to mask the strawberryies’ delicate flavours.
Do not try to reduce the calories of the ice cream by cutting down the sugar or replacing it with low-calories or “healthy” sweeteners. Do not use:
A flexible rubber spatula is good for:
-wiping the bottom of the saucepan when cooking dairy on the stovetop.
-scraping residues from bowls, saucepans etc.
If you do not have one, I strongly encourage you to buy one, preferably a flexible one.
Make the ice cream mixture (steps 1-3) one day before churning it.
If your ice cream maker has a removable freezer bowl, put it in the freezer for the whole time indicated by the manufacturer before churning, usually 24 hours.
Slice the strawberries (500 gr; 17.6 oz.) into 1 cm (0.5 in.) slices with a sharp knife, taking care that you do not smash their flesh,
Mix the strawberries with the sugar: in a large bowl put the strawberry slices and the sugar (195 gr; 6.9 oz.). Stir with a rubber spatula, leaving the spatula in the bowl.
Check for any undissolved sugar on the bottom of the bowl; the strawberries are ready when all the sugar has dissolved; by now, a red syrup, enough to cover the strawberries, will have formed. If there is still any undissolved sugar in the bottom of the bowl, give the sugar a thorough stir to dissolve it and let the strawberries macerate for 15 minutes more.
Separate the strawberries from their syrup: with a slotted spoon, remove the strawberries from the bowl and place them in the blender’s jar. Pour all the syrup into a medium saucepan.
Blend the strawberries until smooth; stop the blender and leave them there while you boil the syrup.
Bring the red syrup to a boil over medium-high (this is at 95°C / 203°F / when large bubbles which pop vigorously appear on the surface).
The moment it comes to a boil, remove it from the heat.
Pour the boiling hot syrup into the strawberries: turn the blender on low speed and start pouring the hot syrup.
Add the xanthan gum and blend: with the blender on, slowly sprinkle the xanthan gum (½ tsp.) over the surface and blend for 2 minutes to fully hydrate the xanthan gum. At this point, do not expect the blend to thicken; this will happen as it cools.
Add the cream: with the blender on, pour the cold cream in the strawberries and blend until a uniform pink colour is obtained. If needed, stop the blender and scrape down its sides with a rubber spatula, then blend again until fully combined.
Cool it down: prepare an ice bath by putting ice cubes and cold water in a large bowl and carefully nest the bowl with the ice cream mixture over it, taking care that no water slips into the ice cream mixture. Let it cool down for 30 minutes, stirring occasionally.
Chill until completely cold: cover the bowl and refrigerate for at least 8 hours or until completely cold; and up to 1 day.
The ice cream mixture will get colder if you store it in a glass container (vs storing it in a plastic one).
If you don’t have a glass container, store the ice cream mixture in the back of the fridge where things are colder.
You want the ice cream mixture to be as cold as possible before you churn it so that it fluffs us to its fullest potential. If you have a thermometer, the perfect temperature of the ice cream mixture to start churning it is at 8°C / 46°F (and anywhere between 4°C-12°C / 39°F-53°F it is ok too!)
When churning with a domestic ice cream maker, your ice cream mixture should always be fridge-cold. Otherwise, if the ice cream mixture is not cold enough, the ice cream maker may not churn it to its fullest potential, resulting in a sloppy liquid vs. fluffy ice cream.
Check the ice cream mixture if it is cold before churning: it should feel fridge-cold to the touch (if you have a thermometer, this is approx. 4ºC–12ºC / 39ºF-53F ).
Stir: this ice cream mixture may become very thick after chilling, so give it a thorough and vigorous stirring with a rubber spatula to loosen it (or a quick blitz with an immersion blender); this will allow it to churn for longer and to acquire a better texture.
If the ice cream mixture is too thick (say, like yoghurt), give it a blitz with an immersion/regular blender before churning it to loosen it.
Why should you do that? If the ice cream mixture is too thick, the ice cream maker may stop before it incorporates enough air into the ice cream. In this case, the ice cream will be sloppy instead of fluffy.
So, if you are after fluffy ice cream, take the time to bring the ice cream mixture to a fluid (pourable) thickness before churning it.
If you feel unsure about the ice cream’s thickness, prefer to err on the side of fluid and give the ice cream mixture a blend nevertheless before churning it.
Churn: with the machine running, pour the ice cream mixture through the canister and into the ice cream maker. Leave to churn until fluffed up and creamy; depending on your ice cream maker this can take anywhere from 30-60 minutes (see below).
This ice cream will expand and fluff up during churning. It is ready when it looks smooth and fluffy. That could take anywhere from 30-60 minutes, depending on your ice cream maker.
To evaluate if it is ready, lift a spoonful; it should be thick enough to stand on the spoon, but it will be still soft like soft-serve ice cream. If you lift ice cream with the spoon and a pool immediately starts forming on its edges, you will have to churn it for longer.
In any case, if you feel doubts about the consistency, leave it to churn for ten minutes more. But beware: at this stage, do not expect it to be like store-bought carton ice cream; for now, it should be more like soft-serve ice cream. It will firm up and become like store-bought ice cream only after it sets in the freezer.
So, stop the ice cream maker when thick and creamy, as described above. If you leave it to churn for much longer, it will start turning grainy.
Warning: some ice cream makers are programmed to automatically stop after a specific length of time, which doesn’t make sense because the ice cream may need to churn for more to reach its fullest potential. So, if you notice that your ice cream maker stops on its own and upon checking the ice cream, you find that it is sloppy instead of fluffy, try to turn the machine on again and leave it to churn until it reaches the desired texture.
Put in the freezer to set: before serving the ice cream or moving it to a container for storing, you have to put it in the freezer to set. To do so, turn off the ice cream machine and:
Setting time depends on the ice cream maker you use; see below for indicative times. Do not leave the freshly churned ice cream in a removable freezer bowl for more than 5-6 hours, or it will become too hard to scoop; if this happens, read the troubleshooting bulb below:
The setting time for the ice cream largely depends on the type of ice cream maker you use.
It can take :
Note: the times given are indicative. Setting time depends on many factors.
Check it occasionally (approx. every 2 hours; or as needed) while it is in the freezer. The ice cream is ready when it has an internal temperature of -11ºC / 12ºF. If you do not have a thermometer, to evaluate if the ice cream has set, insert a round tip knife into it, all the way to the bottom:
If the ice cream stays in the removable freezer bowl for too long, it will harden and be difficult to remove or serve.
To make it scoopable again, leave it in the refrigerator to soften. That can take:
(Note: the time given is indicative, time may vary depending on many factors, so do check it occasionally as it sits in the refrigerator.)
When the ice cream is easy to scoop (or it has an internal temperature of approx. -11°C / 12°F if you have a thermometer), you can transfer it to another container and store it in the freezer or serve it directly from the removable freezer bowl.
Straight after churning, the ice cream has a soft-serve consistency and melts immediately upon contact with anything. This makes it impossible to serve or transfer to another container.
Putting it in the freezer after churning sets it and brings it to the right consistency, similar to that of an ice cream parlour’s.
Serve or store: when it sets, you can either serve it directly from the removable freezer bowl or transfer it to an airtight container for longer storing.
Storing: in the freezer for one month, covered well to protect it from absorbing the freezer’s smells.
Scooping: this ice cream, like all artisanal ice creams, freezes hard in the long term. To soften it to a perfectly scoopable consistency, put it in the refrigerator for 45-60 minutes.
If you have an instant-read (or infrared) thermometer, the perfect serving temperature of this ice cream is when midway through the ice cream the thermometer reads approx. -11ºC / 12ºF. At this the temperature, the ice cream has a lovely mouthfeel and is perfectly scoopable.
