THE FRENCH-STYLE ICE CREAM

Chocolate-only Ice Cream
• with egg yolks •

(aka custard-based)

With chocolate, milk, heavy cream, sugar, and egg yolks.

This Chocolate-only ice cream is perfect for celebrating the flavour of your favourite chocolate bar. It is also lower in cocoa than our rich Classic Chocolate Ice Cream -made with chocolate AND cocoa powder- so if you like your chocolate ice cream lighter in chocolate flavour this is the perfect ice cream for you. Children love it this way, too!

A French-style ice cream contains egg yolks cooked with milk over the stovetop to make a custard. Making a custard is a little tricky but worth the effort for the velvety ice cream it creates.

Overview

This is a quick overview of the recipe. If you are new to ice cream making, do read the recipe before proceeding. 

The recipe
Chocolate-only Ice Cream | with egg yolks
Ingredients:
Notes:

When making ice cream, prefer to weigh all the ingredients, even the liquid ones. We also recommend – whenever possible – to weigh the liquid ingredients directly into the bowl/pan as you proceed with the recipe instead of transferring them from one bowl to another because this transfer causes a small -but unwanted- loss of quantity.

If you do not have a kitchen scale, follow these guidelines:

• 1 cup (US) = 237 ml | 1 tablespoon = 15 ml

• sugar: measuring sugar in tablespoons is more accurate than measuring it in cups. Use a 15 ml measuring tablespoon (not a regular one); this is 13 gr of sugar. To measure correctly, each time you scoop the sugar, level it with the flat side of a knife.

• chocolate/couverture: measuring chocolate in cups is not possible because measurements vary depending on how finely chopped the chocolate is. Instead, you can estimate the number of chocolate pieces you need based on the weight of the chocolate bar as written on the packaging.

• milk and heavy cream: thoroughly scrape with a rubber spatula any residues left on the sides and bottom of the cup every time you measure something and empty it.

Note that the quantities in each measuring system (grams, ounces, and cups) in our recipes may not always be accurate conversions; any deviations in conversions you may notice do not affect the outcome.

This recipe makes a 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): 

milk 39.4% / heavy cream 29.5% / sugar 14.1 % / 70-74% cocoa solids chocolate 10.4% / egg yolks 6.6%

in desired total weight of ice cream mixture.

For example, if you want to make 1000 g (approx. 1 litre) of ice cream mixture, you need:

• 1000 g x 39.4% = 394 g milk

• 1000 g x 29.5% = 295 g heavy cream

• 1000 g x 14.1% = 141 g sugar

• 1000 g x 10.4% = 104 g chocolate 70-74%

• 1000 g x 6.6% = 66 g egg yolks

You can combine double cream with whole milk to make heavy cream for this recipe.

To make 355 g (12.5 oz) heavy cream, stir together:

  • 250 g double cream (8.8 oz) (with approx. 50% fat)
  • 105 g / ml whole milk (3.7 oz) (with approx. 3.5% fat) -note that this milk is extra to the 475 g; 16.8 oz asked in the recipe-

The resulting heavy cream has 36% fat, perfect for this ice cream. Proceed with the recipe just as if you had the 355 g (12.5 oz) heavy cream needed. 

A flexible rubber spatula is good for:
-wiping the bottom of the saucepan when you cook dairy on the stovetop.
-scraping residues from bowls, saucepans etc.

If you do not have one, we strongly encourage you to buy one, preferably a flexible one. 

Instructions
Plan ahead:

The ice cream mixture needs to cool completely before churning, so prepare it in advance (approx. 8 hours before) to give it time to chill in the refrigerator. 

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.

Step 1: Make the ice cream mixture

Place a rubber spatula and a whisk on a plate next to the stovetop to have them ready to use interchangeably.

Prepare the chocolateplace the chopped chocolate into a large heatproof bowl and set the bowl near the stovetop.

Prepare the egg yolks: put the egg yolks (4 egg yolks) in a medium heatproof bowl, and whisk them lightly to break them down; set the bowl near the stovetop.

Warm the milk and the sugar: place the milk (475 g; 16.8 oz) and the sugar in a medium saucepan. Warm over medium heat, often stirring, until the sugar dissolves.

Temper the egg yolks: when all the sugar dissolves and the milk is hot and steamy (this is at 75ºC / 167 ºF, if you have a thermometer), remove the saucepan from the heat and slowly ladle roughly half of the warm milk over the egg yolks with one hand while whisking them vigorously with the other hand to temper them.

Cook until thickened: pour the tempered yolks & milk back into the saucepan and over medium-high heat. Cook, constantly stirring with a rubber spatula and scraping the bottom of the saucepan to prevent the custard from scalding. Maintain a medium temperature, do not let it come to a boil. 

Remove from the heat when the custard starts to thicken (82ºC / 179 ºF / when it thickens to coat the back of a spoon / 

when you tilt the saucepan, a layer of thickened custard appears to form on the bottom).

Pour the custard over the chopped chocolate. Let it sit for 1 minute.

Whisk to melt the chocolate, scraping with the rubber spatula the insides of the bowl as needed.

Add the heavy cream (355 g; 12.5 oz) and stir to combine.

Blend with an immersion/regular blender until it is a uniform brown colour with no streaks, pausing to scrape the bottom and sides of the saucepan/blender jug with the rubber spatula as needed.

Step 2: Chill in the fridge overnight.

Cool it down: prepare an ice bath by putting the bowl with the ice cream mixture into a larger bowl and filling the empty sides with ice cubes and cold water. How many ice cubes? You will need two trays of ice cubes (approx. 400 g; 14 oz of ice) to bring the ice cream mixture to room temperature. Let the ice cream mixture cool down for 30 minutes, stirring occasionally.

Chill until completely cold: cover the bowl and refrigerate for at least 8 hours and up to 3 days. This time is also necessary for a custard-based ice cream to mature and its flavours to develop, so do not rush the cooling process.

Step 3: Churn the ice cream

Check if the ice cream mixture is cold before churning it: 4ºC–12ºC / 39ºF-54ºF / it feels fridge-cold when you place your finger into it.

Prepare the ice cream maker according to the manufacturer’s instructions. 

Blend before churning: briefly blitz the ice cream mixture with an immersion blender, stopping once to scrape down the sides and bottom with a rubber spatula. This improves consistency and ensures a smooth, even texture.

Churn: with the machine running, pour the ice cream mixture through the canister and into the ice cream makerLeave to churn until fluffed up and creamy; depending on your ice cream maker, this can take anywhere from 30-60 minutes.

This ice cream mixture expands and becomes airy as it churns. You’ll know it’s ready when it looks smooth, creamy, and slightly wavy—similar to soft-serve ice cream. Churning time varies depending on your machine and can take anywhere from 30 to 70 minutes.

To check the texture, lift a spoonful. It should be thick enough to stay on the spoon, but still soft. If it looks too thin or starts melting immediately, it needs more time.

If you’re unsure, let it churn for 10 more minutes. Keep in mind that it won’t look like store-bought ice cream at this point—it will still be soft. It only becomes firm and scoopable after a few hours in the freezer.

Stop the machine once the mixture is thick and creamy. If you continue churning beyond that point, the mixture can start losing the air it has built up and may seize, resulting in a dense, heavy texture.

One important note: some ice cream makers are programmed to stop automatically after a fixed time, but that doesn’t always mean the ice cream is ready. If your machine stops and the mixture still looks too soft, simply restart it and continue churning until the texture improves.


 

Step 4: Put the ice cream in the freezer to set
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 maker and: 
· remove the removable freezer bowl (still filled with the ice cream) from the ice cream machine
· remove the paddle, scraping any ice cream attached to it back into the ice cream bowl 
· cover the ice cream bowl and place it in the freezer 
Setting time depends on many factors; see notes below for indicative times.

Serve or store: when it sets, you can serve it directly from the removable freezer bowl or transfer it to an airtight container for longer storage.

The setting time depends on the type of ice cream maker you’re using. Here are the general guidelines:

3–5 hours for machines with removable freezer bowls (these bowls must be pre-frozen before churning)

Under 1 hour for machines with built-in compressors and aluminum bowls
⚠️ Important: Ice cream in aluminum bowls sets quickly. Do not leave it for too long—once fully frozen, it can become extremely hard and difficult to remove without risking scratches to the bowl. Always monitor it closely.

To check if the ice cream is ready, aim for an internal temperature of –11°C (12°F). If you don’t have a thermometer, use this simple test:

Insert a round-tip knife all the way to the bottom of the ice cream:
✔ If it goes in smoothly but meets gentle resistance, it’s ready
✖ If it feels hard on top but soft underneath, it needs more time
✖ If it’s too firm to insert the knife, it’s over-frozen and likely too hard to scoop

If it’s over-frozen, don’t worry—head to the next section for how to bring it back to scoopable.

If the ice cream sits in the freezer in the removable freezer bowl for too long after it has set, it can become too hard to scoop or remove.

To make it scoopable again:
Place the bowl in the refrigerator and allow the ice cream to soften gradually.

Here’s how long that may take:

4–10 hours for removable freezer bowls (pre-freeze models)

1–2 hours for aluminum bowls (from compressor ice cream makers)

Note: These times are approximate and may vary depending on your fridge and the amount of ice cream. Check the texture occasionally as it softens.

Once the ice cream is soft enough to scoop—or its internal temperature reads approximately –11°C (12°F)—you can:

✔ Transfer it to another container and store it in the freezer
✔ Or serve it directly from the bowl

Just be sure to avoid digging into an over-frozen bowl with hard utensils, especially if using a nonstick-coated or aluminum bowl.

Straight after churning, the ice cream has a soft-serve consistency and melts almost instantly on contact. At this stage, it’s too soft to serve neatly or transfer easily—it’s simply too messy to handle.

Freezing the ice cream immediately after churning allows it to set properly. This step brings it to the right texture: scoopable, stable, and easy to portion or transfer into a storage container.

It’s the final step that turns churned ice cream into finished ice cream.

Storing and serving

Storing: Transfer the finished ice cream to a lidded container and store it in the freezer for up to one month.
Cover it well to protect it from absorbing any unwanted freezer smells.

Scooping: Like all artisanal-style ice creams, this one freezes hard over time.
To make it scoopable again, place the container in the refrigerator for 45–60 minutes, or until the internal temperature reaches about –11°C (12°F).
Once softened, it’ll scoop cleanly and serve beautifully.
