Make the ultimate homemade frozen treat by mastering how to make a custard base for ice cream. Plus, my favorite recipe for the best custard base for ice cream, and a recovery hack for if you curdle your base!
Making a custard base for ice cream is a bit time consuming. The results, however, are proof of the work put into it. You get a creamy, dreamy, luxuriously smooth ice cream that begs to be eaten. It calls to you in your dreams, whisks you away to pleasant places during the day, and more than anything, tempts you to make poor choices about portion sizes…
Why Use A Custard Base For Ice Cream?
Custard ice creams give you that classic texture that you think of with ice cream; super smooth, thick, and decadent. Not to mention, custard ice creams don’t get freezer burnt as easily because there is less water particles are smaller and the eggs work as an emulsifier to contain the water.
But if you’re wondering if a custard base is worth your time, the answer really comes down to preference. Many custardless ice creams out there are fantastic. In fact, I did a guest post for Cook.Craft.Love last year on a Strawberry-Lavender Ice Cream (it also comes with a fantastic story about my brief foray into kleptomania) that is extremely delicious despite not having a custard base. So I would say that more than anything, it comes down to what kind of ice cream you’re making.
Custard bases are ideal for when you want a super thick, rich, and decadent ice cream. It’s better suited for the elegant or indulgent flavors that the custard will help bring out; like, vanilla bean, dark chocolate, dulce de leche, salted caramel, or white chocolate. It’s also nice to use a custard base when you’re adding in flavors that have a high amount of water in them – like peach, mango, or lemon.
How To Recover A Curdled Custard Base For Ice Cream
The most important thing to know for making a custard base for ice cream, is that temperature control is key. There is a fine line between a silky custard and scrambled eggs, so make sure you have a well-calibrated thermometer in you pot at all times. As soon as you see the temperature hit 180°F, shut off the heat, and move the pot away from the burner. If you let your custard base site while it’s still on the burner, the residual heat can end up taking your base over that fine line.
“What happens if I scramble the eggs in my custard base?”, you may be thinking. All hope is not lost my friend, I have a recovery hack that works excellently every single time.
To recover a curdled custard base for ice cream: cool the custard to room temperature, place it in a blender and blend on medium-high for 15-30 seconds or until the custard base is once again smooth.
Blending your curdled ice cream base will help break down the egg into teeny-tiny pieces so it won’t effect texture. You may find that the flavor of your ice cream is a bit more “eggy” than if they hadn’t curdled, but 9 times out of 10, no one will notice.
The Best Custard Base For Ice Cream
This is my absolutely favorite way of making a custard base for ice cream. A lot of the recipes on the internet (including the one that I’m putting out later this week) allow for you to just cook the custard base right in the pot. The problem with that is that it doesn’t provide very good temperature control. Using a double boiler gives you more control since the base isn’t directly touching a heat source. It also gives you more ice cream at the end because you don’t lose as much to it sticking to the pot.
If you would like to heat it up in your pot instead of the double boiler, no problem. I do still recommend adding the chilled heavy cream at the end to stop the cooking to make sure your residual heat doesn’t overcook your base.

How To Make A Custard Base For Ice Cream + Best Custard Base Recipe
- 6 egg yolks
- 3/4 cup granulated sugar
- 2 cups whole milk
- 1 cup heavy cream
- 1 tsp salt
- 1 tsp pure vanilla extract (optional)
Combine the egg yolks and sugar in a bowl. Whip the mixture until it becomes thick and the color turns a light yellow.
Scald the milk in a pot, then gradually beat it into the egg mixture. If you add in too much too soon in will scramble your eggs. Take your time.
Stirring constantly, continue to heat over a water bath or double boiler until the mixture thickens enough to coat the back of a spoon. Remove from the heat.
Immediately stir in the cold cream to stop the cooking. Add the salt and vanilla if using.
Chill the mixture for at least 12 hours, then freeze in a ice cream maker according to the manufacturer's directions.
If you are using a container of heavy cream that has previously been opened, make sure to scald and cool it prior to use. This will help reduce the risk of food-borne illness.
