This low-carb sugar-free custard sauce recipe is the traditional way to use up the egg yolks left while making snow pudding and make a sauce for it at the same time.

This sauce is very similar to French crème anglaise, which is a classic dessert sauce that can be used on fruit, or even cake.  

It's not difficult to make, but follow the directions carefully, or you may end up with scrambled eggs!


  • 3/4 cup whole milk and 1/4 cup heavy cream or 1 cup whole milk and no cream
  • 1/4 teaspoon good-quality vanilla
  • Artificial sweetener to equal 2 tablespoons sugar
  • 1/8 teaspoon salt
  • 3 large room-temperature egg yolks


  1. In a small heavy-bottomed saucepan, heat 3/4 cup whole milk and 1/4 cup heavy cream or just 1 cup whole milk (eliminating the cream) until scalding. If it's steaming, it's probably there. Remove from heat. Optionally, you can do this in the microwave as I do.
  2. Add 1/4 teaspoon good-quality vanilla, artificial sweetener to equal 2 tablespoons sugar, and 1/8 teaspoon salt to the milk. Stir well.
  3. In a small, heatproof or stainless-steel bowl, beat 3 large room-temperature egg yolks. Add a little of the hot milk-cream and mix well (this is called "tempering" the eggs so they don't cook).
  1. Repeat, adding a little more milk so you gradually bring the eggs up to temperature.
  2. Put a small amount of water in the bottom of a double boiler or a pot on which you can put the bowl containing the tempered eggs. Heat the water. The water should not be able to touch the bottom of the bowl.
  3. Place the bowl with the tempered eggs over the pot with simmering water and stir or whisk until mixture begins to thicken, then remove from heat and stir until it coats a spoon. Refrigerate.

Nutritional Analysis: Each of 8 servings (2 to 3 tablespoons) has 1.5 grams of carb and 60 calories (less if you don't use the cream).
