Boiled Custard

Ingredients

Directions

Prepare the base

  1. Scald the milk in a double boiler.

  2. In a bowl, beat the egg yolks, sugar, and salt together.

  3. Slowly pour the hot milk into the egg mixture while stirring continuously.

Cook and finish

  1. Return the mixture to the double boiler and cook until it thickens like cream or coats the back of a spoon.

  2. Remove from the stove immediately to prevent curdling.

  3. Strain through a fine strainer and add your chosen flavor.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Milk
Forms the liquid base that the custard thickens into.
Egg yolks
Thicken the custard as they set with gentle heat, adding richness.
Sugar
Sweetens the custard and balances the richness of the yolks.

The step that matters

Remove from the stove immediately once thickened. Egg proteins set with heat, and past the thickened point they tighten and curdle. Taking the custard off the heat as soon as it coats a spoon keeps it smooth.

Swap the nutmeg

How well each one fits the dish's main ingredients (milk, egg, sugar):

  1. Cinnamonfits better
  2. Nutmegthe original
  3. Gingerfits less well
  4. Allspicefits less well

Fit is the average pairing score against milk, egg, sugar. Candidates are from the same food group and used in at least 100 recipes.
