Custard, Boiled

Why it works: Milk and vanilla are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 19,187 recipes. Both carry ethyl caproate, which smells fruity, apple peel. The science ↓

Custard, Boiled

Ingredients

Directions

Prepare

  1. Rinse a saucepan with cold water to prevent sticking.

  2. Add the milk and flavoring ingredient. Simmer gently until flavored.

  3. Stir in the sugar.

Make the custard

  1. Strain the mixture onto the egg yolks, stirring continuously.

  2. Return the mixture to the saucepan. Stir over low heat until thickened.

  3. Pour the mixture into a jug or double boiler. Place the jug or double boiler in boiling water.

  4. Stir until it coats the spoon.

  5. Add the cream. Stir for 2-3 minutes to cook the cream.

Cool and serve

  1. Let the custard cool. Stir frequently.

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

What each ingredient does

Egg yolks
Thicken the custard as they set when gently heated, giving it body.
Milk
Forms the liquid base that the yolks thicken into a smooth custard.
Caster sugar
Sweetens the custard and adjusts its flavor to taste.
Thick cream
Adds richness and a smoother, fuller mouthfeel to the custard.

The step that matters

Stir over low heat until thickened. Egg yolks set at low temperatures, but high heat or no stirring can overcook them and cause curdling. Gentle, constant stirring keeps the custard smooth.

Swap the lemon

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

  1. Strawberryfits better
  2. Figfits better
  3. Coconutfits better
  4. Lemonthe original

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