Why it works: Cream and sugar are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 43,450 recipes. Both carry 2,3-butanedione, which smells butter, sweet. The science ↓
Bich Boiled Custard
Ingredients
Directions
Make the custard
Take ½ cup of cream from 1 quart and simmer it with 4 ounces of sugar and the rind of 1 lemon for a few minutes.
Beat and strain the yolks of 8 eggs, then mix them with the ½ cup of cream.
Stir the simmered cream into the egg mixture and thicken the custard over low heat until it coats the back of a spoon.
For the second custard, pour 1½ cups of boiling cream over the beaten yolks of 12 eggs, sweetened with 3 ounces of sugar.
Add a pinch of salt and thicken the custard as usual.
Flavor and finish
When nearly cold, flavor with 1½ wineglassfuls of noyau, maraschino, or cuirasseau, and add almonds if desired.

Sugar and lemon barely smell alike, yet cooks put them together in 53,532 recipes: they work on texture and structure more than aroma.
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 with gentle heat, giving it body and richness.
- Fresh cream
- Adds richness and a smooth, velvety texture to the custard.
- Sugar
- Sweetens the custard and balances the richness of the yolks and cream.
- Lemon rind
- Infuses the simmered cream with citrus aroma.
The step that matters
Thicken the custard over low heat. Egg yolk proteins set gradually; too much heat scrambles them into curds, so stir constantly and stop once the custard coats a spoon.
Swap the almond
The recipe marks almond as optional. How well each one fits the dish's main ingredients (cream, sugar, lemon, egg):
- Pistachiofits about as well
- Almondthe original
- Chestnutfits about as well
- Walnutfits less well
Fit is the average pairing score against cream, sugar, lemon, egg. Candidates are from the same food group and used in at least 100 recipes.
