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 ↓
Crkam Custard
Ingredients
Directions
Make the custard
Whip the egg whites and sugar until stiff and frothy.
Bring the cream to a boil, then remove from heat.
Quickly stir in the whipped egg mixture.
Allow the mixture to just begin to boil, then pour into a bowl, stirring lightly a couple of times.
Finish and serve
Once cooled, pour into a glass dish and season with Virot's Lemon or Vanilla Extract.

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 whites
- Whipped to foam, they give the custard its light, airy structure.
- Cream
- Provides fat and richness, giving the custard a smooth, creamy texture.
- Pounded loaf sugar
- Whipped with the egg whites to stabilise the foam and add sweetness.
The step that matters
Allow the mixture to just begin to boil. Egg proteins set with heat, so the mixture should only just begin to boil. Overheating can curdle the eggs and make the custard grainy instead of smooth.
Swap the lemon
How well each one fits the dish's main ingredients (cream, egg, sugar):
- Vanillafits better
- Raisinfits better
- Strawberryfits about as well
- Lemonthe original
Fit is the average pairing score against cream, egg, sugar. Candidates are from the same food group and used in at least 100 recipes.
