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

What each ingredient does

Egg yolks
Proteins thicken the mixture as they gently heat, giving the cream its body and set.
Lemons
Juice supplies sharp acidity and the peel adds fragrant lemon aroma.
Powdered sugar
Dissolves easily into the juice, adding sweetness that balances the lemon's acidity.

The step that matters

Heating the mixture over low heat. Egg yolk proteins set when heated, but too much heat or boiling makes them curdle and turn grainy. Gentle, constant stirring keeps the custard smooth and thick.

Swap the lemon

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