The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks thicken the custard as they gently set with heat.
- Lemon juice
- Adds sharp acidity that balances the sweetness of the custard.
- Lemon rinds
- Lemon oils in the grated rind add bright aroma.
- Rich wine
- Adds liquid and deepens the flavor of the custard.
- Brandy
- Adds aroma and a warm, boozy depth of flavor.
The step that matters
Stirring over heat until thickened. Egg yolks thicken through gentle heating, but if they get too hot they curdle and turn grainy. Keep the heat low and stir constantly so the custard thickens smoothly.
Swap the lemon
How well each one fits the dish's main ingredients (egg, wine, brandy):
- Currantfits better
- Apricotfits better
- Grapefits better
- Lemonthe original
Fit is the average pairing score against egg, wine, brandy. Candidates are from the same food group and used in at least 100 recipes.
