Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Milk
- Forms the liquid base that the eggs thicken into a custard.
- Eggs
- Set when heated gently, thickening the milk into a custard texture.
- Cooked fish
- Provides the main protein and flaky texture throughout the custard.
- Butter
- Adds fat for richness and a softer mouthfeel in the custard.
The step that matters
Stir in the eggs over low heat. Egg proteins set gently at moderate temperatures. High heat or boiling makes them tighten too fast, causing curdling and a grainy texture. Low heat with constant stirring gives a smooth, thickened custard.
