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.

Milk and sugar barely smell alike, yet cooks put them together in 77,875 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
- Milk
- Forms the liquid base of the custard, giving it body and a creamy texture.
- Grated chocolate
- Adds chocolate flavour and colour to the milk.
- Egg whites
- Whipped into a stiff foam that gives the topping its light, airy texture.
- Sugar
- Sweetens the dish and helps stabilise the beaten egg whites.
The step that matters
Beating the egg whites until stiff. Egg white proteins trap air as they whip. If they are under-beaten the foam will slump on the custard, and if over-beaten they turn dry and grainy. Stop when the peaks stand upright.
Swap the grape
How well each one fits the dish's main ingredients (chocolate, milk, egg, sugar):
- Vanillafits better
- Coconutfits better
- Figfits better
- Grapethe original
Fit is the average pairing score against chocolate, milk, egg, sugar. Candidates are from the same food group and used in at least 100 recipes.
