Why it works: Milk and vanilla are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 19,187 recipes. Both carry ethyl caproate, which smells fruity, apple peel. The science ↓
Jelly Custards and Cake
Ingredients
Directions
Make the custard
Heat the milk in a saucepan.
In a bowl, beat the eggs and sugar together.
Pour the hot milk over the egg mixture and stir well.
Return the mixture to the heat and stir until it begins to thicken.
Remove from heat and let it cool, then add flavoring.
Assemble and serve
Pour the custard into cups, filling them nearly to the top.
Top each custard with a slice of firm, bright jelly.
Serve with cake.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Thicken the custard as they set when gently heated, giving it body.
- Milk
- Forms the liquid base of the custard, giving it its creamy body.
- Sugar
- Sweetens the custard and helps soften the set texture of the eggs.
- Crab-apple and currant jelly
- Adds tart, fruity flavor and a bright contrast to the rich custard.
The step that matters
Return the mixture to the heat and stir until it begins to thicken.. Egg proteins set as they warm, so heating gently while stirring thickens the custard smoothly. Overheating can curdle the eggs into lumps.
Swap the currant
How well each one fits the dish's main ingredients (milk, egg, sugar, vanilla, crab, apple):
- Pearfits better
- Figfits better
- Peachfits better
- Currantthe original
Fit is the average pairing score against milk, egg, sugar, vanilla, crab, apple. Candidates are from the same food group and used in at least 100 recipes.
