Why it works: Egg and milk are a kitchen classic. They rank in the top 18% of all ingredient pairs, and cooks put them together in 88,785 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓

Ingredients
Directions
Prepare the shells
Bake two sponge cakes in round deep patty pans and let them cool.
Cut out the inside of the cakes, leaving a shell about ¼ inch thick.
Fill and top
Beat the egg yolks and mix with boiling milk, sugar, and flavoring.
Pour the custard into the cake shells.
Spread jelly or jam on top of the custard.
Beat the egg whites with powdered sugar and flavoring until stiff peaks form.
Spread the meringue over the jelly.
Chill in a cold place until ready to serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sponge cakes
- Form the edible shell that holds the custard and toppings.
- Egg yolks
- Thicken the milk into a custard through heat-set proteins.
- Egg whites
- Whip into a stiff foam that forms the meringue topping.
- Powdered sugar
- Sweetens the meringue and helps it stay stable when whipped.
- Jelly or jam
- Adds fruity sweetness and a layer between custard and meringue.
The step that matters
Beat the egg whites until stiff peaks form. Egg whites under-whipped stay runny and won't hold the meringue on top, while over-whipped whites turn grainy and collapse. Stiff peaks that stand upright and look glossy give a stable topping.
