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 ↓
Rock Cream
Ingredients
Directions
Make the rice base
Boil the rice in new milk until quite soft.
Sweeten the rice with powdered sugar.
Transfer the rice to a dish and top with lumps of currant jelly or preserves.
Make the topping and serve
Beat the egg whites to a stiff froth.
Add flavoring and thick cream to the egg whites.
Drop the mixture over the rice to form a 'rock' of cream.

Sugar and vanilla barely smell alike, yet cooks put them together in 35,032 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
- Rice
- Cooks in milk to a soft, thick base that holds the topping.
- Egg whites
- Beaten to a stiff froth, they give the light, airy structure of the rock.
- New milk
- Softens the rice as it boils, giving the base a creamy texture.
- Powdered loaf sugar
- Dissolves easily into the rice, sweetening the base.
- Thick cream
- Adds richness and moisture to the beaten whites.
The step that matters
Beating the egg whites to a stiff froth. Egg whites must be whipped until they hold stiff peaks; under-beaten whites collapse and fail to hold the rock shape, while over-beaten whites turn dry and grainy.
Swap the currant
How well each one fits the dish's main ingredients (rice, milk, sugar, egg, cream, vanilla):

Fit is the average pairing score against rice, milk, sugar, egg, cream, vanilla. Candidates are from the same food group and used in at least 100 recipes.
