Why it works: Rice and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 7,374 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓
Rock Cream
Ingredients
Directions
Prepare the rice
Boil the rice in sweet milk until soft.
Sweeten the rice with powdered sugar and pile it high on a dish.
Top and serve
Add square pieces of currant jelly or preserved fruit on top.
Beat the egg whites until stiff, adding powdered sugar and flavoring with orange‑flower water or vanilla.
Add the cream and drop the mixture over the rice to resemble a rock covered with snow.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rice
- Softens in milk to form the pudding base that holds the dish's shape.
- Egg whites
- Whipped into stiff foam that forms the light, snow-like topping.
- Sweet milk
- Cooks the rice until tender and adds creamy moisture to the base.
- Currant jelly or preserved fruit
- Adds sweetness and fruity acidity contrasting with the mild rice.
The step that matters
Beat the egg whites until stiff. Egg whites must be beaten until they hold firm peaks, because the foam traps air and sets the light snow-like texture; under-beaten whites will slump, and any trace of fat or yolk prevents them from stiffening.
Swap the currant
How well each one fits the dish's main ingredients (rice, milk, sugar, egg, cream, orange):
- Vanillafits better
- Coconutfits better
- Lemonfits better
- Currantthe original
Fit is the average pairing score against rice, milk, sugar, egg, cream, orange. Candidates are from the same food group and used in at least 100 recipes.
