Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Rice
Cooked until soft, it forms the thick base that the topping sits on.
Egg whites
Beaten to a stiff froth, they give the topping its light, airy structure.
Powdered sugar
Dissolves easily into the beaten whites, sweetening and helping stabilize the foam.
Loaf sugar
Sweetens the rice base so it tastes lightly sweet beneath the topping.
Rich cream
Adds moisture and richness to the topping, softening its texture.

The step that matters

Beat the egg whites with powdered sugar to a stiff froth.. Egg whites must be beaten until they hold stiff peaks; under-beaten whites collapse and make the topping heavy, while over-beaten whites turn dry and grainy. Adding the sugar gradually helps the foam stay stable.
