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

What each ingredient does

Heavy cream
Provides fat and body, giving the whip its rich, thick texture.
Egg white
Its proteins foam when beaten, adding lightness and airy structure to the whip.
Lemon juice
Adds acidity that brightens the flavor and balances the sweetness.
Sugar
Sweetens the dish and dissolves into the lemon juice.
Castor sugar
Sweetens the cream and dissolves easily into it for a smooth texture.

The step that matters

Pouring the cream over the lemon mixture. Lemon juice is acidic, and acid can thicken or curdle cream. Adding the cream mixture gently and serving right away helps keep the whip smooth and light.

Swap the lemon

How well each one fits the dish's main ingredients (sugar, egg, cream):
