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

What each ingredient does

Egg whites and shells
Egg whites bind and clarify the liquid, collecting impurities that are then strained away, leaving it clear.
Sheet gelatine
Gelatine forms the gel structure that makes the jelly set firm once chilled.
Loaf sugar
Sugar adds sweetness and helps give the jelly its body and clear texture.
Lemon juice
Lemon juice provides the main acidity and bright lemon flavour.

The step that matters

Strain through a clean, scalded cloth. Straining removes the egg white and solids that clouded the liquid. If the cloth is not clean and scalded, the jelly can stay cloudy or pick up off-flavours.

Swap the lemon

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