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

What each ingredient does

Gelatine
Sets the liquid into a firm, sliceable jelly as it cools.
Whole milk
Forms the creamy base and gives the jelly its body and softness.
Eggs
Add richness and help thicken the mixture into a smooth custard-like base.
Loaf sugar
Sweetens the jelly and balances the sharpness of the lemon.
Lemons
Add acidity and bright lemon aroma from the rind and juice.

The step that matters

Strain the hot milk over the eggs and sugar. Pouring hot milk into the eggs too quickly can scramble them. Pour slowly while whisking constantly, so the eggs warm gradually and the mixture stays smooth.

Swap the lemon
