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

What each ingredient does

Eggs
Thicken the mixture as they cook and set it into a creamy, spreadable texture.
Butter
Adds richness and a smooth, silky mouthfeel to the preserve.
Powdered white sugar
Sweetens the preserve and helps give it a smooth, spreadable body.
Lemons
Provide the bright acidity and fragrant oils from the rind that define the flavor.

The step that matters

Cook over low heat until thickened. Eggs can scramble if heated too fast. Gentle, low heat lets the proteins thicken the mixture smoothly into a custard-like cream.
