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

What each ingredient does

Boiling apples
Break down into the smooth body of the marmalade.
Butter
Adds richness and a silky texture to the marmalade.
Sugar
Sweetens the marmalade and helps it thicken as it cooks.
Lemon juice
Adds acidity that brightens the sweet apple flavor.

The step that matters

Cooking the marmalade over gentle heat. Apples scorch easily on direct heat, and sugar can burn at high temperatures. Stirring often and keeping the heat low lets the mixture reduce evenly into a smooth, dry marmalade without catching on the pan.

Swap the lemon
