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

What each ingredient does

Apples
Provide body and natural pectin that helps the marmalade set.
Pears
Add mild sweetness and soft texture to the mashed fruit.
Peaches
Contribute fruity aroma and softness to the finished spread.
Quinces
Supply pectin and a firm, fragrant character that helps the marmalade set.
Sugar
Sweetens the fruit and, with long cooking, thickens it into a spreadable marmalade.

The step that matters

Cooking the mashed fruit with sugar. Sugar must be added to fruit that is already fully softened, and cooked slowly so it dissolves evenly. Sugar and pectin together help the mixture thicken as water evaporates, and rushing or overheating can scorch the sugar or leave the set uneven.

Swap the peach

How well each one fits the dish's main ingredients (apple, pear, quince, sugar):
