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

What each ingredient does

Pears
Provide the bulk of the fruit pulp and mild, fresh sweetness.
Quinces
Add natural pectin, helping the marmalade set as it cools.
Brown sugar
Sweetens the fruit and, as it cooks down, helps thicken it into a preserve.

The step that matters

Adding the sugar after the fruit has softened. Sugar added to firm fruit slows its softening and can leave it tough. Once the fruit is soft, sugar dissolves easily and concentrates as water evaporates. Constant stirring keeps it from sticking and scorching on the base of the pan.

Swap the quince
