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

What each ingredient does

Crab apples
Their natural pectin and acid help the juice set into a firm jelly.
Sugar
Adds sweetness and helps the jelly set and keep its texture.

The step that matters

Boiling to the jelly stage. Boiling must go long enough to concentrate the sugar and pectin so the juice gels. Too little boiling leaves a runny syrup, while overboiling can make the jelly stiff or cloudy.

Swap the apple

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