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

What each ingredient does

Pears
Form the fruit base that softens into tender pieces during slow cooking.
Preserving sugar
Adds sweetness and draws liquid from the fruit to form a syrup that helps preserve it.
Lemon
Adds acidity and brightness that balance the sweetness of the sugar and fruit.
Ginger
Adds a warm, aromatic flavor to the pears and syrup.

The step that matters

Cook slowly until the pears are quite tender. Gentle, even heat in the water bath softens the pears through without breaking them apart. Rapid boiling inside the jar can crack the fruit and make the texture uneven.

Swap the pear

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