Why it works: Vinegar and mustard are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 14,067 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Quince Marmalade
Ingredients
Directions
Prepare the fruit
Wash and cut the quinces into small pieces, coring but not paring them.
Combine three-quarters of a pound of sugar and a teacup of water with a pound of fruit.
Cook
Boil slowly for two hours, stirring and mashing it fine.
Strain and serve
Strain through a colander, and put the mixture in glasses or bowls.
Peaches, crab apples or sour apples may be used in the same way.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sugar
- Adds sweetness and, as it concentrates during the long simmer, helps the marmalade set.
- Fruit
- Provides the bulk, flavor and natural pectin that gives the marmalade its body.
The step that matters
Boiling slowly for two hours while stirring. A long, gentle simmer lets water evaporate and the sugar and fruit pectin thicken the mixture. Stirring prevents sticking and scorching on the bottom of the pan, which would give a burnt taste.
Swap the mustard
How well each one fits the dish's main ingredients (sugar, vinegar, pepper):
- Capsicumfits better
- Mustardthe original
- Cabbagefits less well
- Cucumberfits less well
Fit is the average pairing score against sugar, vinegar, pepper. Candidates are from the same food group and used in at least 100 recipes.
