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

What each ingredient does

Grapes
Provide the main fruit flavour and the pulp that forms the body of the preserve.
Sugar
Adds sweetness and, as the mixture cooks down, helps it thicken to a spreadable set.
Oranges
Their juice and skins add acidity and a bright, slightly bitter aroma.
Walnut meats
Add texture and a nutty crunch to the finished preserve.

The step that matters

Cooking time for the set. As water evaporates, the sugar and fruit concentrate and the preserve thickens. Cooking too briefly leaves it runny, while cooking too long can make it stiff and prone to scorching on the bottom.

Swap the orange

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

  1. Figfits better
  2. Vanillafits better
  3. Coconutfits better
  4. Orangethe original

Fit is the average pairing score against sugar, grape, walnut, meat. Candidates are from the same food group and used in at least 100 recipes.
