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

What each ingredient does

Vinegar
Provides the acidity that preserves the grapes and gives the pickle its sharp flavour.
White sugar
Balances the sharpness of the vinegar and adds sweetness to the pickling liquid.
Cinnamon
Adds warm, sweet aroma to the pickling liquid.
Cloves
Adds a pungent, warm aroma to the pickling liquid.
Grapes
The main ingredient, which softens slightly and absorbs the flavour of the spiced vinegar brine.

The step that matters

Boil the mixture well, then let it cool. Boiling the vinegar and sugar dissolves the sugar and brings the spices' flavour into the liquid. Pouring the mixture over the grapes while it is still hot would soften them and cook them, so it must cool first.

Swap the grape

The recipe marks grape as optional. How well each one fits the dish's main ingredients (vinegar, sugar, cinnamon, cassia, clove):

  1. Vanillafits better
  2. Figfits better
  3. Applefits better
  4. Grapethe original

Fit is the average pairing score against vinegar, sugar, cinnamon, cassia, clove. Candidates are from the same food group and used in at least 100 recipes.
