Grape Catsup

Ingredients

Directions

Prepare the grapes

  1. Carefully pick over the grapes and place them in a porcelain kettle with enough water to prevent burning.

  2. Boil the grapes until the pulp is dissolved, stirring frequently.

  3. Once the pulp is soft, strain it through a colander and return it to the kettle.

Season and thicken

  1. Add the sugar, vinegar, cinnamon, cloves, allspice, pepper, and salt.

  2. Boil the mixture until it thickens slightly, stirring constantly.

Bottle

  1. Set aside to cool, then bottle and seal.

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

What each ingredient does

Grapes
Provide the fruit pulp that forms the body and base flavor of the catsup.
Sugar
Adds sweetness and, as it dissolves and boils down, helps thicken the catsup.
Vinegar
Adds acidity that sharpens the flavor and helps preserve the catsup.
Ground cinnamon
Contributes warm, aromatic spice flavor.
Ground cloves
Contributes strong, aromatic spice flavor.

The step that matters

Boil the mixture until it thickens slightly, stirring constantly. Sugar and pulp thicken as water evaporates during boiling. Constant stirring prevents scorching on the bottom of the kettle, which would give a burnt taste.

Swap the grape

How well each one fits the dish's main ingredients (sugar, vinegar, cinnamon, clove, allspice, pepper):

  1. Limefits better
  2. Orangefits better
  3. Lemonfits better
  4. Grapethe original

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