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 pulp and flavor that form the body of the ketchup.
- Sugar
- Adds sweetness and helps thicken and preserve the ketchup.
- Vinegar
- Adds acidity that sharpens flavor and helps preserve the ketchup.
- Cinnamon
- Adds warm aroma and spice flavor.
- Cloves
- Adds strong aromatic spice flavor.
The step that matters
Boil the mixture until it thickens. Boiling drives off water and concentrates the sugar and fruit pulp, which thickens the ketchup. Stopping too early leaves it thin and watery, while boiling too long can scorch the sugars and make it overly dark and sticky.
Swap the grape
How well each one fits the dish's main ingredients (sugar, vinegar, cinnamon, clove, allspice, pepper):
- Limefits better
- Orangefits better
- Lemonfits better
- 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.
