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

What each ingredient does

Blackberries
Provide the fruit that is preserved and flavored by the syrup.
Sugar
Sweetens the syrup and helps preserve the fruit.
Vinegar
Adds acidity that gives the pickle its tang and helps preserve it.
Cloves
Add warm, aromatic spice flavor to the syrup.
Cassia buds
Add warm, aromatic spice flavor to the syrup.

The step that matters

Reducing the syrup. Boiling the syrup after the fruit is removed concentrates the sugar and vinegar, thickening it so it coats the blackberries well. Under-reducing leaves a thin liquid, while over-boiling can make it too thick or syrupy once cooled.

Swap the cassia

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

  1. Cinnamonfits better
  2. Allspicefits better
  3. Gingerfits better
  4. Cassiathe original

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