The flavor team

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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

What each ingredient does

Blue plums
Provide the fruit that absorbs the sweet, spiced, acidic liquid and becomes tender.
Sugar
Adds sweetness and helps preserve the fruit in the syrup.
Vinegar
Adds sharp acidity that flavours the fruit and helps preserve it.
Cinnamon
Adds warm aroma and spice flavour to the syrup and fruit.

The step that matters

Reboiling the liquid each morning. Boiling the liquid again each morning keeps it hot enough to dissolve sugar and carry flavour into the fruit. Skipping a boil or a day weakens how well the plums take up the syrup.

Swap the plum

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

  1. Vanillafits better
  2. Raisinfits about as well
  3. Figfits about as well
  4. Plumthe original

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