Preserved Barberries

Ingredients

Directions

Cook the barberries

  1. Drop the stemmed barberries into boiling molasses (1 quart of fruit to 1 pint of molasses) or a mixture of half molasses and half sugar.

  2. Boil for 10 to 15 minutes, then skim out the barberries.

Make the syrup and finish

  1. Boil the syrup slowly for an additional 10 to 15 minutes.

  2. If using, pare and quarter the hard sweet apples and add them to the syrup after skimming out the barberries.

  3. Boil the apples until cooked, then return the barberries to the pot.

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

What each ingredient does

Barberries
Provide the tart fruit flavor that the sweet syrup balances.
Molasses
Adds deep sweetness, dark color and a rich, slightly bitter flavor.
Sugar
Adds sweetness and helps the syrup thicken as it boils down.

The step that matters

Skimming out the barberries after the first boil. Fruit left in boiling syrup keeps cooking and can break down into mush. Removing it after 10 to 15 minutes keeps the berries whole while the syrup thickens.

Swap the apple

The recipe marks apple as optional. How well each one fits the dish's main ingredients (lemon, molasses, sugar):

  1. Orangefits better
  2. Raisinfits better
  3. Vanillafits better
  4. Applethe original

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