Plum Butter

Ingredients

Directions

Prepare the plums

  1. Wash the plums and place them in a preserving kettle with a little water.

  2. Cook the plums until soft.

  3. Rub the pulp through a colander or coarse sieve to separate the skins and pits.

  4. Dip large freestone plums in boiling water until skins crack, then dip them in cold water to slip off skins and remove pits.

Make the butter

  1. If the pulp is very juicy, boil it down to thicken before adding sugar.

  2. For each measure of pulp, add ½ to ¾ measure of sugar.

  3. Cook slowly, stirring frequently, until thickened to your liking.

  4. Add cinnamon, allspice, and cloves to taste after cooking.

Jar and seal

  1. Pack the hot plum butter into hot sterilized jars and cover with hot paraffin, or sterilize as directed for apple butter.

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

What each ingredient does

Plums
Provide the fruit pulp that forms the body and flavor of the butter.
Sugar
Adds sweetness and helps thicken the pulp as it cooks down.

The step that matters

Cook slowly, stirring frequently, until thickened. Sugar and pulp can scorch on the bottom of the kettle if heated too fast or left unstirred, giving a burnt taste. Slow cooking with frequent stirring lets moisture evaporate evenly and the butter thicken without sticking.

Swap the plum

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

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

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