Crab-apple Jelly

Ingredients

Directions

Prepare the fruit

  1. Quarter the ripe crab-apples without peeling or coring them.

  2. Place the apples in a preserving kettle and heat slowly on the stove.

  3. If the apples are very dry, add a little water, just enough to not cover the fruit.

Extract the juice

  1. Boil slowly until the apples are tender and broken into pieces.

  2. Pour the mixture into a flannel bag, allowing the juice to drip through without squeezing the pulp.

  3. Measure the juice and proceed as you would with currant jelly, using 1 pound of sugar for each pint of juice.

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

What each ingredient does

Ripe crab-apples
Provide the pectin and acid that let the juice set into a jelly.
Sugar
Sweetens the juice and helps it gel when cooked to the right concentration.

The step that matters

Let the juice drip without squeezing the bag. Squeezing forces pulp and small solids through the flannel, which makes the jelly cloudy. Gentle dripping keeps the juice clear.

Swap the apple

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

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

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