Crab-Apple Jelly

Ingredients

Directions

Prepare the juice

  1. Wash and quarter the crabs without coring them.

  2. Cover the crabs with cold water and cook until mushy.

  3. Pour the mixture into a coarse cotton bag or strainer and press to extract juice.

  4. Strain the juice through fine muslin or crinoline over a bowl, allowing it to drip slowly.

Make and jar the jelly

  1. For every pint of juice, add 1 pound of sugar and boil for 45 minutes.

  2. Pour into sterilized jars and seal.

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

What each ingredient does

Crab apples
Their natural pectin and acid help the juice set into a firm jelly.
Sugar
Sweetens the jelly and, with boiling, helps it thicken and set.
Lemon juice
Adds acidity that supports pectin setting and brightens the flavour.

The step that matters

Straining the juice slowly. Pressing the pulp or rushing the drip pushes solids into the juice, leaving the jelly cloudy. Slow dripping through fine muslin gives a clear jelly.

Swap the lemon

  3. Vanillafits about as well
