Strawberry Jelly

Ingredients

Directions

Prepare the juice

  1. Press the strawberries through a jelly press or boil and mash them to a pulp.

  2. Strain the pulp through a flannel bag.

  3. Hang the bag on a strong nail to let it drip into a bowl.

  4. Prepare your jelly glasses by rolling them in hot water.

Make the jelly

  1. In a preserving kettle, combine 1 pint of juice and 1 pint of sugar.

  2. Set the kettle on red-hot coals and bring to a boil.

  3. Stir in the sugar with a silver spoon once boiling.

  4. Add fine kindling wood under the kettle and boil hard for 5 minutes.

  5. The jelly will thicken and boil with a 'thud' when ready.

  6. Pour into glasses, filling them to the brim, and reserve 1 pint of juice for the next batch.

  7. For firmer jelly, add lemon juice to the strawberries or boil a vanilla bean with the berries for flavor.

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

What each ingredient does

Strawberry juice
Provides the fruit flavour and the base that the sugar sets into jelly.
Sugar
Sweetens the jelly and, with the fruit's pectin and acid, helps it set firm.
Lemon juice
Adds acidity that supports pectin setting and brightens the strawberry flavour.

The step that matters

Boiling until the jelly is ready. Jelly sets only when enough sugar and pectin are concentrated by a hard boil. Stopping too early leaves it runny, while boiling too long can make it stiff and dull in flavour.

Swap the lemon

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

  1. Blueberryfits better
  2. Bananafits better
  3. Peachfits better
  4. Lemonthe original

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