Red-currant Jelly

Ingredients

Directions

Prepare the fruit

  1. Combine red and white currants in a large pot with water.

  2. Bruise the currants with your hands and remove any stalks.

  3. Heat the mixture until it begins to boil, then press the fruit to extract the juice.

Make the jelly

  1. Weigh the juice and add ¾ pound of sugar for each pound of juice.

  2. Stir until the sugar is dissolved, then bring to a boil.

  3. Skim off any foam, reduce heat to prevent boiling over.

  4. When the jelly drapes from a skimmer, remove from heat.

Set and seal

  1. Pour into jars and let set for two days.

  2. Cover jars with rounds of white paper dipped in brandy and seal with another layer of paper or bladder.

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

What each ingredient does

Red currants
Provide the main fruit flavour and natural pectin that helps the jelly set.
White currants
Add extra pectin and a milder, brighter flavour to the jelly.
Sugar
Sweetens the juice and, when boiled, helps the jelly thicken and set.

The step that matters

Judging when the jelly is done. Boiling too long or too briefly changes the set. The jelly is ready when it drapes in a sheet from a skimmer, showing enough sugar and pectin have concentrated to gel as it cools.

Swap the white currant

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

  1. Raspberryfits better
  2. Vanillafits better
