Unboiled Black Currant Syrup

Ingredients

Directions

Layer the fruit

  1. Layer black currants and sugar in a jar, using equal weights of each.

  2. Add sugar to the top and bottom, shaking the jar hard between each layer.

  3. Optionally, add a clove or two or a few allspice berries.

Seal and steep

  1. Soak sheets of stout white paper in brandy and lay them on top before sealing.

  2. Seal the jar with bladder or use bottles and cork them securely.

  3. After three months, draw off the syrup and bottle it for future use, adding a little spirit if desired.

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

What each ingredient does

Black currants
Provide the fruit flavour and the juice that dissolves the sugar into syrup.
Sugar
Draws juice out of the fruit and sweetens the syrup while helping it keep.
Brandy
Adds alcohol that helps preserve the syrup and supports its keeping.

The step that matters

Shaking the jar between sugar layers. Shaking spreads the sugar through the fruit so it coats the currants evenly. Sugar that stays in clumps draws juice unevenly and can leave parts of the fruit poorly preserved.

Swap the clove

The recipe marks clove as optional. How well each one fits the dish's main ingredients (black currant, sugar, allspice, brandy):

  1. Cinnamonfits better
  2. Clovethe original
  3. Nutmegfits about as well
  4. Gingerfits less well

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