  3. Strain the mixture without pressing the fruit.

  4. Add sugar to every pint of clear juice and stir until dissolved.

  5. Bottle and cork the syrup tightly and store in a cool, dark place.

Set and serve

The flavor team

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

    Shared aroma: ethanol (alcoholic, ethereal).

Currant and sugar barely smell alike, yet cooks put them together in 12,256 recipes: they work on texture and structure more than aroma.

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

What each ingredient does

Strawberries, currants, or raspberries
Provides the main flavour and the juice that becomes the syrup.
Tartaric acid
Adds sharp acidity that brightens the flavour of the fruit.
White sugar
Sweetens the clear juice and helps preserve the syrup.
Gelatine
Sets the syrup into a firm jelly as it cools.

The step that matters

Fully dissolve the gelatine before adding the syrup. Gelatine only sets when it is completely dissolved and then cooled. Undissolved granules leave a grainy, weak jelly, so stir until clear before adding the syrup and refrigerating.

Swap the currant

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

  1. Vanillafits better
  2. Raisinfits better
  3. Pearfits better
  4. Currantthe original

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