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 acidity, and the juice that gives the cordial its colour.
Whiskey
Extracts flavour from the currants and acts as a preservative in the finished cordial.
Loaf sugar
Adds sweetness and balances the tartness of the currants.
Ginger
Adds a warm, spicy aroma that complements the fruit.

The step that matters

Strain the mixture through a flannel bag. Straining out the fine pulp and seeds clears the liquid. Filtering again after sweetening removes sediment that would otherwise cloud the cordial as it matures.

Swap the red raspberry

The recipe marks red raspberry as optional. How well each one fits the dish's main ingredients (red currant, sugar, ginger):

  1. Orangefits better
  2. Raspberryfits better
