Why it works: Rum and sugar are a kitchen classic. They rank in the top 14% of all ingredient pairs, and cooks put them together in 2,908 recipes. Both carry beta-damascenone, which smells apple, rose. The science ↓
White Currant Shrub
Ingredients
Directions
Prepare the juice
Strip the fruit and prepare it in a jar as for jelly.
Strain the juice.
Make the shrub
Combine 2 quarts of white currant juice, 1 gallon of rum, and 2 pounds of lump sugar in a container.
Stir well and cover tightly, letting it stand overnight.
In the morning, stir again and strain through a sieve or coarse cloth, then through a jelly bag.
If not clear, strain again through the jelly bag and bottle for use.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- White currant juice
- Provides the tart fruit flavour and most of the liquid base of the shrub.
- Rum
- Acts as the spirit base and preserves the mixture while it stands.
- Lump sugar
- Adds sweetness that balances the acidity of the currant juice.
The step that matters
Straining until clear. Fine particles from the juice stay suspended unless removed, so a cloudy result usually means the mixture needs straining again through the jelly bag before bottling.
Swap the white currant
How well each one fits the dish's main ingredients (rum, sugar):

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