Why it works: Lemon and borage match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 102 recipes. Both carry acetic acid, which smells sour, vinegar. The science ↓
An Admirable Cool Cup
Ingredients
Directions
Make the base
Weigh the sugar and extract the essence from the lemon rind by rubbing it on the sugar.
Put the sugar into a deep jug and add the strained lemon juice.
Once the sugar is dissolved, pour in the cider and sherry.
Finish and serve
Add the grated nutmeg and serve with or without fresh balm or borage.
For a refreshing summer beverage, cover and chill on ice for a short time.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sugar
- Sweetens the drink and, rubbed on the rind, draws out the lemon oils for aroma.
- Lemon juice
- Adds acidity that balances the sweetness and brightens the drink.
- Cider
- Forms the main liquid base and adds its own fruity flavour.
- Sherry
- Adds body and a dry, wine-like depth to the drink.
- Nutmeg
- Contributes a warm, aromatic spice note.
The step that matters
Dissolving the sugar before adding the cider. Sugar dissolves much more readily in the lemon juice when it is already in a deep jug and mixed, so waiting until it is fully dissolved keeps the drink smooth and evenly sweetened rather than gritty at the bottom.
Swap the borage
The recipe marks borage as optional. How well each one fits the dish's main ingredients (sugar, lemon, cider, sherry, nutmeg):
- Cinnamonfits better
- Allspicefits about as well
- Thymefits about as well
- Boragethe original
Fit is the average pairing score against sugar, lemon, cider, sherry, nutmeg. Candidates are from the same food group and used in at least 100 recipes.
