Why it works: Ginger and lemon match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and cooks put them together in 5,154 recipes. Both carry beta-phellandrene, which smells minty, terpene. The science ↓
Old Fashioned Ginger Beer
Ingredients
Directions
Prepare
Crush the ginger and place it in a large tub with cream of tartar and sliced lemons.
Boil 2 gallons of water and pour it over the mixture, then cover and let it stand for 3 hours.
Make the ginger beer
Add the sugar and the remaining 8 gallons of water (5 gallons boiling and 3 gallons cold), and stir.
When the mixture cools to 80°F to 85°F, add the brewer's barm.
Beat the egg whites until frothy and stir them into the mixture with the barm.
Allow the ginger beer to ferment.

Sugar and ginger barely smell alike, yet cooks put them together in 14,054 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
- Ginger
- Provides the spicy flavor that defines the drink.
- Cream of tartar
- Adds acidity that sharpens the flavor and helps keep the mixture stable.
- Brewers’ barm
- Contains yeast that ferments the sugar and produces carbonation.
- Lump sugar
- Feeds the yeast during fermentation and supplies sweetness.
- Egg whites
- Help clarify the liquid by collecting particles as they are stirred in.
The step that matters
Adding the barm at the right temperature. Yeast is sensitive to heat. Adding the barm while the mixture is still hot can kill it, so the mixture should cool to the stated 80°F to 85°F range before the barm goes in.
Swap the ginger
How well each one fits the dish's main ingredients (sugar, cream, egg, lemon):
- Nutmegfits better
- Cinnamonfits better
- Tarragonfits better
- Gingerthe original
Fit is the average pairing score against sugar, cream, egg, lemon. Candidates are from the same food group and used in at least 100 recipes.
