Name: Ginger Liqueur
Ingredients: 1 gallon strong malt whiskey; 4 pounds lump sugar; 1 pint boiling water; 5 ounces bitter almonds; 5 ounces sweet almonds; 5 ounces bruised ginger; rind of 6 lemons

Why it works: Ginger and lemon match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and 5,154 recipes mention both. Both carry beta-phellandrene, which smells minty, terpene. The science ↓

Sugar and ginger share little aroma chemistry, yet 14,053 recipes mention both: they likely 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

Malt whiskey: Serves as the alcoholic base that extracts and preserves the flavors of the other ingredients.
Lump sugar: Adds sweetness and body, balancing the alcohol and the bitterness of the almonds and ginger.
Bitter almonds: Contribute a characteristic nutty, almond aroma and flavor to the liqueur.
Bruised ginger: Provides the spicy, warm ginger flavor as its oils infuse into the spirit.
Lemon rind: Adds bright citrus aroma from the oils in the peel.

Fit is the average pairing score against malt, sugar, ginger, lemon. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
