Why it works: Beer and sugar work together. They rank in the top 22% of all ingredient pairs, and cooks put them together in 699 recipes. Both carry beta-damascenone, which smells apple, rose. The science ↓
Old-fashioned Root Beer I
Ingredients
Directions
Prepare the yeast
Mix 1/4 ounce of yeast with 1 cup tepid water and let stand 10 minutes.
Make the root beer
Add the root-beer concentrate to the sugar, mix well and dissolve in 10 quarts of tepid water.
Add the yeast mixture, stir well and bottle the root-beer immediately, fastening the caps securely.
Ferment and serve
Set in a warm, draft‑free place for 3–4 days until the root beer becomes effervescent.
Serve chilled.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Shared aroma: beta-damascenone (apple, rose).
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Yeast
- Ferments the sugar, producing carbon dioxide that makes the root beer fizzy.
- Sugar
- Provides the fuel for yeast fermentation and adds sweetness to the drink.
- Root-beer concentrate
- Supplies the characteristic root beer flavor and aroma.
The step that matters
Fastening the caps securely. Yeast keeps producing carbon dioxide during fermentation. Loose caps can let the gas escape, leaving the root beer flat, or cause bottles to burst under pressure.
