Why it works: Sugar and lemon are a kitchen classic. They rank in the top 18% of all ingredient pairs, and cooks put them together in 53,532 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓
White Spruce Beer
Ingredients
Directions
Prepare the wort
Boil the water and lump sugar together for 30 minutes, skimming regularly.
Pare the lemons as thin as possible and pour the boiling water over the rind.
Cover and let it cool, then squeeze in the juice of the lemons.
Ferment
Mix in the essence of spruce and yeast thoroughly.
Transfer to a cask and let it ferment for 4 days, topping up as needed.
After 4 days, draw off a little liquid and dissolve the isinglass in it.
Stir the dissolved isinglass back into the barrel and seal it.
Clarify and bottle
Let it stand for a few days to clarify, then bottle.

Shared aroma: 2-nonenal (fatty, green).
Sugar and lemon barely smell alike, yet cooks put them together in 53,532 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
- Lump sugar
- Provides the sugar that yeast ferments into alcohol and carbon dioxide.
- Yeast
- Ferments the sugar, driving the fermentation that makes the beer fizzy and alcoholic.
- Isinglass
- Fining agent that binds haze particles so they settle, clearing the beer.
- Lemons
- Add acidity and aroma from the juice and rind.
The step that matters
Dissolving the isinglass before stirring it in. Isinglass must be fully dissolved in liquid before it goes into the barrel so it disperses evenly and can bind haze particles for settling. Lumps would clarify the beer unevenly.
