Why it works: Brandy and raisin are a kitchen classic. They rank in the top 13% of all ingredient pairs, and cooks put them together in 2,768 recipes. Both carry beta-damascenone, which smells apple, rose. The science ↓
Birch Wine
Ingredients

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.

Sugar and brandy barely smell alike, yet cooks put them together in 11,939 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
- Birch sap
- Forms the bulk liquid of the wine and carries its flavour.
- Fine white sugar
- Provides sweetness and the sugar that yeast converts into alcohol.
- Yeast
- Ferments the sugars into alcohol and carbon dioxide.
- French brandy
- Raises the alcohol content and strength of the finished wine.
- Stoned raisins
- Adds fruity flavour and some natural sweetness.
The step that matters
Burn a brimstone match in the barrel before sealing. Burning sulfur releases sulfur dioxide, which inhibits unwanted microbes and oxidation. Sealing the barrel without this step leaves the wine more open to spoilage during fermentation and storage.
Swap the raisin
How well each one fits the dish's main ingredients (sugar, brandy):
- Vanillafits better
- Apricotfits about as well
- Raisinthe original
- Figfits about as well
Fit is the average pairing score against sugar, brandy. Candidates are from the same food group and used in at least 100 recipes.
