Birch Wine

Ingredients

Directions

Collect the juice

  1. Bore a hole in a birch tree, one foot from the ground, and insert a faucet to collect the juice for 2-3 days.

  2. Stop the hole with a peg for future use.

Make the wine

  1. Combine the juice with honey or sugar, and stir well.

  2. Boil the mixture for 1 hour, skimming continuously, and add cloves and lemon peel.

  3. When nearly cool, add enough yeast to make it work like ale.

  4. Once it begins to settle, pour the liquor into a cask.

  5. For every 20 gallons, add 1½ cups of finings and the whites and shells of 4 eggs, stir briskly, and let it stand for 6 weeks or longer.

  6. Bottle it off, and it will be ready to use in 2 months, improving with time.

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.

Lemon and egg barely smell alike, yet cooks put them together in 44,316 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 tree juice
Provides the base liquid and the sugars that yeast ferments into alcohol.
Honey or sugar
Supplies the fermentable sugar that yeast converts, setting the strength and sweetness of the wine.
Yeast
Ferments the sugars into alcohol and carbon dioxide, driving the fermentation.
Eggs
Their whites and shells help fining, clearing suspended particles so the wine becomes clear.

The step that matters

Adding the yeast when nearly cool. Yeast is killed by high heat, so adding it to liquid that is still hot can stop fermentation. Waiting until the mixture is nearly cool lets the yeast start working reliably.

Swap the clove

How well each one fits the dish's main ingredients (honey, lemon, egg):

  1. Dillfits better
  2. Thymefits better
  3. Parsleyfits better
  4. Clovethe original

Fit is the average pairing score against honey, lemon, egg. Candidates are from the same food group and used in at least 100 recipes.
