Why it works: Milk and beer work together. They rank in the top 13% of all ingredient pairs, and cooks put them together in 298 recipes. Both carry methyl 2-methylbutyrate, which smells fruity, apple. The science ↓

Ingredients
Directions
Prepare
Dissolve the yeast in a small amount of warm milk.
Add the dissolved yeast to the quart of milk.
Add sugar or syrup to taste.
Ferment and serve
Seal the mixture in clean bottles and leave at a temperature of 52°F to 62°F for 2.5 days.
Turn the bottles 2-3 times to mix the curd with the liquid, but do not shake.
Serve when it appears like thick whipped cream.

Milk and sugar barely smell alike, yet cooks put them together in 77,875 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
- Milk
- Forms the base liquid and the curd that ferments into the drink.
- Yeast
- Ferments the milk sugars, producing carbon dioxide and alcohol that give the drink its fizz and sourness.
- Sugar or syrup
- Provides sweetness and food for the yeast, adding to fermentation.
The step that matters
Turn the bottles without shaking. Gentle turning mixes the curd with the liquid while keeping the fragile curd intact. Shaking can break it up and release gas unevenly, so the texture can turn out thin rather than thick and creamy.
