Why it works: Buttermilk and sugar match in chemistry and in kitchens. They rank in the top 9% of all ingredient pairs, and cooks put them together in 2,973 recipes. Both carry ethanol, which smells alcoholic, ethereal. The science ↓
Two-milk Whey
Ingredients
Directions
Make the whey
In a pot, boil together the new milk and buttermilk until a curd forms.
Remove from heat and let it sit by the fire to settle.
Strain off the whey.

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
- New milk
- Provides the main liquid and proteins that coagulate into curds when heated with the acid.
- Buttermilk
- Its acidity causes the milk proteins to curdle, separating the curd from the liquid whey.
The step that matters
Boiling until a curd forms. Heating the milk and buttermilk together lets their acid coagulate the milk proteins. Stopping too early leaves the mixture thin, while overheating can make the curds tough and grainy.
