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 ↓

Brandy and sugar 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
- Buttermilk
- Forms the thick, tangy base of the drink, which is drained to concentrate it.
- Brandy or wine
- Adds alcohol and aroma that give the drink its character.
- Loaf sugar
- Sweetens the tangy buttermilk to balance its acidity.
- Raspberry jam
- Colors the drink and adds fruity flavor and sweetness.
The step that matters
Draining the buttermilk. Hanging the buttermilk for 2-3 days lets whey drain away, leaving a thicker, richer base. Stopping early leaves it watery, so the flavored drink ends up thin.
