Why it works: Buttermilk and flour are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 3,721 recipes. Both carry ethanol, which smells alcoholic, ethereal. The science ↓
Mulled Buttermilk
Ingredients
Directions
Heat the buttermilk
Place the buttermilk in a bowl and set it in a saucepan of cold water over the fire. Stir slowly while heating.
Thicken and finish
Mix the flour with a little buttermilk or water until smooth.
When the buttermilk is slightly warmer than lukewarm, stir in the thickening.
Continue stirring until it looks grainy as it runs from the spoon.
Remove from heat and keep stirring for 5 to 10 minutes.

The flavor team
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.

What each ingredient does
- Buttermilk
- Forms the liquid base and gives the drink its tangy, slightly sour flavour.
- Flour
- Its starch swells when heated, thickening the buttermilk to a light body.
The step that matters
Heat gently and keep stirring as it thickens. Buttermilk is acidic and its proteins can curdle or separate if it gets too hot too fast. Stirring keeps the flour starch evenly dispersed so lumps do not form.
