Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Buttermilk
- Provides the tangy liquid base that the egg and flour thicken.
- Egg
- Coagulates when heated, helping to thicken and give the drink body.
- Flour
- Thickens the boiling mixture through starch gelatinization when mixed with cold buttermilk first.
- Toasted bread
- Adds toasty, browned flavor and body as it soaks in the hot liquid.
- Butter
- Adds richness and a silky mouthfeel to the finished drink.
The step that matters
Mixing the flour with cold buttermilk before adding it. Flour clumps when dropped into hot liquid. Blending it with cold buttermilk first keeps the starch dispersed, so it thickens smoothly when stirred into the boiling mixture.
