What each ingredient does

Buttermilk
Forms the liquid base and gives the drink its tangy flavour.
Egg
Thickens the boiling liquid as its proteins set, giving body to the drink.
Flour
Thickens the buttermilk by swelling with liquid and adds body.

The step that matters

Adding the egg to the boiling buttermilk. Egg proteins set when heated, so pouring beaten egg into boiling liquid can scramble it into lumps. Adding it steadily while stirring, or tempering it first, keeps the drink smooth.
