Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Wheaten flour
Its starch and proteins thicken the liquid and give the gruel body.
Millet
Adds grain starch that thickens the mixture and gives it a grainy texture.
Honey
Adds sweetness and sugars that the yeast can ferment.
Beer yeast
Ferments the sugars, producing gas, alcohol and tangy flavour as the mixture stands.
Mare's milk
Forms the liquid base and supplies sugars that feed fermentation.

The step that matters

Let the mixture stand. The yeast needs time to ferment the sugars. Standing too briefly leaves the drink flat and underdeveloped, while standing too long can make it overly sour.

Swap the millet

How well each one fits the dish's main ingredients (flour, honey, beer, milk):

  1. Almondfits better
  2. Milletthe original
  3. Walnutfits about as well
  4. Beansfits about as well

Fit is the average pairing score against flour, honey, beer, milk. Candidates are from the same food group and used in at least 100 recipes.
