Flour and milk barely smell alike, yet cooks put them together in 78,219 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

Flour
Thickens the liquid as its starch swells with heat, giving the caudle body.
Milk
Provides the liquid base and richness that the flour thickens into a warm drink.

The step that matters

Cook carefully to prevent burning. Flour-thickened liquids scorch easily on direct heat, and milk proteins and sugars can stick and brown at the base of the pan. Gentle heat, such as a double saucepan, spreads the heat evenly and protects the texture and flavour.

Swap the cinnamon

The recipe marks cinnamon as optional. How well each one fits the dish's main ingredients (flour, milk):

  1. Jalapenofits better
  2. Cinnamonthe original
  3. Nutmegfits less well
  4. Turmericfits less well

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