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

What each ingredient does

Flour
Thickens the liquid into a porridge as it cooks.
Raisins
Add sweetness and chewy texture as they soften in the liquid.
Cold milk
Mixed with the flour first so it disperses evenly without lumps.

The step that matters

Mixing the flour and cold milk before adding to the water. Flour dropped directly into hot liquid clumps, because its outer layer hydrates and gels before the inside wets. Blending it smooth in cold milk first lets it disperse evenly.

Swap the nutmeg

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

  1. Cinnamonfits better
  2. Nutmegthe original
  3. Jalapenofits about as well
  4. Turmericfits less well

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