The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Mace and pepper barely smell alike, yet cooks put them together in 12,257 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

Fine rice flour
Thickens the broth as its starch swells during boiling, giving the soup body.
Broth or gravy-soup
Forms the liquid base that carries the flavor and dissolves the thickening starch.
Curry powder
Adds aromatic spice flavor to the soup when stirred in at the end.
Lemon juice
Adds acidity that brightens the flavor of the soup.

The step that matters

Mix the rice flour with cold broth first. Rice flour clumps when added dry or to hot liquid, because its outer starch gelatinizes quickly. Blending it smooth in cold liquid first lets it disperse evenly before the soup boils and thickens.

Swap the lemon

The recipe marks lemon as optional. How well each one fits the dish's main ingredients (rice, flour, mace, pepper):

  1. Limefits about as well
  2. Lemonthe original
  3. Mangofits less well
  4. Raisinfits less well

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