Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rice flour
- Thickens the broth into a smooth, light body as its starch swells when boiled.
- Broth or gravy soup
- Forms the liquid base that carries the flavor of the whole soup.
- Cream powder
- Adds richness and a mellow, creamy flavor to the soup.
- Lemon juice
- Adds acidity that brightens the flavor and balances the richness.
The step that matters
Mix the rice flour smooth before adding it to the broth. Rice flour clumps when it meets hot liquid directly. Stirring it into a little cold broth first separates the grains so they hydrate evenly and the soup thickens without lumps.
Swap the lemon
How well each one fits the dish's main ingredients (rice, flour, onion, pepper, cream, ham):

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