Kidney Bean Stew

Ingredients

Directions

Prepare the beans

  1. Wash the beans and soak them overnight in 2 quarts of cold water.

  2. Cook the beans in the soaking water over low heat for about 2 hours, adding more water if necessary to keep them covered.

  3. For added flavor, include the salt pork at the beginning of cooking.

Finish the stew

  1. Add the chopped onion and canned tomatoes to the beans and cook for another 30 minutes.

  2. Wash the rice and add it to the pot, cooking until tender.

  3. Mix the flour with a little cold water and stir it in to thicken the stew.

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

What each ingredient does

Kidney beans
Form the bulk of the stew and give it a creamy, starchy body as they cook.
Flour
Thickens the cooking liquid into a smooth, sauce-like stew when stirred in.
Canned tomatoes
Add acidity and moisture, building the stew's savory base.
Rice
Absorbs liquid as it cooks, adding body and making the stew more filling.

The step that matters

Stirring in the flour mixture. Flour must be mixed smoothly with cold water first; added dry or lumpy, it clumps and won't thicken evenly. Starch thickens the liquid only once it is heated, so the stew needs to be simmering while it is stirred.

Swap the kidney beans

How well each one fits the dish's main ingredients (flour, onion, tomato, rice, pork):

  1. Beansfits better
  2. Black-eyed peafits better
  3. Sesamefits better
  4. Kidney beansthe original

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