Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef
- Provides savory meat flavor and substance to the soup as it simmers.
- Peas
- Thicken the broth as they break down and add body and earthy sweetness.
- Potatoes
- Soften during simmering and help thicken the soup with their starch.
- Rice
- Absorbs liquid and adds body, thickening the soup as it cooks.
The step that matters
Boil gently until reduced to 4 pints. A gentle simmer lets the peas and potatoes soften and release starch slowly, thickening the soup evenly. A hard boil can break up the ingredients unevenly and scorch the bottom of the pot.
