Why it works: Potato and rice match in chemistry and in kitchens. They rank in the top 7% of all ingredient pairs, and cooks put them together in 851 recipes. Both carry 2-acetyl-1-pyrroline, which smells popcorn, roasted. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lean beef
- Provides the main savory meat flavor and substance of the soup.
- Whole or split peas
- Thicken the soup as they soften, giving it body and a hearty texture.
- Potatoes
- Break down slightly as they cook, adding starch that helps thicken the broth.
- Rice
- Absorbs liquid and softens during simmering, adding body to the soup.
The step that matters
Boil gently until reduced to 4 pints. A gentle simmer lets the beef, peas and potatoes become tender without toughening the meat or breaking the potatoes apart. A hard boil evaporates liquid unevenly and can make the soup cloudy and the meat stringy.
