Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Their starch breaks down during simmering, thickening the broth and giving the stew body.
- Meat
- Slow simmering breaks down connective tissue, making the meat tender and enriching the broth.
- Onions
- As they soften and cook down, they add sweetness and savory depth to the broth.
- Carrot
- Cooks down to add gentle sweetness and color to the stew.
The step that matters
Bring to a boil, then reduce heat and simmer. A hard, rolling boil toughens meat proteins and breaks potatoes unevenly. A gentle simmer lets the meat become tender and the potatoes soften steadily into the broth.
