Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds richness and flavor, and carries heat evenly to the vegetables.
- Mushrooms
- Add earthy, savory flavor and release moisture as they cook.
- Curry powder
- Adds warm, aromatic spice flavor to the stew.
The step that matters
Cooking the stew for 2 hours. With only 4 tablespoons of water, the stew can dry out and scorch during a long simmer. A gentle, covered-enough simmer with occasional stirring lets vegetable cell walls soften and flavors concentrate evenly.
