Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Carrots
- Release sweetness and body into the stock as they soften during long stewing.
- Onions
- Add savory depth and sweetness as they break down during slow cooking.
- Butter
- Adds richness and carries aroma from the vegetables into the liquid.
- Peas
- Contribute starch and a mild sweetness that adds body to the stock.
The step that matters
Stew until the liquid is nearly evaporated. Reducing the liquid concentrates the flavors from the vegetables. Stopping too early leaves the stock weak, while reducing too far can scorch the vegetables on the pan bottom.
