Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Green peppers
- Hollowed shells that hold the filling and soften as they bake.
- Cold meat
- Provides the savory, meaty body of the filling.
- Bread crumbs
- Absorb moisture and bind the filling so it holds together.
- Irish potatoes
- Add starch and body to the filling, making it hearty.
- Onions
- Add aromatic sweetness and depth of flavor as they cook.
The step that matters
Bake until the peppers are tender. Peppers need enough time in the oven for their walls to soften fully. Underbaked peppers stay firm and taste raw, while the hot water in the pan creates steam that helps them cook evenly.
