Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Ground pork
- Forms the savory filling that stays moist and firm as it cooks.
- Egg
- Binds the pork mixture so it holds together inside the peppers.
- Green peppers
- Act as the edible shell that softens while the filling cooks.
- Tomatoes
- Add moisture and acidity to the stewing liquid in the pan.
- Onion
- Softens in butter to add sweetness and aroma to the base.
The step that matters
Stewing the peppers until tender. Cooking covered over gentle heat lets the pepper walls soften and the pork cook through without the sauce drying out or scorching.
