Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Spanish onion
Forms the edible shell that holds the forcemeat and softens as it cooks.
Forcemeat
Provides the rich, savory filling that cooks through inside the onion.
Bacon
Covers the onion and releases fat that adds savory flavor and browning.

The step that matters

Cook over medium heat until done. Medium heat lets the onion and forcemeat cook through gently. Higher heat can scorch the bacon and sugars in the onion before the center is tender, and the sauce may reduce too fast.

Swap the parsley

How well each one fits the dish's main ingredients (onion, chicken, ham, mushroom, pepper):
