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

What each ingredient does

Peanut butter
Adds richness and a nutty flavor that carries through the filling.
Soft fine bread crumbs
Absorb moisture and give the filling body so it holds its shape.
Hot milk
Provides moisture during baking so the filling and shells do not dry out.

The step that matters

Cut out the center of each onion to leave a thin shell. Cooked onions are soft and easily torn. Removing the center carefully keeps the shell intact to hold the filling, while leaving it thin enough to cook through during baking.

Swap the onion

How well each one fits the dish's main ingredients (bread, peanut, butter, milk):
