Ingredients
Directions
Prepare the onions
Peel the onions and boil until tender.

Baste with hot milk before cooking.
Bake in the oven for 15 minutes.
Baste with hot milk twice during cooking.
Serve
Serve with cream sauce, using the milk from the dish as part of the liquid.

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):
- Potatofits better

- Asparagusfits better
- Onionthe original
Fit is the average pairing score against bread, peanut, butter, milk. Candidates are from the same food group and used in at least 100 recipes.
