Why it works: Mustard and celery are a kitchen classic. They rank in the top 2% of all ingredient pairs, and cooks put them together in 4,169 recipes. Both carry guaiacol, which smells smoky, sweet. The science ↓
Baked Bell Peppers
Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Cut the stem end of the peppers, remove the seeds and skin, and soak them in salted water for 30 minutes.
Make the filling
In a bowl, cream the butter and add the mustard, pepper, celery seed, nutmeg, and salt.
Beat in the egg, then mix in the bread crumbs and chopped shrimp.
Bake and serve
Stuff the mixture into the prepared pepper pods.
Bake in a 400°F (200°C) oven for 20 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Shrimp
- Provides the main filling, adding bulk and a savory seafood flavor.
- Egg
- Binds the filling so it holds its shape when baked.
- Bread crumbs
- Absorbs moisture and adds body to the filling, keeping it tender.
- Butter
- Adds richness and fat, carrying flavor through the creamed mixture.
- Green bell peppers
- Serve as edible shells that hold the filling and soften as they bake.
The step that matters
Stuffing the peppers. Pack the filling firmly into each pepper without tearing the skin, so it stays in place and cooks evenly. Peppers soaked beforehand are more pliable and less likely to split during stuffing.
