Why it works: Mushroom and parmesan cheese are a kitchen classic. They rank in the top 6% of all ingredient pairs, and cooks put them together in 1,199 recipes. Both carry methyl 2-methylbutyrate, which smells apple, fatty. The science ↓

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 the toast
Trim the bread slices evenly.
Toast the bread slices until light brown.
Assemble the canapés
Spread a little mustard on each slice of ham.
Place the mustard-coated ham slices on the toasted bread.
Add a layer of cooked mushrooms and tomatoes on top of the ham.
Dredge grated Parmesan cheese over the top.
Sprinkle fresh bread crumbs over the cheese.
Bake and serve
Bake in a 400°F (200°C) oven for 10 minutes.
Transfer the canapés to a heated dish.
Cover the dish with a folded napkin.
Serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Bread slices
- Provide a toasted base that holds the topping without going soggy.
- Lean cooked ham
- Adds savory, meaty flavor and a substantial layer on the bread.
- Grated parmesan cheese
- Melts and browns during baking, adding savory flavor and a golden crust.
- Fresh bread crumbs
- Add a crisp, browned texture on top of the cheese.
- Cooked mushrooms
- Contribute earthy flavor and moisture to the topping.
The step that matters
Bake in a 400°F (200°C) oven for 10 minutes. Baking is short, so the cheese and crumbs must brown without drying out the ham and vegetables. Watching the color, not just the clock, prevents underbaking or scorching the topping.
Swap the mustard
How well each one fits the dish's main ingredients (bread, ham, mushroom, tomato, parmesan cheese):
- Asparagusfits better
- Capsicumfits better
- Spinachfits better
- Mustardthe original
Fit is the average pairing score against bread, ham, mushroom, tomato, parmesan cheese. Candidates are from the same food group and used in at least 100 recipes.
