Why it works: Butter and bread are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 27,232 recipes. Both carry delta-decalactone, which smells sweet, creamy. The science ↓
Mushrooms and Eggs
Ingredients
Directions
The book says “a sharp oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the mushrooms
Cut mushrooms in halves.
Stew them in water with 2 tablespoons butter, coarse sea salt, and black pepper for 10 minutes.
Drain the mushrooms.
Place them in a deep dish.
Assemble and bake
Break enough eggs over the mushrooms to cover the top.
Season with coarse sea salt and black pepper.
Spread bits of butter and grated bread crumbs on top.
Thicken the remaining liquid with 1 tablespoon brown flour.
Pour it over the dish.
Bake in a sharp oven at 400°F (200°C) until the eggs are set.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set when heated, forming the custard-like topping that holds the casserole together.
- Mushrooms
- Provide the main bulk and earthy flavour, releasing moisture as they stew.
- Brown flour
- Thickens the cooking liquid so it becomes a light sauce rather than runny.
- Butter
- Adds richness and fat, carrying flavour and helping the top brown lightly.
The step that matters
Baking until the eggs are set. Eggs turn firm at about 160°F (70°C) and keep cooking as they cool. Removing the dish too early leaves a runny topping, while overbaking makes it rubbery and dry.
