Why it works: Mushroom and pepper are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 13,580 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓
Baked Mushrooms on Toast
Ingredients
Directions
The book says “a gentle oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat your oven to 300°F (150°C).
Assemble and bake
Place the mushrooms on the toast and cover with clotted cream or melted butter.
Season with salt and pepper to taste.
Bake under a glass or basin for about 15 minutes.
Rest and finish
After baking, let it sit for a few minutes before removing the glass to allow the vapor to condense into the toast.

Cream and pepper barely smell alike, yet cooks put them together in 21,449 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
- Mushrooms
- Provide the main savory filling, releasing moisture as they heat and softening the toast beneath.
- Clotted cream or melted butter
- Adds fat and richness, carrying flavour and moistening the toast.
The step that matters
Covering and resting under the glass. The glass traps steam around the mushrooms, which cooks and softens them and moistens the toast. Lifting the glass too early lets that steam escape, leaving the topping drier and less evenly cooked, so let it rest briefly before removing it.
