Why it works: Mushroom and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 12,525 recipes. Both carry trans-2-decenal, which smells waxy, orange. 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.
Assemble
Preheat the oven to 300°F (150°C).
Place the mushrooms on the toast.
Top with scalded or clotted cream and melted butter.
Season with coarse sea salt and black pepper.
Bake and serve
Cover with a glass or basin and bake for 15 minutes.
Let sit for a few minutes before serving to allow condensation to soak into the toast.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mushrooms
- Release moisture as they bake, which condenses under the cover and softens the toast.
- Scalded or clotted cream
- Adds richness and moisture, and its fat carries flavour across the toast.
- Melted butter
- Adds fat for richness and helps the toast brown lightly.
- Toast
- Provides a sturdy base that absorbs the mushroom juices and cream.
The step that matters
Cover while baking. The cover traps the moisture the mushrooms release, so they steam rather than dry out. Letting the dish rest then gives that condensation time to soak into the toast.
