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 ↓
Mushrooms Under Glass
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
Trim off the stems and carefully pare the caps of the mushrooms.
Arrange a thin slice of toast on each glass or earthen dish.
Assemble and bake
Cover the toast with a few spoonfuls of heavy cream and dust with coarse sea salt and black pepper.
Place as many mushrooms as the toast will hold on top.
Cover with a glass dome and place in a hot oven at 400°F (200°C) for 15 to 20 minutes.

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
- Large thick mushrooms
- Form the main body of the dish, softening and releasing their juices as they bake.
- Toast
- Provides a absorbent base that soaks up the cream and juices beneath the mushrooms.
- Heavy cream
- Adds richness and moisture, gently coating the mushrooms and toast as it heats.
The step that matters
Placing the mushrooms on the toast. Mushrooms hold a lot of water, so overcrowding the toast can leave them steaming rather than gently cooking. Arrange them so the cream can surround them evenly.
