Ingredients

Directions

The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.

Assemble

  1. Place a slice of tomato on each round of toast.

  2. Add a small mushroom on top, with the stalk and peel removed.

  3. Put a small piece of butter in the center of each mushroom.

Bake and serve

  1. Bake in a moderate oven at 350°F (175°C) until the mushrooms are tender.

  2. Serve hot, sprinkled with finely-chopped parsley.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Mushrooms
Soften during baking and provide the main savory filling on each toast.
Butter
Adds moisture and richness as it melts over the mushrooms during baking.
Tomato
Adds moisture and a bright acidic flavor beneath the mushroom.

The step that matters

Baking until the mushrooms are tender. Mushrooms release water and shrink as they cook. Baking until they are fully tender concentrates their flavor and keeps the toast from becoming soggy, while underbaking leaves them tough.

Swap the tomato
