Mushrooms on Toast

Oven, in the book's wordsA hot oven

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.

Cut the bread into small rounds.
Toast the bread lightly.
Butter both sides of the toasted bread well.
Place a good-sized skinned mushroom on each round.
Bake in a hot oven at 400°F (200°C) for 5 to 10 minutes until fully cooked.
Serve very hot, garnished with lemon slices and parsley sprigs.

Recipe from a historical cookbook (Internet Archive).

Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.
