This is one of the best of the mushroom dishes. Put small flap mushrooms on a plate that will stand the fire and lay a morsel of butter in each; add salt and pepper, a squeeze of lemon and a drop of water, and press a strip of paste around the rim of the plate; the mushrooms must be in a single layer only. Press a second plate over, pressing it well into the paste; this is to keep in the flavor. Then bake in a good oven 25 minutes. Take the top plate off, remove the paste and put in the place of it some croutons of any desired shape, sufficient to cover the rim of the plate.
