The following appetizing recipe is recommended by Robinson: "Cut
fresh Agarics in small pieces, cover the bottom of a pie-dish with
small, thin slices of bacon, and place the mushroom fragments upon
them, with the addition of salt and pepper; upon this place a layer of
mashed potatoes, following again with other similar layers of bacon,
mushrooms, and potatoes, until the dish is filled, the last layer of
potato answering for a crust; bake in the oven for half an hour, and
brown before a brisk fire."
Doubtless many other species of mushroom would lend themselves equally
well to this particular treatment.
