Mrs. Hussey recommends stewing in brown or white sauce; in the latter case it will closely suggest "oyster sauce."
Another mushroom—the Lactarius deliciosus—stewed in a similar manner closely suggests the flavor of lambs' kidneys.
12 Roast Mushrooms
Mr. Palmer recommends the following: "Cut the larger specimens into fine pieces and place them in a small dish, with salt, butter, and pepper to taste; put in about two tablespoonfuls of water, then fill the dish with the half-open specimens and the buttons; cover tightly and place in the oven, which must not be overheated, for about ten minutes. The juice of the larger mushrooms will keep them moist, and, if fresh, yield a most abundant gravy."
13 Baked Russula
See that the mushrooms are free from dirt and grit on tops and stems, or rinse in cold water, afterwards wiping them dry and shaking off the water from the gills; make a mince of the stems, bread-crumbs, sweet herbs, pepper, salt, and a little butter or oil; pile this upon the gills; place the mushrooms in a shallow dish in a hot oven and baste them frequently with the melted butter or oil. In about fifteen minutes they will be ready to serve.
The Oyster Mushroom or its congener, the Agaricus ulmarius, might both be treated by this method, the oyster or fish-like flavor of these species thus affording a distinct second course for our menu. Either of these Pleurotus species may also be treated so as to closely suggest an escalop of oyster or fish.
14 Baked Procerus
Remove the stems; do not rinse the mushrooms unless they are soiled, and this species is usually conspicuously clean; put some slices of toast in a well-buttered pie-dish, and, with a little melted butter or cream poured over them, lay in the mushrooms; sprinkle with pepper, salt, and a small quantity of minced parsley which has previously been rubbed with onion or garlic; cover the dish with a plate and bake in a hot oven for fifteen minutes and serve in the dish. The aroma is thus conserved, and, upon being released at the table, will prove a most savory appetizer.
