Remove the stems, and place the mushrooms in a double wire broiler over
the coals, with the gill sides down, for about two minutes, or even
less if the specimens are small. The broiler should then be turned, and
the cooking should proceed for two minutes more; towards the end of
that time the juicy gills should be sprinkled with salt and pepper, a
small piece of butter being finally melted in each as they are served
on the hot toast. By this simple method all the natural juices of the
mushroom are retained and the true aroma and flavor is conserved. Bacon
toasted over the mushrooms is considered by some to improve the flavor.
