MUSHROOMS AU GRATIN .-- This is a very delicious dish, and is often served as an entree at first-class dinners.

They are made from what are known as cup mushrooms.

It is best to pick mushrooms, as far as possible, the same size, the cup being about two inches in diameter.

Peel the mushrooms very carefully, without breaking them, cut out the stalks close down with a spoon, scoop out the inside of the cup, so as to make it hollow.

Now peel the stalks and chop them up with all the scooped part of the mushroom, with, supposing we are making ten cups, a piece of onion as big as the top of the thumb down to the first joint.
