122. PUREE OF MUSHROOMS.
CLEAN a pottle of white button mushrooms, chop them up, adding meanwhile a juice of half a lemon to prevent them from turning black; when chopped fine, place them in a deep sauta-pan with a pat of butter, and with a wooden spoon stir them on the fire for five minutes; moisten with a ladleful of good white sauce, reduce the purée quickly, and then add half a pint of double cream; stir the purée on the fire for five minutes longer, rub it through a tammy on to a dish, and from thence remove it into a small stewpan for use.
