Poland, many species
grow wild, and are used as food; but in Britain, two only are
generally eaten. These are mostly employed for the flavouring of
dishes, and are also dried and pickled. CATSUP, or KETCHUP, is
made from them by mixing spices and salt with their juice. The
young, called buttons, are the best for pickling when in the
globular form.

BROWN MUSHROOM SAUCE, to serve with Roast Meat, &c.

474. INGREDIENTS.--1/2 pint of button mushrooms, 1/2 pint of good beef
gravy, No. 435, 1 tablespoonful of mushroom ketchup (if at hand),
thickening of butter and flour.

_Mode_.--Put the gravy into a saucepan, thicken it, and stir over the
fire until it boils. Prepare the mushrooms by cutting off the stalks and
wiping them free from grit and dirt; the large flap mushrooms cut into
small pieces will answer for a brown sauce, when the buttons are not
obtainable; put them into the gravy, and let them simmer very gently for
about 10 minutes; then add the ketchup, and serve.

_Time_.--Rather more than 10 minutes.

_Seasonable_ from August to October.

_Note_.--When fresh mushrooms are not obtainable, the powder No. 477 may
be used as a substitute for brown sauce.

WHITE MUSHROOM SAUCE, to serve with Boiled Fowls, Cutlets, &c.

I.

475. INGREDIENTS.--Rather more than 1/2 pint of button mushrooms,
lemon-juice and water, 1 oz. of butter, 1/2 pint of Bechamel, No. 367,
1/4 teaspoonful of pounded sugar.

_Mode_.--Turn the mushrooms white by putting them into lemon-juice and
water, having previously cut off the stalks and wiped them perfectly
free from grit. Chop them, and put them in a stewpan with the butter.
When the mushrooms are softened, add the Bechamel, and simmer for about
5 minutes; should they, however, not be done enough, allow rather more
time. They should not boil longer than necessary, as they would then
lose their colour and flavour. Rub the whole through a tammy, and serve
very hot. After this, it should be warmed in a bain marie.

_Time_.--Altogether, 1/4 hour. _Average cost_, 1s.

_Seasonable_ from August to October.

II.

_A More Simple Method_.

476. INGREDIENTS.--1/2 pint of melted butter, made with milk, No. 380;
1/2 pint of button mushrooms, 1 dessertspoonful of mushroom ketchup, if
at hand; cayenne and salt to taste.

_Mode_.--Make the melted butter by recipe No. 380, and add to it the
mushrooms, which must be nicely cleaned, and free from grit, and the
stalks
