Place in a saucepan two ounces of butter, add two tablespoonfuls of flour, and stir constantly for five minutes. Moisten with a pint and a half of boiling milk, being careful to pour it in gradually; then beat it well with a whisk. Add half a teaspoonful of grated nutmeg, a pinch of salt, a bouquet (No. 254), twelve whole peppers, and a little mushroom liquor, if at hand. Cook well for fifteen minutes, and when done rub through a fine sieve.
