with salted water before
putting away. The precaution of scalding through several waters is a
wise one to use in the preparation of all mushrooms inasmuch as the
poisonous principle of most mushrooms is soluble in scalding water.
Dilute vinegar is frequently used in the same manner. Vinegar should not
be used in metal vessels unless porcelain-lined.
