Take new firkins or large stone jars, and scald them well with boiling water before using. Vegetables that are boiled before pickling in a brass kettle always keep their fresh, green color. In salt pickling cover your jars or kegs with a clean, white cloth, then a cover made of wood and last a heavy stone to weigh it down. The cloth must be removed every other day, washed and put back. In doing this, take hold of the cloth at each corner, so that none of the slimy substance can get into your pickle, and wash the top and sides of the jar also.
