Remove the roots, carefully pick over (discarding all tough and wilted leaves) and wash dandelion leaves in several waters; to the last water add salt to free leaves from insects and vermin. It will require one peck of leaves to serve a family of six. Cook leaves in plenty of boiling salted water until tender; drain at once and chop fine. Dress with butter and pepper; cut thin slices of bacon in shreds crosswise, try it out and pour over dandelions. (There should be one-third cup bacon fat.) The shreds of bacon are an attractive garnish; hard-cooked eggs may also be used as a garnish. Cut them in eighths or rings. Vinegar is sometimes added. Serve hot.
