Get large bell peppers. Cut around the stem, remove it, and take out all the seeds. For the stuffing use two quarts of chopped cabbage, a cupful of white mustard seed, three table-spoonfuls of celery seed, two table-spoonfuls of salt, half a cupful of grated horse-radish. Fill each pepper with part of this mixture, and into each one put a small onion and a little cucumber. Tie the stem on again, put the peppers in a jar, and cover with cold vinegar.
