Melt butter in a large skillet. Add onion and caraway seed. Cook 5 minutes or until onion is tender. Add water, vinegar, salt and hot sauce, and mix well. Then add the cabbage and mix well again. Cover and let simmer about 15 minutes, or until the cabbage is crisp-tender.
* A spicy warm slaw, this came originally from our local newspaper. We enjoy it a lot. Yield: serves 4-6.
