Saute one chopped onion or leek in two TBSp butter with a chopped garlic clove and 2 TBSP chopped celery or bok choi until just cooked and soft. Add 5 cups chicken or vegetable stock and two large potatoes cubed. Cook potatoes in stock until soft, then puree. Remove stems from a bunch of kale, chop and add to the soup 5 minutes before serving. Do not over-cook the kale or it will taste too strong. Salt and pepper to taste. Cooked sausage, ham or Scotch Hill Farm brats are a nice addition for a heartier winter soup. Also, hot peppers can be added if you like a spicy soup. Kale is one of nature’s best medicines. It’s very good for you!
