For the woman who wondered what to do with a bulb of celeriac, here is a winter soup made of vegetables from this week’s CSA vegetables. Ingredients: celery root, leek, potatoes, apple, garlic, olive oil, salt, pepper, and water or vegetable stock. Directions: soften chopped leeks in hot oil, add the chopped root vegetables, garlic and apple. Heat. Add stock or water. Simmer until ingredients are very soft. Blend. I topped with frizzled leeks, but you could also sip it from a mug.
