Another great idea that came to us is a method for making very low-fat French fries. We have used this with potatoes, celeriac and parsnips with great results. Simply chop your roots into fries. In a large Tupperware container with a lid mix 2 Tbs olive oil with a teaspoon or so of mustard (vary the amount to you r taste). Add the fries, close the lid and shake so that the fries are evenly coated with the mixture. Bake in a 350 degree oven for 30-45 minutes turning the fries over occasionally until the fries are evenly golden brown.
