Root Vegetable Gratin with Gruyere
Collective Bias sponsored a recipe swap, and luckily I was paired with my friend from What Megan's Making. When she sent me the recipe, she said that she had seen celery root at Meijer; I told her that I happened to have one in my refrigerator from my CSA (they last forever, it seems). "Only you would have celery root already in your refrigerator," she said. We had a good laugh, and I set off to get the rest of the ingredients.
