Bring milk, water and celery root to a simmer in a large saucepan over medium heat. Reduce the heat to maintain a gentle simmer and cook until very tender, about 30 minutes. Reserve 1 cup of the cooking liquid, then drain. Puree the celery root, butter, salt and pepper in a food processor (or blender) until smooth and the consistency of thinned mashed potatoes.
Putting Down Roots. Congrats! You've now got your very own celery plant. Make sure you keep it sufficiently watered and fertilized. Once the new stalks begin really coming in, cut the top and bottom off of a two-liter soda bottle and place the cylinder around the celery plant. This will keep the stalks growing up, rather than out, which makes harvesting much easier. Speaking of harvesting, you can cut stalks from the plant as needed from now on.
