Step 1: Heat butter in a heavy pot over low heat, stir in onions, cover and cook for about 10 minutes, stirring occasionally until golden.
Step 2: Add celery root, potatoes, salt, celery seed, water, and 2 cups of milk to the onions. Stir, and bring to a boil, reduce heat and simmer gently covered for 30 minutes or until the vegetables are very tender.
Step 3: Puree (but leave it a little lumpy and chunky) in batches with a blender or food processor, or use an immersion blender right in the pot.
Step 4: Stir in more milk to desired consistency. Stir in salt and white pepper to taste. Reheat if needed.
Step 5: Suggested to top with chopped herbs, croutons sauteed in butter, diced ham or sausage or anything else you have on hand that sounds good! Enjoy!
