Plain mashed potatoes may seem a bit tame after you've tried this flavorful version, full of celery root, rutabaga and Yukon Gold potatoes and mashed with sweet garlic and tangy buttermilk. Finish the dish with a handful of snipped fresh chives.
Make Ahead Tip: Prepare through Step 2 and refrigerate for up to 2 days. Reheat in a double boiler and stir in the remaining butter and chives (Step 3) just before serving.
Tips: To peel celery root and rutabaga, cut off one end to create a flat surface to keep it steady. Cut off the skin with your knife, following the contour of the root. Or use a vegetable peeler and peel around the root at least three times to ensure all the fibrous skin has been removed.
No buttermilk? You can use buttermilk powder prepared according to package directions. Or make “sour milk”: mix 1 tablespoon lemon juice or vinegar to 1 cup milk.
