1 lb. carrots
1 lb. turnips or rutabagas
1 tsp. salt
2 tbsp. butter
1/2 tsp. white pepper

Peel and slice carrots, peel and dice turnips. Put together in a pot with almost enough water to cover. Bring to a boil, reduce heat and cook 15 to 20 minutes until tender. Drain water, reserving in case you need some while mashing, so it's not dry. Mash with potato masher, adding salt, pepper and butter.
