8 parsnips, peeled and cut into 2 inch pieces
2 carrots, peeled and cut into 2-inch pieces
¼ cup snipped chives
6 tablespoons butter, divided

Place parsnips and carrots into a large pot and cover with salted water. Bring to a boil over high heat, then reduce heat to medium-low, cover, and simmer until tender, 15 to 20 minutes. Drain; return vegetables to pot. Turn heat to low, stir in chives and 3 tablespoons butter.
Begin to puree the mixture using an immersion blender. Add 3 tablespoons butter and continue to purée until the mixture is smooth. Season with salt and pepper to taste.
