Chipotle Mashed Potatoes

Combine the mashed potatoes, 4 tablespoons (60 ml) of the butter, and cream in a mixing bowl and stir to combine. Melt the remaining butter in a skillet and sauté the onion, pepper, and cumin until the onion is tender but not brown, about 5 minutes. Stir the onion mixture into the potatoes. Add the chipotle pepper (**note, that is one pepper, not one can of peppers), salt, and pepper, and taste to adjust the seasoning. Spoon the mixture into a buttered casserole and bake in a preheated 375F (190C) oven for 20 minutes.
