I have always enjoyed sweet potatoes in a savory manner. I was putting together ways of making a mashed version and thought the kick of chipotle would be great. It was but I thought the addition of maple would be the counterpoint add that familiar sweet note. - ashleyza —ashleyza
Test Kitchen Notes
Here is a spunky, slightly deviant twist on the archetypal marshmallow-topped sweet potato casserole that won't throw off the whole feast or upset Grandma. In fact, we think it would suit everything from turkey to roast pork. Chipotle laces the fluffy mash with subtle heat and smokiness, and maple adds welcome depth without making it sticky-sweet. Ashleyza cleverly calls upon the microwave here to cook the potatoes swiftly. Of course you could boil or bake them if you prefer, but it's always nice -- especially during the holidays with full ovens and stovetops -- to have an escape hatch to get things done. - A&M —The Editors
Wash sweet potatoes and fork prick all sides. Microwave until cooked through. Once cooled enough, remove the skins. Then put the cooked sweet potatoes in a large bowl.
In a food processor or using an immersion blender (my choice) pulse the milk and chipotle together. In a saucepan bring the milk and chipotle mixture to a simmer on low. Then add the maple syrup, sour cream, butter, and salt and pepper to the milk mixture.
Pour the milk mixture over the cooked sweet potatoes and again use the immersion blender or a hand mixer to mix the ingredients together.
