Baked Korean Sweet Potatoes With Scallion-Miso Butter 

Korean sweet potatoes are full of surprises: Their gorgeous purple skin reveals not orange but white flesh underneath, which has a floral, honey-like sweetness and a supercreamy texture. (Japanese sweet potatoes can be used interchangeably, and even any supermarket sweet potato variety can be used for this recipe.) Wrap your sweet potatoes tightly in foil and roast until completely soft in the center, about 1 hour. While your oven works, make a quick scallion-and-miso compound butter that complements the sweet potatoes but can also elevate all sorts of roasted veggies like cauliflower, carrots and broccoli. Split open the hot potatoes and dollop with the compound butter and a spoonful of sour cream. Each bite has a wonderful balance of sweet and salty; the addition of sour cream introduces nostalgic sour cream and onion vibes.
