Roasted Japanese Sweet Potatoes with Scallion ButterMarcus Nilsson
If you've never had pale-fleshed Japanese sweet potatoes before, you'll be surprised by their subtler, drier flesh, which tastes unmistakably of chestnut. A bit of miso mixed into the scallion butter stealthily rounds out the interplay of sweet and umami that will have you eating all the way through to the last flaky remnants of skin.
Cooks' notes:
· Scallion butter can be made 4 days ahead and chilled, covered. Bring to warm room temperature and stir before using.
· Sweet potatoes can be roasted (but not cut) 4 hours ahead and kept at room temperature, covered with foil. Reheat potatoes on a baking sheet on middle rack of a 350°F oven until heated through, about 20 minutes.
