Such a gorgeous mixture of flavors. From “Where Cooking Begins” by Carla Lalli Music in Bon Appetite magazine.
3 lb. sweet potatoes. (6 small or 3 large), scrubbed
6 tbsp. unsalted butter, room temperature
¼ cup fresh lime juice
2 tbsp. tahini
1 tbsp. soy sauce
2 tsp. toasted sesame oil
Kosher salt, freshly ground pepper
Flaky sea salt
Toasted sesame seeds and lime wedges (for serving)
Bring a few inches of water to a boil in a medium pot fitted with a steamer basket. Halve the sweet potatoes crosswise if large and place in steamer. Cover, reduce heat to medium, and steam until fork-tender, 25–30 minutes.
Meanwhile, smash together the butter, lime juice, tahini, soy sauce, and sesame oil in a small bowl with a fork until smooth, about 3 minutes.
Season the tahini butter with kosher salt and lots of pepper.
Arrange the sweet potatoes on a platter or a large plate.
Let cool until you can just handle them, then split them open and generously spread the tahini butter over.
Season with sea salt; top liberally with the sesame seeds.
Serve with lime wedges (this dish really comes alive with lots of bright citrus).
