8 small sweet potatoes (about 3 lb. total), scrubbed, halved lengthwise
½ cup extra-virgin olive oil, divided
Kosher salt
6 Tbsp. unsalted butter, room temperature (so the hot sauce can be easily incorporated)
2 Tbsp. honey
3 Tbsp. hot sauce (such as Tapatío or Cholula)
¼ cup raw pumpkin seeds (pepitas)
1 Tbsp. ground coriander
Flaky sea salt
Lime wedges (for serving)
Place a rack in middle of oven; preheat to 425°.
Place sweet potatoes on a rimmed baking sheet, drizzle with ¼ cup oil, and season with kosher salt. Turn to coat. Arrange cut side down and roast until tender (the tip of a knife should slide easily into flesh) and cut sides are browned, 25–30 minutes.
Meanwhile, smash together butter and honey in a small bowl with a fork until smooth. Add hot sauce a tablespoonful at a time, blending well after each addition. Season hot honey butter with kosher salt.
Cook pumpkin seeds and remaining ¼ cup oil in a small skillet over medium heat, stirring often, until pumpkin seeds are golden brown, about 4 minutes. Remove from heat and stir in coriander; season with kosher salt.
Arrange sweet potatoes on a platter and spread with hot honey butter. Sprinkle with sea salt and spoon pumpkin seed oil over. Serve with lime wedges for squeezing over.
Do Ahead: Hot honey butter can be made 1 week ahead. Cover and chill. Bring to room temperature before using.
