Peel back the husks of the sweet corn, so they point in the opposite direction. Then remove the silky inner strands with a brush.

Preheat the grill on high. Lightly brush each cob with olive oil, and place on the grill with the cobs over the fire and the husks over the front edge to prevent burning. Turn fire down to medium.

Using the husks as handles, turn the corn every two minutes (and switch their places), in order to grill evenly. Once lightly charred – about 12-15 minutes – serve immediately with butter, Sichuan pepper sea salt, and smoked serrano chili powder.
