Begin with peeling and cleaning out all the silk. Leave a short bit of the husk at the base as a handle, it comes handy when holding the bhutta.
Lay the corn directly across the burner on medium heat and let is sit 30-45 seconds before you start rotating.
You are looking for uneven patchy charring, some kernel golden, some deep brown, a few at the tips almost black.
Don't be alarmed with the dar black spots, the char is where the smoky sweetness lives. Keep rotating for 5 to 8 minutes, until the whole corn on the cob is blistered.
Then apply the melted butter using a brush, followed by a spice dipped lemon. Dip the cut face of the lemon half directly into the spice mix and press firmly against the hot cob, rubbed in short quick stores while the sizzle is still happening. Eat right away with a hot cup of masala chai.
