Add the corn to boiling water and cook for 3 minutes. Pat dry.
Slather the corn with the miso butter to coat all sides.
Broil the corn in the oven for 3-5 minutes until lightly charred, turning halfway.
Remove from the oven. Garnish with chopped herbs, red onion, sea salt and pepper. Drizzle with lime juice and serve with the remaining miso butter.
