Corn season in India brings also street carts piled with ears and a small stove — fresh grilled corn, rubbed with a wedge of lime dipped in red chilli powder and salt is an indelible flavor memory. Yum. (I make it stovetop when the pile of summer corn finally arrives.)
On a different note, if you like corn pudding or souffle, you might like corn sformato too.
Re: Step 2… Just do the onion in the EVOO with a pinch of kosher salt over medium low heat until caramelized… while roasting the garlic, tomatoes, and chile. Then add everything to the skillet and continue.
