Gochujang is the hard stop: Harris Teeter carries it reliably, but Food Lion, Walmart, and ALDI do not stock it consistently, forcing a second trip or substitution on a weeknight. Miso paste, similarly, is a specialty ingredient that most standard Harris Teeter locations have, but not every Kroger banner or Food Lion will. The other ingredients are universally available, and corn is cheap and in season through late summer in North Carolina. The sticker is that this is genuinely a 30-minute dish only if you're grilling ahead of time—shucking eight ears adds 10 minutes minimum, and charring them on a grill or cast iron takes another 15. Budget the specialty condiment run or plan this when you already have gochujang on hand, and it becomes a crowd-pleasing side that leftovers actually improve as the miso-chili flavor deepens overnight.
