Keep it simple: one ear of corn = about ½ to ⅔ cup of kernels. Remember this, and you’ll never overbuy or undercook again. You’ll be the person who shows up at the picnic with exactly the right amount of corn salad, and when someone asks, “How did you know how many ears to bring?” you can just smile and say, “Oh, I did the math.”
Corn is one of those joyful, golden ingredients that makes summer taste like sunshine. Don’t let a simple measurement question steal that joy. Now go forth, shuck some cobs, and measure with confidence. Your next barbecue, chowder, or salsa will thank you—and so will your belly.
