If you're adding corn from a cob, place the cob into the microwave (husk on) and cook for 3 minutes. Using oven mitts, remove the cob. Cut the end off and squeeze—the cob should slide right out. You can cut down the cob with a knife to release the kernels now, or pop it onto a grill pan for a few minutes to get that char flavor, and then cut the kernels off.
