Preparation
How to Prepare Corn Before Cooking
Remove husks and silk, then rinse the corn. Break large cobs in half if needed so they fit in the pot.
Fresh corn kernels cut from the cob cook very quickly. They only need to become hot, juicy, and tender.
After boiling, let the cob cool slightly, stand it upright on a cutting board, and slice downward with a sharp knife to remove the kernels.
Keep fresh corn in the husk until close to cooking when possible, because the husk helps protect the kernels.

Types
Sweet Corn vs Field Corn
Most corn sold for eating on the cob is sweet corn. It cooks quickly and should stay juicy.
Field corn is starchier and tougher, and it is not the same as fresh sweet corn. It may need much longer cooking and is usually better for specific traditional preparations, drying, grinding, processing, or animal feed.
Texture
Do Not Overcook Fresh Corn
Fresh sweet corn can be ready in just a few minutes once it goes into boiling water.
Once the kernels are hot, juicy, and tender, remove the cobs from the water instead of letting them sit.
Kernels
Cooking Corn Kernels
Fresh corn kernels cut from the cob usually take only 2 to 5 minutes in boiling water.
Frozen corn kernels also cook quickly. Add them directly to boiling water and drain as soon as they are hot and tender.
Methods
When Another Cooking Method Is Better
Boiling is the easiest method for juicy corn on the cob. Steaming keeps the flavor concentrated and uses less water.
Grilling is better when you want smoky flavor and charred kernels. Roasting gives deeper sweetness, and sauteing is best for corn kernels cut from the cob.
Texture
How to Know When Corn Is Done
Corn is done when the kernels look plump and taste sweet, juicy, and tender.
If the kernels become wrinkled, chewy, dull, or starchy, the corn may be overcooked or too old. Fresh sweet corn loses its best texture if boiled too long.
Flavor
Best Seasonings for Corn
Classic corn seasonings include butter, salt after cooking, black pepper, parsley, chives, and a little lemon or lime.
For stronger flavors, use chili powder, paprika, cayenne, hot sauce, cilantro, basil, dill, thyme, tarragon, mayonnaise, sour cream, Parmesan, cotija, feta, or lime.

Common Mistakes

- Starting sweet corn in cold water and cooking it slowly.
- Leaving cooked corn sitting in hot water.
- Adding too much salt before tasting.
- Not removing all the silk before cooking.
- Cooking loose kernels as long as whole cobs.
- Assuming old corn will become sweet and tender just by boiling longer.
