Supermarkets sell cleaned, prepared cobs of corn. If I pick my corn from the plant, which parts are there, and how are they cleaned?

1 Answer 1


Corn has husk, silk and kernels. In the middle there is the cob, which only becomes visible after you have eaten the kernels.

enter image description here

The husk is, botanically speaking, formed of leaves, but it has a different texture from the standard leaves and encloses the cob with the kernels snugly. It can be left on the cob during boiling, or removed before boiling. For grilling and other preparations, remove the husk. It is not edible, historically it was used for crafting. In the kitchen, it can be used for wrapping a tamale, although wider leaflike matter is more convenient, if available (such as banana leaves).

The silk is called that because it looks and feels like silk while young. The silk in ripe corn tends to be sun dried and brittle, at least outside of the "package" of husk. It is not usually eaten. See also Tips for Removing Silk from Corn?.

The kernels are what you want to eat. Most methods call for preparing them while still on the cob. If you need them removed, you can "shave them off" the cob with a sharp knife.

The cob itself is the dry semihard thing in the center. It has no culinary uses.

The leaves are used to feed livestock, but not eaten by humans.

An ear is the name for the whole package you pick off the plant, so the kernels on the cob with their silk and husk.

The stalk is something not generally seen in a kitchen. It is thick and tall, supporting the leaves and the ears.

  • I'm glad I could help! Also, now that I checked, it seems that I made a mistake - I thought the husk was made from sepals, but it turns out it is a special kind of leaf after all. Anyway, when corn is used by humans, the husk and leaves are handled separately.

  • if you're going to mention the leaves, you might want to mention the stalk for completeness.

  • @Joe The leaves were in there to help people learn to distinguish them from the husk, so they can use proper terminology in the kitchen. But OK, added the stalk too.

  • I think you are mistaking by saying the cob has no use it is used to put fire that is it can replace wood in cooking Commented Jun 16, 2020 at 16:34
