Isn't the corn grown for popcorn different from other corn typically grown to grind for traditional cooking uses?
There are many different types of corn, but those commonly grown for food fall under one of these five categories:Flour Corn
Because of its soft, starchy, yellow kernels it is one of the only corns that can be ground into a fine flour. The rest make a coarse sort of cornmeal.Flint Corn
Sometimes called "Indian Corn", it comes in a wide range of colors. Because its kernels are covered in a hard shell, it preserves well as an ornament, however it is also edible when ground into cornmeal.Dent Corn
This is a high yield, yellow or white corn, characterized by a dent in the top of each kernel. It is a popular American agricultural crop used for animal feed, industry, and some human foods, as well.Sweet Corn
This corn can be yellow or white and is often eaten fresh like a vegetable. On the cob or canned, sweet corn's high sugar content makes it very palatable. This is the kind of corn that is commonly grown in home gardens.Pop Corn
Its kernels can be yellow or white and have a soft, starchy center covered by a hard shell. When heated, the center expands until it explodes from its shell, making what we call popcorn. But you can also grind it into meal or flour. Popcorn pollen if crossed into other types of corn cause the next generation to be popcorn.. not good popcorn generally, but popcorn. Shoepeg Corn
Shoepeg corn is a cultivar of white sweetcorn valued for its sweetness. It is characterized by small, narrow kernels tightly and unevenly packed on the cob. The corn has a sweet, mild flavor. The only variety of shoepeg corn available today is "Country Gentleman".
