It can seem frustrating to try a new recipe and not know how much of an ingredient to purchase at the store. Sometimes they call for "1 cup of corn kernels" or "the kernels from two ears of corn". That's a fine description if you are using frozen corn or fresh corn respectively, but otherwise, exactly how much corn is on an ear of corn? In order to help make cooking easier we did some experiments to help tell you exactly how much corn you need to buy.
To answer How many ears of corn kernels make a cup we went to the grocery store to check out the produce section. When talking about sweet corn, a small ear tends to measure less than 6.5 inches long and a large ear more than 7.5 inches. Therefore, a medium ear usually falls somewhere between 6.5 and 7.5 inches long and 2 inches across at the widest point. For our test samples we purchased medium ears of corn and headed home to the kitchen.
To answer the question How much corn is on an ear we removed the kernels from medium ears of fresh corn. While the yield of the corn kernels will obviously vary by the size of the cob, it was surprising to see a heavy 1/2 cup to a 3/4 cup result range within the "medium" size corn cobs. More often than not, our medium ears of corn produced 3/4 cup of kernels when cut from the cob.
So if your recipe calls for 2 ears of corn, you can now confidently know that it means about 1.5 cups of corn kernels. And "How many ears of corn do you need for 1 cup of corn kernels" is about 1 and a third ears of corn.
Did you know that corn is technically a grain, not a vegetable; it is a cereal crop that is part of the grass family. The ear is really part of the corn flower and each kernel is a seed. Corn will always have an even number of rows on each cob. Popcorn is a special type of corn grown that when heated it bursts into hot, fluffy kernels - yum! And corn is used to produce fuel alcohol which makes gasoline burn cleaner, reducing air and water pollution.
