Note: When you get the corn, don't shuck it until you're ready to use it. For "cutting corn off the cob" all you need are a sharp knife and a cutting board.
Take a fresh corn cob and hold it upright, the bottom pushing against the cutting board.
Use the sharp knife and make long downward strokes on the cob, separating the kernels from the cob.
Rotate the cob and repeat until all the kernels are cut.
Now it's ready to use.
