It was in the early 90's, when my husband and I was into farming a couple of years after we were wed, one of the crops we planted was sweet corn. We did a lot of experimenting until we came up with the best way to boil them. Here's the tip:
Don't boil corn for more than 3 minutes. Place the corn directly into boiling water, and do not add salt. You will find the flavor is much better than cooking for 10 minutes or more. Corn will never get soft, no matter how long you cook it-it will only lose its taste.
