I had fried grasshoppers when I was boy. I had heard or read about them
somewhere, and they sounded exotic and appealing. Lo and behold, a small
deli in Kenosha, WI., for God's sake, actually sold little tins of them. I
pestered my mother for months until she finally gave up and bought them for
me. They were crunchy and tasted pretty much like oily ashes. That was a
long time ago, so I'm not really sure, but I like to think I learned
something that day.

Obviously, you need to eat fresher grasshoppers. Come visit me
anytime from late July to mid-September, and you will find about
a bazillion (roughly) grasshoppers in my garden, cheerfully eating
all my veggies down to the ground. If you eat enough of them, I
might even quit spraying them with insecticide.
