Well I managed to catch enough crickets to be worth while. And a few locusts too.
I've read that you should give them a quick boil in water for 2 minutes to kill any parasites they may have, then pluck off the wings, legs and antennas, then you can roast them and even grind them into a flour.
I think for my first go of it I'm gonna make potato, zucchini, cricket skewers with the veggies and crickets I have on hand. I still have to find a way to catch more crickets and more efficiently. I'm gonna try a few homemade traps.
I might as well, the fields here are full of them chirping this time of year.
