You can catch grasshopper from the garden in warmer area but it is not advisable as they may have been pesticide-contaminated. They can be easily bought from pet stores. Freeze-dried, ready to cook versions are already available for online purchases.
To prepare them for cooking, live grasshoppers are first dropped into boiling water briefly to kill them, then taken out, allow to drain and cool off. For later consumption, either oven-dried, sun-dried or freeze-dried are recommended. For immediate preparation, the legs and heads are sometimes removed just prior to further cooking, some people prefer to leave them on and let the diners decide whether to eat the whole critters or just the torsos.
