The arrow is a full size aluminum hunting arrow with a 90 or 100 grain bullet head that has been drilled at the base for the introduction of a wire barb that is soldered into place. The hole it makes is quite small and the barbs grab the frog and haul him in nicely.
We cook the frog legs on a smoker grill so the fire is about two feet below the cooking surface. You can use a Weber or similar grill. Just build a small fire so it doesn't get too hot. Cover the grilling grate with heavy duty tin foil and poke a bunch of holes into the foil. Put the frog legs on, add the BBQ sauce, and cover them. It takes about fifteen to twenty minutes on the cooker, sometimes less. But, if your having a big problem with them sticking to the foil, your fire is too hot. Make sure you have a lot of frog legs because they are so good you're going to want more.
