Of course I'm not a good person to ask as I've been vegan for far too many years, but if I remember correctly, the process is very simple. Basically just remove the legs and cut the skin off, then use them like mini chicken legs. This is actually how I was tricked into eating them as a kid, my parents told me they were baby chicken legs 😁. I do remember frog hunting as a teen with a flashlight bucket, and frog gigging pole, basically a mini trident.
Well damn... hahahah I would've cried back then I think, because as kids we don't explore as much with food.
Yeah, I've seen online those legs being fried like fried chicken 🙈.
