This is my wife's way to cook frog legs, very simple method. The frogs we get are locally harvested here in the village, they are not big but they are delicious. We get whole, cleaned, skinned frogs, I use the legs, the rest of the frog goes to the family and they use those to make a spicy Thai dish. This is a low ingredient recipe that makes a great meal. This is a make as much as you want recipe.
I paid 300 Baht for the 15 frogs, and with the legs we cooked and the rest of the frogs cooked by the rest of the family, this provided about 10 servings. Plus I have some legs left over for dinner another day. This works out to about 90 cents per serving overall.
