Try Alligator and Ox-Tail (Jamaican style) some time at a restaurant that knows how to cook them properly.
Frog legs? Meh. Not horrible but a bit in the weird category. Same with Cow's Feet.
It's the preparation, seasoning and cooking that determines the taste
skirt steak used to be a tough but cheap cut of meat, until fajitas became popular
brisket was a cheap cut of meat until BBQ became popular
ribs used to be cheap until BBQ ribs became popular
chicken wings used to be cheap, until Buffalo wings became popular
I grew up on a farm and we butchered a steer and several hogs every year. Any cut of meat that wasn't a steak, or roast, or ham, became hamburger or sausage. The feet, tail, ect ... were items the dog got for being a "good boy"
I've had Frog legs, Ok, not great, gamey
Never had alligator, would try
Beef or Pork Testicles are excellent deep fried
Liver and Onions are excellent fried
Brains, never tried
Tripas (fried Intestines) are a very popular Mexican Item, that I avoid, but bratwurst which are Intestines stuffed with sausage are excellent!
Soul food uses a lot of the very cheap cuts, which can be very good depending on the preparation and the seasoning. Been a while since I had any soul food though, would have to go to Houston to find a soul food restaurant, and that is 350 miles away
I remember we shot a Mud duck once, cooked it, terrible, gave it to the dog
Quail and Pheasant are excellent! But a lot of that is because by hunting season they have been eating nothing but grain for a couple months ( mechanical harvesters leave about 10 to 15% of the grain on the ground, hence very well fed birds )
having fried cat fish and fried potato wedges this evening
no corn on the cob though
