i made duck fat french fries once. i have a taiwanese foodie lady that had a vat..we came up with frying potatoes together..
they were amazing, but i admit, i didnt feel that great afterwards. probably 80% mental.
bear fat is supposed to be crazy good. i helped gut a bear once. my hands have never been so soft. my knife was super dangerous and slippery. me? no thanks..my arteries are choked down enough anyways.
