Yup, love me some canned biscuit donut holes...
My dad showed me how to make them back in the 70s... It was a staple when I was growing up... My wife thought I was insane the first time she watched me make them, until she tried one and loved them... You should have seen her face the first time I showed her jiffypop...
I use that "just add water" pancake mix for my tempura batter, 1/2 cup pancake mix, 1/2 cup flour, an egg and water to get it pretty loose... I take any type of white fish fillet and cut it into hotdog size, dip them and fry them up... Throw them on a hotdog bun and cover with tartar sauce... I call them fishdogs, everyone that's had them can't get enough...
Also do a tighter batter/dough like your recipe but throw a can of tuna in it and fry up what we call "fish balls"... My kids love them with mayo/ketchup special sauce...
