yep panko. I only cook at 325 to 350 though as panko will burn easy. Mix whatever spices you want in flour and set in a shaker or dish. I Like chili powder johnny's season salt, garlic powder, old bay, or just salt and pepper.
Dust finger sized pieces in flour, dip in egg wash, shake in panko and fry up at 350 for 2 min or less.
This is how I fry fish for fish tacos. Super crunchy. a good sauce is...
1/2 cup sour cream
1/2 cup real mayo
1/2 lemon squeezed
3 to 4 canned chipotles and a spoonful or two of abodo sauce.
pinch of good salt.
Throw in a blender and you have made pink chile mayo/ tar tar sauce.
