Chef's tips
Make sure your cast-iron skillet is very hot so the spices char quickly without drying out the fish. Fresh Gulf grouper tastes best, but any firm white fish will work.
Storage
Best eaten fresh; store leftover fillets separately from bun up to 1 day.
Reheating
Reheat fish gently in a skillet to avoid drying it out.
Common mistakes to avoid
- β’Not heating the skillet enough, which stops the spices from charring properly
- β’Cooking the fish too long, which makes it dry
