Step 1

Lay fish on work surface or plate. Sprinkle on both sides with salt and pepper.

Step 2

Place rice flour in a shallow dish. Dredge the fish in the flour and shake to remove excess.

Step 3

Melt butter in a large skillet in a large heavy skillet over medium-high heat. Add oil and then carefully add fish fillets. Cook, adjusting heat as necessary to prevent the butter from burning. Carefully flip the fish over when it is golden on the bottom, 1 to 3 minutes.

Step 4

Continue cooking until the fish is opaque all the way through, 30 seconds to 2 minutes longer, depending on thickness.

Step 5

Serve immediately with pineapple salsa or transfer to a plate and tent with foil while making the caper sauce.
