Bistek-Style Tanigue Steak Recipe

Make the marinade: the juice of the calamansi, sugar and soy sauce. Mix well. Marinate the fish in the calamansi mixture for 10 minutes. 

In a large pan, lay the slices of the fish steak in a pan, add the marinade and let it cook for 10 minutes. Add the butter and season with salt and pepper. 

Add the onion rings and simmer for a few minutes. Serve immediately.
