I have a fresh-frozen trout, headless and gutted. The fish is thawed at room temperature, cleaned of scales, the fins are cut off. Trout is cut into portions and seasoned with salt, lemon juice and spices. My spices include mint, marjoram, French rosemary and herbs, you can use spices for fish already in a ready-made package or whatever you like.
Leave on the table for 20 minutes.
