Prepare the fish as usual - salt and pepper inside and out and massage in the olive oil. Spread the sprigs of herbs on a baking sheet and place the fish on top.
Put in the oven and bake for about 20 minutes. Brush with olive oil every now and then.
After baking, light the twigs and serve the fish burning on the baking sheet. But be careful - it can allegedly lead to deflagrations, so that glowing particles fly through the air (but this has never happened to me!)
