Trout - cleaned, scaled and gutted but with their heads and tails.
Onions sliced in circles and some finely chopped.
Herbs and seasoning.
Make a strong herbal tisane with two teaspoons in half a cup of boiling water. Allow it to brew. I used a rather nice apple and lemon tisane.
Line a large flat oven-proof dish with foil and oil it. Cover the base of the dish with circles of onion and place the trout on top. Place the finely chopped onion inside the fish with seasoning and herbs. Pour the tisane over the fish including the leaves and fruit. Sprinkle herbs and seasoning over the fish. 'Tent' the foil over the trout and place in a pre-warmed oven at 180•C for 30 minutes. Open the tent and drizzle olive oil on the fish and return to the oven for another ten minutes.
Serve with potatoes and vegetables.. Enjoy!
