You can use any fish for this recipe, my local fish shop had plaice, so that was what I used.
For the sauce you will need to soak almonds overnight and the next day peel off the skins. Soak a few (one or two per person) dried tomatoes for at least half an hour in water. Place both in a blender with a pinch of salt and half a teaspoon of dried garlic powder. Add enough water to enable blending into a smooth paste (or chunky, if you like that better). Adjust salt.
Place plaice (pun!) in a greased baking dish, spread sauce on top and bake about 20 minutes on 200°C, the crust should get a bit browned. Serve with a grain or (for easier digestion) with steamed vegetables, preferably leafy greens. I had curly cabbage, string beans and cauliflower leaves. Raw daikon with a drop of tamari soy sauce and some finely chopped spring onion will help to digest the fish and oils as well.
