I decided to up our fish intake in January. It's the only new year resolution I've ever kept. We now eat fish twice a week, sometimes three always at least one oily portion - usually salmon, trout or mackerel.
Google fish curries or fish masala for ideas. That probably best for white fish fillets. You can make kedgeree with flaked smoked mackerel fillets and it's not just a breakfast thing. I've even got into kippers with scrambled eggs and toast for breakfast. They're nice but very smelly.
You can fry or grill fresh mackerel fillets so the skin is crispy and eat them with rice or boiled new potatoes in their skins with some butter and green beans, broccoli or roast tomatoes. Make a sharp sauce to cut through the oiliness by boiling down a tin of rhubarb with some sugar, cinnamon, cloves or maybe some ginger instead and butter. If it's in syrup instead of water don't worry. Just use some of the syrup instead of adding sugar. You want a dollopy consistency like apple or cranberry sauce. It makes about four portions.
Here are some recipes. I don't know how to format them since the MNHQ update but you can probably still see them.
I love this cafedelites.com/easy-honey-garlic-salmon/ but I've learned it works better if you cook the salmon skin side down for a few minutes and then put the honey and soy etc in to let it cook together for a few minutes' more. Skip the keeping-warm-in-the-oven bit and it doesn't need cooking on the other side because the heat will get through and if you try to flip it over you'll probably break it. It's nice with stir-fried noodles and vegetables or rice. The other recipes look good too.
This is also great and you either use just raw frozen prawns or a selection of frozen mixed seafood www.deliciousmagazine.co.uk/recipes/chilli-tomato-and-prawn-pasta/
Best till last - I love www.theguardian.com/lifeandstyle/2007/apr/11/foodanddrink.shoppingand will eat it tonight with trout fillets but you can use any white fish or salmon fillets - skin on or off. You don't have to follow the whole recipe. I always put in grated lemon zest and juice instead of the preserved lemons and though the fennel is nice you can leave it out. If you use it slice it really thinly because it takes a long time to steam. It's very easy to make but seems quite special.
