Oily Fish ... did you know !
CJ Jackson writes for BBC Food, she is also in the team at the Billingsgate Seafood School which is "a charitable company with the aim of promoting the awareness of fish in young people and to increase the knowledge of those people already working in the industry, in areas such as retail and catering. All commercial activities undertaken by the school will fund courses for school children free of charge."
About oily fish she writes:
" Oil-rich fish (or oily fish) are those that have oil distributed through their body, as opposed to white fish, whose main concentration of oils is located in the liver. Although oily fish contain higher levels of oil, they are an essential part of a healthy diet due to the presence of the fatty acid, long-chain omega-3. Oil-rich species include the mackerel and tuna group, herring and anchovy group, as well as salmon and trout. The most sustainable varieties of oily fish are mackerel, pilchards, sardines, herring and skipjack tuna (usually sold canned).

Buyer's guide:
In most cases, fresh is best when it comes to choosing oil-rich fish species because the natural fats occurring in these fish deteriorate and they lose their quality quickly. Oily fish tend to be landed and sold un-gutted to maintain their quality. They’re generally also good value for money. Look for fish that are still stiff and rigid and in ‘rigor mortis’ – this will indicate that the fish has been out of the water for no more than a day or so. At this stage the fish will have bright, clear eyes, the gills will be a vibrant, red colour and it will hardly have any smell at all. As the fish loses condition it will become softer and its smell will become stronger.
Storage:
Oily fish must be stored in as cool a place as possible and eaten quickly, ideally on the day of purchase. Arrange it in a single layer on a tray and keep cool by covering the fish with ice. Oil-rich species freeze well for a short period of time: gut or fillet them, pack into freezer bags as whole fish (or two portions at a time), extract the air and secure the bag. Defrost the fish for a few hours in the fridge before use.
Preparation:
Oily fish are versatile. They suit grilling, barbecuing, roasting and baking and, in some cases, pan-frying. The natural oils give these fish an intense flavour that pairs well with other strong flavours.
Oily fish can also be successfully preserved - smoking, brining and salting are all popular preserving methods. Mackerel is available both hot-smoked and salted; tuna and mackerel are both sold canned too. Herrings can be smoked or transformed into rollmops; anchovies are salted and brined. Salmon and trout can both be hot or cold-smoked.
Other considerations:
Omega-3 is reported to be essential for maintaining good health and preventing diseases in old-age. It's also important for brain development in young children. However, the Food Standards Agency advises a limit to the quantity of oily fish that we should eat because these fish contain more mercury than other types of fish. The FSA recommends that girls and women who might have a baby one day, and women who are pregnant or breastfeeding eat up to two portions of oily fish per week. Other women, men and boys can eat up to four portions of oily fish a week. In addition, marlin, shark and swordfish are not recommended for consumption by boys or girls under 16 or by pregnant women or women who may wish to become pregnant."

Mackerel on toast with salted cucumber and horseradish
A combination of fresh mackerel, pungent horseradish and refreshing cucumber can make a nice start to any meal ... or could even make a light lunch!
Ingredients:
Ingredients:
Serves Four
½ cucumber, peeled, thinly sliced on a mandoline
salt
4 tbsp grated fresh horseradish*
2 heaped tablespoons crème fraiche
2 tsp English mustard powder
4 fresh mackerel fillets
salt and freshly ground black pepper
knob of butter
½ cucumber, peeled, thinly sliced on a mandoline
salt
4 tbsp grated fresh horseradish*
2 heaped tablespoons crème fraiche
2 tsp English mustard powder
4 fresh mackerel fillets
salt and freshly ground black pepper
knob of butter
To serve:
4 slices low carb bread (or soda bread), toasted, buttered
1 small red onion, thinly sliced
½ small lemon
Method:
4 slices low carb bread (or soda bread), toasted, buttered
1 small red onion, thinly sliced
½ small lemon
Method:
1. For the salted cucumber, place the cucumber slices into a colander and sprinkle with plenty of salt. Mix well and leave the contents to drain over the sink for half an hour.
2. Rinse the salt off the cucumber with cold water, then leave to drain. Gently wring out any excess moisture from the cucumber with your hands, then set aside.
3. In a clean bowl, mix the horseradish with the crème fraîche and mustard powder, making sure the mustard powder is well combined with no lumps. Set aside.
4. Season the mackerel fillets on their skin side with salt and freshly ground black pepper.
5. Heat the butter in a frying pan until it is foaming, then add the fillets skin-side down. Place a heat-proof plate onto the cooking fillets, as this will make sure they stay flat and cook evenly. Cook for 4-5 minutes, or until nearly cooked through, then turn the fillets and cook for 30 seconds, or until just cooked through.
6. To serve, place a small handful of the cucumber onto the toast. Place the cooked mackerel fillets onto the cucumber. Place a dollop of the horseradish sauce on top and garnish with a little of the sliced red onion and a squeeze of lemon.

* Fresh horseradish is difficult to source, try a good farmers' market. Otherwise consider using a ready made horseradish sauce, being careful to check carb/sugar content.
