Because mackerel is found all over the world, in both tropical and cold waters virtually every cuisine is a method of cooking mackerel. One of the best curries I ever ate was a Goan mackerel curry. Since then I have eaten it in Japanese and Korean restaurants and one of my favourite ways of eating it is simply with a plum sauce and spring greens. The recipe is below


Serving mackerel

you can cook mackerel in a variety of ways, it can be cooked whole which is generally my preference. However, I do understand people who freak out when they find fish has a head on it. You can always ask your fishmonger to fillet it for you!They are pretty easy to fillet yourself with a sharp knife.
I generally either steam the fish or I grill it or sometimes pan fry just with two drops of sesame oil. It is an oily fish does not need to be drowned in olive oil. The plum sauce may sound overly complicated. If you can’t get Japanese plums by plums in natural juices. The balance should be between salty and sweet flavours. If you can’t find rice vinegar then use a simple white wine vinegar. You toast the sesame seeds by putting them in a dry pan for about 40 seconds until they turn brown.

Baked Mackerel with Vine Tomatoes

This is a more robust way of serving mackerel. Now when I lived in Spain in Andalucia for very nearly 30 years. The Spanish mackerel is not as meaty or as oily as its British counterpart and consequently it didn’t stand up as well to serving on its own grilled. However, this method I used to cook it was fabulous especially when served with last night’s roast vegetables. Baked Mackerel Spanish Style

Mackerel is packed with good healthy fats. It is tasty and filling and best of all it takes lots of other very pungent flavours such as the Japanese wasabi paste or horseradish. This makes it a great supper just horseradish and grill mackerel or even smoked mackerel. Other benefits of eating mackerel is the fact it cooks very quickly in five minutes it is cooked.
