Ingredients
2 whole mackerel, butterflied or 4 fillets1 tbsp of groundnut or veg oil
3 raw or cooked beetroot cut into wedges
2 eating apple (used granny smith for this but any variety is fine)
1 small fennel, sliced very thinly lengthways
1 juice of a lemon
5 tbsps of extra virgin oil
Cornish Sea Salt Flakes
Pepper to season
4 tbsps of horseradish
6 tbsps of creme fraiche
Cornish Sea Salt & Peppery
5/6 sprigs of tarragon, leaves removed and very finely chopped
1 juice of lemons
1 garlic clove, finely chopped
Instructions
To butterfly the mackerel cut the head off and cut all the way along from the belly to the tail. Remove the spine, easiest way is to use some scissors. Remove as many pin bones as possible. Alternatively, ask your fishmonger to butterfly them for you!
Meanwhile prepare the salad. Either buy cooked beetroot or roast/boil whole beetroot and then remove skin, which comes off easily once cooked. Cut into wedges. Prepare apples by coring and cutting into cubes. Cut the fennel in half and then thinly slice lengthways or preferable use a mandolin.
Toss the fennel, apples and beetroot in the lemon, extra virgin oil and season with some cracked pepper and Cornish Sea Salt Flakes.
Finely chop the tarragon leaves and any fennel throngs if you have any, and mix the extra virgin oil, juice of a lemon and finely chopped garlic clove. Season with a pinch of Cornish Sea Salt and peppery.
For the creamed horseradish, mix the creme fraiche and horseradish together and season with come Cornish Sea Salt Flakes and cracked pepper.
Once you are ready to serve whack your grill to the highest setting and place the mackerel skin side up onto a tray making sure you butterfly it out. Brush with the skin with some vegetable or groundnut oil and season with some Cornish sea salt. The mackerel cooks very quickly so 5-8 mins max under the grill, the skin should start blistering and the underneath steams, do not turn. Once cooked assemble your dish by placing all your salad onto the plate, add the mackerel, dot the creamed horseradish and drizzle over the tarragon oil.
