At the back of my fridge you’ll find a jar or two of pickled herring from Ikea. I always stock up when I go, it’s the highlight of the trip.I get excited about any food that is cured, pickled, smoked, preserved or fermented and although I don’t need to travel across the desert with nothing but a camel and a bag of dried meat for company, taking a fresh ingredient and through salt or smoke or just air, turning it into something longer lasting makes me feel manly, much like standing around a barbeque.There is a sharpness to pickled fish that really gives it a zing. Here, I’ve gone for grey mullet rather than the more traditional herring, for the simple reason that my fishmonger didn’t have any. And it was a great success. The radish and cucumber give a great crunch and a slightly Asian feel to the dish and the dill brings it back to its Swedish beginnings.Serves: 4 as a starterPreparation time: 10 minutes plus curingCooking time: curing and pickling onlyIngredientsFor the pickled radish:16 radishes, sliced as thinly as possible2cm cucumber, sliced as thinly as possible1 head of Shimeji mushrooms, sliced from the base or 100g button mushrooms25g xylitol or stevia powder70ml cider vinegar1 tbsp Mirin2 tsp Japanese rice wineA few sprigs of mustard cress1tsp toasted cumin seedsFor the mullet:2 mullet fillets (400g)1 small bunch of dill, chopped1 shallot, sliced1tbsp juniper berries, slightly crushed1tbsp pink peppercorns, slightly crushed1tsp Szechuan peppercorns25g salt25g xylitol or truvia sugar substitute4 tsp caviar/lumpfish roeMethod1.
