Grilled mackerel with herbed pearl barley salad Recipe
First make cucumber ketchup. Put 1 cucumber , 1/2 small onion , a tiny piece of peeled ginger , 1 peeled clove of garlic , 1/2 tsp Dyon musterd , 40ml sherry vinegar and 1 tbsp sugar in a blender, puree until smooth, then pour into a large saucepan and bring to a simmer. When the mix starts to bubble, turn down the heat to medium-low and cook, stirring occasionally, for 35-40 minutes, until reduced by a third. Meanwhile, bring a pan of salted water to a boil, then simmer 60g pearl barley according to the packet instructions (up to 50 minutes), until tender. While the barley is cooking, toast 15g sunflower seeds in a dry pan until lightly browned, then tip into a small bowl. Boil 40g samphire for 3 mins and a handful of mini asparagus for 1 min. Once the pearl barley is cooked, drain and empty into a separate bowl, dress with the olive oil and lemon juice, and season. Heat the grill to its highest setting. Season 2 mackerel fillets and rub all over with a little oil.
