This elegant spring onion crusted arctic char offers a simple yet sophisticated way to enjoy sustainably sourced fish. Part of the salmon family, arctic char has a delicate, buttery texture that pairs beautifully with the sharp, savoury notes of grilled spring onions. By using a small amount of mayonnaise to bind the topping, the fish remains incredibly moist under the heat of the grill, resulting in a golden, slightly charred finish that feels much more indulgent than it is.
