1 spring onion, finely chopped
1 teaspoon grated fresh ginger
finely grated zest 1 lime
1 clove garlic, crushed

After the crayfish has been put to sleep, use a large kitchen knife to split the crayfish in half lengthwise.
Season the flesh side and lightly brush with the miso butter.
Place flesh side down on the barbecue grill and cook for 2-3 minutes. Turnover and spread with the remaining butter. Cook for about another 5 minutes, or until tender and cooked through.
