Ginger-soy-lime marinated prawns

1)Use a citrus press attachment fitted inside a food processor to juice your limes, or squeeze your limes by hand.

2)Place shallots, ginger, garlic, soy, lime juice, and sugar in a blender and blend until smooth.

3)Add the spring onion and oil and blend until combined. Season with black pepper, to taste.

4)Place prawns in a large bowl, pour the marinade over, and marinate at room temperature for 20 minutes.

5)Preheat a grill to high. Remove prawns from the marinade and grill for 1 1/2 to 2 minutes each side. Serve on brown paper bags, if desired.
