Method to prepare keralas spicy grilled prawns.
Slice the chillies in half, scraping out the seeds if you want a milder spice mixture.
Put the chillies into a blender or food processor with the garlic, the ginger thinly sliced, the peppercorns, cumin seed, turmeric, coriander seed and creamed coconut. Blitz to a thick mush, adding a little water or yoghurt until you have a loose paste. Scrape into a medium sized bowl.
Rinse and dry the prawns then toss them in the masala paste and set aside for an hour or so. During this time the prawns will take up some of the flavours from the masala.
Get an overhead grill hot. Thread the prawns, three or four at a time, onto skewers, a bit messy this, but it makes the prawns much easier to turn.
Cook them under the grill (or on a griddle) for a couple of minutes until they are sizzling and fully opaque.
Serve keralas spicy grilled prawns, with a little chopped coriander leaves and lime juice.
