1) For the chilli cocktail sauce, combine the first seven ingredients in a bowl and season with pepper, to taste. Refrigerate until ready to use.
2) For the griddled prawns, preheat a griddle pan or griddle to a medium-high heat.
3) Dress the prawns with extra-virgin olive oil, salt and pepper, to taste, and smoked paprika. Skewer the prawns onto metal skewers, to ease in turning them.
4) Griddle until the prawns are opaque and firm, about 7 to 8 minutes.
Pile the prawns onto a serving platter and drizzle with the sauce or pass the sauce at the table. Sprinkle the parsley over the prawns.
