Turn your oven broiler on to its highest setting
Place prawns in a mixing bowl and add saffron powder, water, paprika, salt, turmeric powder and a few glugs of olive oil;
Mix to combine;
Allow prawns to rest in the marinade for 20 minutes;
Thread prawns onto skewers and place on a baking tray;
Place under the broiler for 5 minutes per side (unless your hands are made of asbestos like mine, to easily flip the prawns without burning your fingers, use kitchen tongs). Keep a steady eye on the prawns as each broiler's heat intensity varies and therefore the cooking time may vary, too.
Mix 2 tsp paprika with a tablespoon or more of olive oil to serve on the side and drizzle on the prawns at the table
Serve prawns atop garlic-scallion rice
