Californian prawn wrap with tomato salsa

Method

1. To make the tortillas, combine the flour, baking powder and salt in a mixing bowl. Rub in the vegetable shortening until the mixture resembles small peas. Add the water slowly and knead until smooth. Cover with a damp tea towel and leave for 15 minutes.

3. Season the prawns and marinade them for 15 minutes in the lime juice and zest, red onion, chilli and parsley.

4. Preheat the oven to 150?C/gas 2. Heat a large griddle pan and add the olive oil. Griddle the prawns on a high heat until cooked. Warm the tortillas in the oven for 5 minutes.

5. Mix together the crème fraîche, coriander and cumin seeds. Season.

6. Spoon a good dollop of the crème fraîche mixture in the middle of each tortilla. Lay 6 prawns on top, a few slices of mango and avocado and wrap up tightly.

8. Serve the wraps with the margarita, some tortilla chips and salsa.
