Prawns with chorizo

Method

1. Preheat the oven to 190°C/ fan170°C/gas 5. Make the croûtes. Cut the brioche into 8 thick squares, measuring 8cm x 3cm, and put on a baking sheet. Drizzle over both the oils and season with a little salt. Bake for 12-15 minutes, turning occasionally, until golden. Remove. Set aside to cool, then store in an airtight container until ready to serve.
2. Make the braised leeks. Cook the leeks in boiling, salted water for 2-3 minutes or until tender. Whisk the garlic, oil, lemon zest and juice and some seasoning together in a shallow, non-metallic dish. Drain the leeks and plunge them immediately in the dressing, turning to coat. Cover and set aside until cool, then chill until ready to serve.
3. Heat a large, heavy-based frying pan over a medium heat. Add the chorizo slices in 1 layer and fry for 2 minutes each side, until golden and crisp. Remove from the pan with a slotted spoon and drain on kitchen paper. Cool, then store in an airtight container until ready to serve.
4. Add the prawns to the chorizo oil left in the frying pan and cook for 2-3 minutes each side, until pink and cooked through. Remove from the pan and allow to cool, then add to the leeks and chill until ready to use.
5. To serve, bring everything up to room temperature. Put a brioche croûte on each plate. Remove the leeks from the dressing and place on top of the croûtes. Layer the prawns and chorizo on top of the leeks, using a wooden skewer to secure. Whisk the herbs into the reserved dressing and spoon over the top and serve.
