Makes 1 (serves 2)
1. Spoon coriander and cumin seeds into a frying pan and toast over medium heat for 3-5 minutes until fragrant. Tip into a mortar and use pestle to finely grind the warm spices.
2. Cover base of frying pan with olive oil and add shallots and garlic, cook over low heat until soft and translucent. Spoon into a bowl and refrigerate until cold. Wash coriander root well then finely chop 6cm of the root and stem, set top half of the bunch aside for later.
3. Combine mince, lemon rind, egg, breadcrumbs, mustard, shallot and garlic mixture, spices and salt and pepper in a bowl. Use clean hands to mix until well combined. Preheat oven grill to medium-high.
4. Press beef mixture onto a 22cm round flat bread, leaving a 1cm border around the outer edge. Heat a little oil in an ovenproof frying pan over medium heat, add pita bread and cook 1 minute. Transfer the pan to the oven and grill 4-5 minutes until just cooked through. Remove from the oven. Check the under-side of the bread is golden and crisp if not cook a few minutes on the stove top over high heat.
5. Meanwhile, finely slice the onion into a bowl using a mandolin. Season with salt and drizzle with extra virgin olive oil. Thinly slice the cucumbers on the angle and place into a bowl. Season with salt and drizzle with extra virgin olive oil.
6. Remove the kofta from the pan. Spread generously with yoghurt. Top with onion salad, cucumber, coriander sprigs and deep fried shallots to serve.
