Sauté the diced aubergine in olive oil for 8-10 minutes, then add the onion, celery, and ginger, cooking for another 4-5 minutes.
Stir in the curry powder and tomato purée for 2-3 minutes, then add the sugar, vinegar, and 6 tbsp of water, simmering until thickened.
Finish by stirring in the pine nuts, raisins, and fresh coriander.
Prepare the Sardines:
Combine the parmesan, parsley, and breadcrumbs in a bowl.
Dip the butterflied sardines first in flour, then egg, and finally coat with the crumb mixture.
Cook and Serve:
Deep-fry the sardines in batches at 180°C (350°F) for 2-3 minutes until crisp.
Drain on kitchen paper, season with salt, and serve immediately with the room temperature chutney and rocket salad.
