Preheat the oven to 230°c / 450°f.
Cut the aubergine and then toss them in the olive oil and a big pinch of salt. Place the aubergine slices evenly on a large lined or non-stick baking sheet and roast for 20 minutes in the oven.
1.1 kg aubergines, 2 tablespoon olive oil
Remove from the oven and flip the aubergine pieces over and them put back in the oven for another 10 minutes until it starts to brown. It should be perfectly tender once baked.
During the last 10 minutes of the aubergine baking, pour a splash of oil into a large pan and pop over a medium-high heat. Add the onion and cook for 5 minutes until softened and starting to brown. If you cook for longer, until they start to caramelise, the outcome will be better. If you don’t have time, stick with 5 minutes.
1 onion
Next, it’s time for the garlic, ginger, cardamom, cloves and curry leaves. Add to the pan and then fry for a minute until fragrant, stirring continuously. Then add the powdered spices, stir and fry for another minute.
