Heat your oven to 200C (390F) and line a baking tray with baking parchment.
Wash and dry your aubergine, cut in half lengthways, prick all over, then place onto the baking tray in the centre of the oven.
Bake for around 35 minutes, until the aubergine is really soft.
Remove from the oven, and carefully remove the flesh from the skin.
Place the aubergine flesh into the bowl of your food processor, along with the other ingredients, barring the oil, and whizz for a couple of minutes, until you have a semi-smooth paste.
Decant into a suitable dish or plate, and drizzle the oil over the top.
