Wash and dry the aubergines well.  Remove the stalk carefully, to avoid wasting any of the flesh.  Line a baking sheet with greaseproof paper and arrange the aubergines on it without adding any oil or fat.  Place the tray in a preheated oven, 200°C, for approximately 45 minutes.  

When they come out of the oven, and as they are still hot, use a knife and fork to slice them open.  Discard as many of the seeds as you can (as they may cause indigestion), and scrape and collect the flesh off the skins well.  

Pass the collected flesh of the aubergines through a sieve, and press as much of the juices out as you can.  Transfer the aubergine flesh into a food processor, add the rest of the ingredients and process till smooth.  And you are done!!   (it is not neccesary to use a food processor, as the ingredients can be mashed together using a fork or spoon).
