I've just made a big pot of caponata, following the Ottolenghi recipe (it's online). I let it mature for a couple of days and we're having it with some crusty bread this evening. I did include a chopped courgette and I left out the raisins (I don't care for them at all in savoury things such as kofkas and pasta con le sarde). It tastes very promising. The aubergines don't half soak up the oil, and if we find it a bit oily I'll use a different method next time. Jamie Oliver's recipe is much-praised and it's easier to do, though, oddly, he leaves out the celery, which would make many a Sicilian hopping mad...
