Another Nigella Lawson recipe!
So I did a bit of googling...
First up, an interesting one from Steve Manfredi - he uses it as a bed for a nice piece of roast murray cod - looks, yum.
Unlike Nigella's, both Manfredi's recipe and this one include some butter and parmesan cheese, not surprising since we all very accustomed to pairing spinach with cheese (think gozleme, aspanakopita or a spinach quiche).
Even though I've always thought of it as Italian, I also found this 'tapas' (so I guess Spanish version), this is a particularly speedy recipe and it includes paprika this time (that's the spanish touch?) and uses raisins rather than sultanas. Sultanas are nice and plump, but the smaller raisins can be more intense.
And finally here's another variation on the theme which includes broccolini and, at last, bacon (or pancetta). Interestingly, this one also has a classic italian salad dressing of oil, balsamic vinegar and lemon juice.
Anyway, I think that makes the point about the flexibility and usefulness of some of these basic combinations. Try it a few times and then you can vary it as the mood and availabiltiy of ingredients dictates.
