Salt cod and tomatoes

I really only discovered salt cod when I was sailing in the Caribbean. A West Indian staple and, originally a cheap preservable slave food, it is to be found in the islands in many forms. This recipe - a lovely starter, main course salad or lunchtime snack - is the invention of my sexy Swedish photographer friend Carin, and I love it. Salt fish needs to be soaked overnight in cold water to both remove the excess salt and plump it up a bit.
