What is a conscientious cashew-lover to do? Sainsbury’s sells Fairtrade cashews (£4.50 for 300g). Other brands to look for are Liberation and Traidcraft. But realistically, only small numbers of consumers will pay more for cashews than they need to. As with dairy farming closer to home, supermarkets should do more to support those whose hard work drives their profits. When we buy sweet, wholesome cashews we don’t want to be colluding in human misery.
