Here in the UK, I've got two main sources of tomatoes: supermarkets, or the local once-a-week farmers' market.<p>At the supermarket, they tend to be packaged. At the farmers' market, they're on display loose or on the vine.<p>I don't buy by colour: I buy by <i>smell</i>. No kidding -- the tomatoes on the vine bought from the speciality farm stall smell <i>utterly different</i> to the supermarket variety; a pungent, 'green' scent that you can pick up by sniffing the vine. The supermarket variety, even vines of tomatoes, barely smell at all when you get them out of the packaging.<p>And smell is a major component of the human sense of taste, conveying many of the nuances of flavour.<p>Is supermarket over-packaging actually an attempt to disguise the lack of aroma of foodstuffs by forcing customers to evaluate by sight rather than by the more obviously applicable sense?
