I think that shopping for food as close as possible to where it is bred or grown and/or in a retail outlet where the owners can give you chapter and verse on the provenance of all the items they stock is an eminently sensible idea. The Waterfall Farm shop is a place that melds the close to source ideal, as it sells lamb from Waterfall Farm direct to the public, with the wished for good product knowledge as the owners are totally au fait with the origin and other details of the hand-picked range of mainly artisan foods that they sell.
