The way food looks affects very much how it tastes. In the world of apples, individuals seem to have a strong preference for certain colours and textures.
Today’s invention is a domestic spray paint booth for repainting apples of one colour in a different shade/pattern. If you don’t fancy those Golden Delicious in their uniform yellow skins, drop one in the spray unit and it will emerge a moment later automatically coated in reddish blotches more redolent of a Braeburn.
The sprays (based on digestible food colourings) could of course be adapted to contain extra flavours (to encourage children) or take the form of trademarks for use in corporate events. With any luck, this might also stop apples having those annoying little sticky labels attached.
