Hot chillies were being added to bland food in the New World long before the Egyptian pyramids were built. Linda Perry of the Smithsonian Institution found that ancient peppers could be identified from fossilised grains of starch. Such grains were then found alongside remnants of corn, yucca, squash, beans and palm fruit. The oldest were from two sites in Ecuador dating to 6,100 years ago, but the spicy fruit soon spread through South and Centra America (evidence from Peru, Panama, and the Bahamas), before going global with the Spanish conquistadors. The remains of at least 10 varieties of chilli pepper have been found in two caves in Mexico and dated to 1,500 years ago. Science, Independent, 16 Feb; Times, 10 July 2007 Terry W.
