Horse can be a wonderful meat if done right! A lot of people were put off by the so called horsemeat scandal. What bothers me more about unscrupulous meat distributors is the quality of the meat itself (as well as not knowing what you are buying, but if you buy findus lasagnes, what do you expect!). Many of the "horse smugglers" were using chunks of beef several years out of date, cutting putrid meat from them before mincing and bulking out with other meats.
Horse produces wonderful steaks, burgers, stews. When I was a boy, any holiday in France was not complete without a meal of horse. Can be very flavourful, but can also be very dry, sinewy and chewy - depends on the piece you get and how you cook it.
The license to butcher horse in the UK is prohibitively expensive, which, combined with the British public's reluctance to eat it, means it is neigh on impossible (boom! boom!) to find in Blighty.
