I'm a good cook and know my foodstuffs. I'm quite a sensible, well educated person on the whole, but get me in the butchers shop and I seem to go to pieces. I'm always hearing the TV chefs banging on about ask your butcher to bone stuff, get stuff for you, tell you where stuff comes from. I just can't seem to assert myself and slink off with 500g mince and a pork pie. Am I the only one who goes to the supermarket for meat, not through choice, but in desperation?
