I don't think I mentioned it here, but while I was in Paris I got the chance to go to a five-hour cookery class which took a small group of us (five, on this occasion) around the market, learning about the different shops and how to spot the freshest and best produce. Then we decided on a four-course menu based on what was in season - including, naturally, a cheese course - and took it all back to the cookery school to cook it.
