CD. the humble pressure cooker is a useful bit of kit that even puts you in touch with saving the planet mode as it is a fuel friendly device. for batch production of the said chicken stock or the quick rendering of 'nearly' the last juices from the lamb shanks it cannot be bettered. The 'nearly' though refers to the ultimate for such a task. this is the earthenware saltglaze stewpot which was placed in the side oven of the fireplace. Its thick clay walls evened out any variation in oven temperature due to stoking the fire over the long days cooking period.The result after perhaps 16 hours slow cooking was out of this world.
When I worked on the coalface my grizzled oppo. there was a racing pigeon enthusiast who regularly ate the under performers from his loft. he claimed the 16 hour long slow cooking was the only way to make a good stew with pigeon. He said that what you did was to put them in a brown stewpot with a large pebble....When you could stick a fork in the pebble the pigeon only needed another hour.
