That&#x27;s far from an old thing - gas ovens are still in wide use, at least in the UK, and recipes will commonly mention both a temperature in degrees and the appropriate gas mark.<p>Having said that, gas ovens are a pain to use until you&#x27;ve got used to the one you&#x27;ve got. I&#x27;ve never had one where the actual temperature of the oven matched the gas mark it was set to. Typically you&#x27;ll have to benchmark it with an oven thermometer and then adjust whatever the recipe says to fit.<p>Gas hobs however, you can take from my cold dead hands. I&#x27;d rather use a camp stove than an electric hob. Nothing beats instantaneous heat adjustments.
