The "old, old saying" is a marketing slogan from the 1930s. From the article: > It was also during the 1930s that the industry first adopted the slogan “cooking with gas”; a gas executive saw to it that the phrase worked its way into Bob Hope bits and Disney cartoons. An english.stackexchange discussion on it is at https://english.stackexchange.com/questions/25897/origin-of-the-phrase-now-were-cooking-with https://english.stackexchange.com/questions/25897/origin-of-... commenting "the actual phrase was used by Hollywood radio comedians around December 1939, and then appropriated by gas companies to promote gas cooking from around 1941 onwards ... The phrase has been attributed to Deke Houlgate, who after working in the gas industry, wrote the line for Bob Hope." We can see evidence of that in a Google Ngram view for "cooking with gas", showing the spike in the late 1930s: https://books.google.com/ngrams/graph?content=%22+cooking+with+gas+%22&year_start=1800&year_end=2019&corpus=26&smoothing=1&direct_url=t1%3B%2C%22%20cooking%20with%20gas%20%22%3B%2Cc0 https://books.google.com/ngrams/graph?content=%22+cooking+wi... . For some reason the URL doesn't work directly; you'll need to re-search. I use smoothing=1 to make the 1939 ramp-up more clear. The thing is, I also like cooking with natural gas. But the pollution and other negative effects described in the article, and the willingness of gas company PR to use astroturfing to fight any attempt to regulate, make me wary. I currently have a glass-ceramic cooktop. I want to switch to induction, which is "much faster and more controllable" in my limited experience cooking with them when visiting friends.
