The entity with the greatest influence on what Americans cook is not Costco or Trader Joe’s. It’s not the Food Network or The New York Times. It’s Google. Every month about a billion of its searches are for recipes. The dishes that its search engine turns up, particularly those on the first page of results, have a huge impact on what Americans cook. Which is why, with a recent change in its recipe search, Google has, in effect, taken sides in the food war. Unfortunately, it's taken the wrong one.
