It was, we suppose, inevitable. Nintendo's Cooking Guide released in Japan two years ago (as Cooking Navi), where it shifted a decent number of units. It recently emerged in Europe, and did pretty well there, too (it'll be coming to the U.S. this November). And what happens each time Nintendo releases a successful non-game? Answer: as sure as night follows day, (usually inferior) third-party alternatives appear.
That's what has happened here, with Atari following Nintendo into the cooking-with-your-DS arena. What's Cooking? with Jamie Oliver will feature 100 recipes (Cooking Guide has 245), space for 100 of your own, a shopping list mode, and competitive cooking games. It's very similar to Nintendo's game then (though apparently you can share recipes via WiFi), except you get to look at Jamie Oliver and his smug, squishy, Mockney face a whole lot more.
If, like this blogger, you regard Oliver as an affront to all that is decent about humankind, it might not be your thing. But it might be okay as a game.
