@KATENESS My chef cooked the meals out of order, and the badge triggered precisely when it was supposed to. I would point out, though, that sometimes a sim with the natural cook trait will autonomously "kick it up a notch," turning an outstanding meal into a perfect one, and I think that the resulting meal wouldn't count towards the total. So you might want to check the quality just as your chef is plating each meal. And your sim might need to make group meals, but I don't know for sure because that's all my sim ever made.
