All the recipes are based on real life ones and use legit ingredients and require similar steps. The game won't teach you how to actually do some of the manual work because that's something you'd have to practice IRL and also the preparation times have beed reduced so that the game is playable and fun. I guess nobody would want to wait 30 minutes for the fish to bake when playing a game. I think that the game can give you a general idea about cooking and possibly giving you a little push towards trying to cook something in your own kitchen :)
