Imagine (in a non-dirty way) if Cooking Mama and Cooking Guide had a baby. What's Cooking teaches real-life recipes, and then has players simulate their preparation with touch-controlled actions. Without holding your hand, at all. I actually couldn't get past the initial steps of my first recipe, because the thing is so deep. To make a sugar paste (the first step), you have to first get a bowl out of your inventory of kitchen implements, then pour some sugar into the bowl, then mix it with a wooden spoon. To heat something up, you have to move it (via a 'stove' icon) to the stove area of the kitchen, then turn on the heat, and stir it around. The game doesn't really tell you when you're done, or even when you've failed. You just cook, like in real life. You could really learn how to cook by playing this.
