I think this is a great idea, and with some more content and polish could end up being a great game.
That said there's a couple of glitches I'd like to report. Firstly, the quests and recipes menu on the side just stopped working at some point, I could still scroll up and down but I couldn't swap between menus or dismiss it.
Second, you can process the same ingredient multiple times by putting it in a different tool while it's being processed. For instance, I put the chef and tomato on a cutting board, before it's finished move the tomato onto the bowl, when the chef finishes you have chopped tomatoes and the original tomato stays in the bowl
