Yes, I think it is.
Right now the book of recipes opens directly on the correct recipe. You have not to search it.
The recipes are quite forward and direct, so you have to translate them directly to what the one who cooked them told you. It would be interesting to add some issues on them. Different kind of measures, that you need to translate, or "small master cheff improvements" as to cook something a little longer with less temperature that the thing written in the recipe, etc.
At the same time, lets begin with simple recipes. I don't know, a sandwitch, eggs and potatoes, a bocadillo, and in further levels go to more complex ones.
There are a lot of options, but at the same time I think that a game as the one you make is more complex than the one I did. It needs much more planification and to control the difficulty is quite hard. In some way, it is some kind of RPG (it is not, it is only an expression). There are a lot of stats to calculate to balance the gameplay.
