Changing what you have baked

[mytsa]

As in my test (pls see #4), I 've got partial refund for the 1st recipe.

I don't think so. If you start a new recipe, you will be charged the full cost of that recipe and you will not be refunded the coins you spent starting the first recipe. There are no refunds in this game. Just like if you store the appliance with the food cooking on it you lose the food and the money you spent.
