Ooh! This is gonna be fun! XD 

Since this is her first time cooking, I think she's going to use Wisdom, since she's learning about the new ingredients while she's cooking and making sure that she doesn't accidentally poison anyone. 

As she's cooking a stew (since it's a basic dish), she'll take a whiff of each herb or spice she's putting into the dish so she would get some sense of what the dish will taste like, and what combination of vegetables go well with each other. The herbs will be minced, while one long herb will be left as a sort of decoration in the pot.
