Happy to help!
Finding your scribed recipe books is not something you'd stumble across, lol.
- Open your Recipe Book (Press N)
- Up at the Upper right is a button marked Edit. Click it.
- The next window is actually three windows. Use the scroll bar to go all the way down... the bottom window lists all the books you have scribed.
Oh, I'm reminded that if there's anything in the filter field of your recipe book it will limit the display. When looking for your frog leg recipe, clear that box and click find.
