Eve never left the HW compound until and her first time entering the spice shop on the show was in ; she had turned into Renard using the Verfluchte Zwillingsschwester spell the previous episode, before Rosalee had ever met Eve in person. We have to remember that HW is a secret part of the government that had its own secret funding, so they didn't have a problem getting supplies that they needed, especially since the plan of turning Eve into a weapon for them had been in the works for quite some time. Eve's cell was stocked with its own supplies for her, including the hat and, yes, the Zaubertrank Recipe Book as well.

There's visual evidence that confirms Eve's book was different from Adalind's as well--as you can see, the Verfluchte Zwillingsschwester recipe pages in each book are clearly unique:

I hope this clears up some confusion. Going back to ep603, it looks like Eve was using the book she'd used at HW since the page with the illustrations is on the left side.
