Once the ingredients are ready, they get to be added to the thyme-water. In a particular order, in particular quantities, and each with a phrase in Latin from Alli's spellbook, as corrected per their earlier library adventures.

Alli stirs it three times counter clockwise, sighs morosely and sets an alarm. "And now to do that every fifteen minutes for the next six hours."
