Firearm manuals won at auction and a recipe?

The only thing that confuses me is the removal of berries after it works for 10 days.

Is it Berries or Cherries? I'm guessing that by that time it's broken down and the juice out of the fruit? I would think you had to mash the Berries or Cherries first though Hmmmm is that what it says in prentices (Mash cherries before putting in ????) ?
