For anyone that didn't understand that, the intermediate cookbook is found on the Lakeview map in the house directly south of the fast travel post board. If you already have the location discovered for fast travel, it is very easy to get to: fast travel Lakeview, house directly south of the starting location. House has two doors in it, the right one opens now.
What it unlocks is intermediate crafting options for the garden and water buckets. You can craft and install them, Leslie says a few words for the garden. That's it. Much like the air conditioners, they are available to craft and install now, and likely gate progress with the girls in future updates.
Update impression, feels more like a finished 3.0 than a 4.0, would've made more sense to designate it 3.5 but I understand why. Animations still great, looking forward to inevitable Leslie/Ashley three way.
