For this Fortnite challenge, you'll need to risk a little. Pleasant Park and Craggy Cliffs are likely to be hotly contested areas, so be ready for a scrap.
To collect the four cookbooks you need, Pleasant Park is perhaps your best option. They'll always be located in the kitchens of buildings, and are typically green in colour.
The locations of some are marked on the map below.
Again, be mindful of players hot-dropping at the start of matches. Once you have collected four cookbooks, you'll benefit from a nice boost to the tune of 40,000 XP.
