The Cafe World spice rack works much like the FarmVille horse stable or the Mafia Wars chop shop, you must ask friends for parts to build your rack. To complete the rack, you'll need five of the following: shelves, small jars, medium jars, large jars and lids.
These items can only be acquired as gifts from friends, so be sure to sent parts to friends, and ask for them to send some back to you. You know -- scratch their spice rack, and they'll scratch yours back.
Once the rack is complete, you'll earn five Cafe Cash, which is a 'W00t'-worthy bonus. Here's the bad news -- the racks don't do anything other than hang on the wall and look pretty.
Before you decide to march on Zynga with meat cleavers in hand, it seems like there will be added spice rack functionality down the line. If you look closely in the spice rack's pop-up window below -- there's a note that says exotic spices 'coming soon.' Look like we'll have to wait and see just how 'exotic' these new ingredients will be, and what that means for our cafe menu.
