Bag of keel nuts (Neo)

Bag of keel nuts:

Harvested from real keel, a delicacy grown and distributed from the middle disks.

A single bag like this is worth seventeen food rations, making it wildly unaffordable for anyone except Lawmen and upper-diskers.

Tastes like almonds with a sponge-like texture, rich in protein.
