"Flour made from grinding any sort of grain. Used in baking and cooking, it is the stable of many societies, including here on the rim. Very long lasting with a 2 year shelflife (sic)."

Flour is a food item added by the Core of RimCuisine 2. It can be made with varying degrees of difficulty at the Cooking Spot, Quernstone or Roller Mill from, as the description says, any type of grain.

It can be easily stored in kitchens for quick access with its incredible shelf life of 2 years to meet the vegetarian nutrition of a meal or used to create Hardtack, an even longer lasting food item that slightly reduces the mood penalty to -4.
