Add a new rule to the ruleset, entitled Challenges:

All Cooks have two variables that are tracked in the GNDT, called Skill and Honour. Both variables must be numbers of zero or higher, and default to zero.

A Cook may challenge another Cook to a Cook-Off, by making a story post naming the challenged Cook and setting out the parameters of the Cook-Off as per this rule. A Cook may only issue a challenge to a Cook-Off if neither they nor the Cook being Challenged have participated in a Cook-Off in the preceding 48 hours, and if there is no more than one other Cook-Off under way at the time the challenge is made.

A Cook-Off challenge must name a single Cook and challenge them to create a recipe that has specified Valued Properties. The Cook so named then has 48 hours to post a recipe that has those Valued Properties. If the challenged Cook does not respond to the Cook-Off then any Cook may lower their Honour by 1.

Once the challenged Cook has responded to the Cook-Off, the Restaurant Manager should indicate whether or not the recipe meets the Valued Properties set out by use of the voting icons. If the Restaurant Manager indicates that the recipe meats the criteria then the challenged Cook may increase their Honour and Skill by 1 each, and the challenging Cook may increase their Honour by 1. If the Restaurant Manager indicates that the recipe did not meet the criteria then the Cook who made the initial challenge may post a recipe of their own, which the Restaurant Manager should assess in the same manner. If this second recipe is deemed to meet the criteria then the challenging Cook may increase their Skill by 1; if it does not then they must lower their Honour and Skill by 1 each.
