Alexander's plan for his food recipes was mostly as Lady Parthia suspected.
Money, land, and titles were all good… but for some, a cooking recipe was much more valuable.
It was also something more personal and less transactional, thus creating stronger bonds.
Alexander hence planned to give some of the easier and simpler ones as gifts to potential allies and as rewards for success and loyalty, while keeping a few more unique ones for yourself.
And when he was coming up with this plan, Alexander was glad that he was not short on recipes- although he had re-created a lot of dishes, there were also lots of them left in his hat.
