I consider these well worth the effort for those hours long merit/xp parties as opposed to cookies for the hmp. Personally, cookies can be very annoying for me so i prefer a 3hr+ food for hmp as a whm. I'm 96 cooking, and HQ'd this 1/3 of the time ... not sure about how fast or how well they sell ... there is literally 0 market for them on diabolos.
Gives 5hmp just like ginger cookies, without the constant annoyance of having to refresh the effect every 5 minutes.
