When I receive the recipe "Kelryne's Recipe for Chocolate Chip Cookies of Seething Malice" from Kelryne V'Ziath, I am told that the ingredients are available in Cuisine Excelsior. But it's not on the clerk Shi'nae K'Eilsth's list. I seem to remember that I used to be able to buy them. (10+ years ago, uncertain. I'm sorry if I misremember.)
