I found a few recipe creators last night - king Zace (who has been updated lenaid's harvestables) has made some of their own and they are also dabbling in creating recipes as well. link: https://kingzace.wixsite.com/kingzaceofthesims4
littlebowbob and Zace have worked together to do a slight cooking overhaul mod (where you can buy ingredients from the computer :D ) and also created some recipes as well. link: https://littlbowbub.tumblr.com/post/189416014546/grannies-cookbook-dl
also brazenlotus has some harvestables and recipes as well (not many, at the moment) but it looks like more are coming later / are going to be on BL's patreon. link: https://brazenlotus.com/category/garden-food/
