Just so you know, this page is basically discontinued after the big adult game ban that happened a few weeks ago. My main places of activity are my Subscribestar page, and my Discord.
There are no new meals to discover, but the whole sandbox mechanics will get some love on the very next update (0.5.5) and the amount of recipes to get may possibly increase. The greyed out option is linked to Riley's quest Juggernaughty. You can disregard it if you're not actively working on this quest.
