FOUND IT!! I didn't get the pop up for required foods but there are these recipes in Clay Oven
couldn't load the first pic for unknown reason tho :/
glad that I'm done building main goal first ovens so I could use up all my requests for this one since apparently I'm lacking its components
also, is it just me or goal threads didn't get stickied? I have to scroll down my phone to find them instead of the usual at top.
