Hi,
First things first, if you read the changleog carefully for 0.3.4, you'd know that there's only one recipe at the moment, dev is currently in the middle of implementing another one - whenever a recipe is added it will be specified in the changleog.
AS for the cooking minigame, I'd advise you to check out the vids that dev posted here, or even better, on our Discord server where he shows how to cook food or you can still try to figure out how to do it by yourself.
Cheers
