Thanks for the feedback!
The ingredients are selected from the pantry at random, to add "risk". The shop, and the effects of the ingredients are intended to give you some more control over what ends up being selected.
We let players see the ingredients in the pantry, so that you can decide whether it's worth the risk to draw another one from the pantry (sort of like a deck builder game showing you the cards in your deck). But, it sounds like we could have conveyed that better.
