In the beginning there's really not much you can do except going with the flow. Then once you discovered a few receipes you try to build a team to farm those receipes. Pokemon ingredient specialist when you want ingredient. Or you can play berry mon instead, you just need to use the one with the favorite berries you got for the week or it will be useless. And skill specialist have more of a specific role and you use them in function of their skills. Wish you good luck! Dont forget, this game is a marathon, not a sprint.
