Thank you for the reply! It's good to know that those cards from the starter pack are not mandatory.
Although, in the post, it wasn't that clearly stated, I figured it out.
But what worried me was the following question, "What if in some future Gamma packs, there would be a Recipe/Cooking card for which preparation/cooking some of these cards (ingredients) will be needed?" - For example, some bok choy soup or just steamed bok choy!?! - As if it happens, in a certain way, those cards will immediately become mandatory. - But if you say something like that wouldn't happen, then it's all good.
