Well we can’t change things on a different layout than the one we are on. You could make the ingredients global so they transcend layouts. Aka, they won’t get destroyed when you change layouts. But you’d need to clean up the ones you didn’t want to transfer.
You could just store a list of the ingredients in an array or global variable, then when you move to the other layout you’d look at that the list and create objects from that.
Simpler still to me could be to make the game all it one layout. Just jump the scroll position between the two areas.
Anyways, just some ideas.
