Finally got it! This really was, by far, the hardest one to get 4 stars on; I honestly think we spent more than 10 hours on this map alone.
We went through numerous different strategies, and the clean ones (i.e. where you don't just throw everything somewhat arbitrarily on the floor but rather put the ingredients one by one on the bench in the middle) simply didn't work for us. I'm blaming this on the PS4 seemingly running the game slower than on PC and Xbox, but maybe we're simply too slow 😬
Still somewhat surprised that this attempt actually worked; you can see my total confusion (me being the upper chef) out of exhaustedness a number of times. 😅
