I liked playing this game. I can see it growing with for example more recipes and more ingredients. I had to play around in the game a bit first, but then it got clear to me what to do.
Maybe it is intentional, but I have to buy ingredients when I do not know what recipes will show up the next round. This makes the choice for what ingredients to bring not interesting, since it is unknown what you need. So the optimal strategy is always to bring something from everything? Maybe more green onions (if that is the correct word), because some recipes require this twice. But the optimal choice is always the same.
