Just a thread for strategies for the ingredient levels in general. Feel free to post and tips about how to go about beating the ingredient levels.
One tip I found helpful is that not all the ingredients needed to pass the level appear at once, and you need to push the board down a bit before the others begin to appear.
If the board is not a perfect square, look around to see if there is a shorter route down for the ingredient to go. Although it may be difficult to change columns with an ingredient, keep your eyes open!
