It is difficult to bring down the ingredient as if the ingredient falls to the side in the right-hand side of the isolated squares, it is hard to bring it back to the middle as there are limited squares.
When you have your ingredient just above the candy above the exit, you have a big chance of failing in this level.
Avoid having an ingredients to fall into "stuck" zone (shown in photo). Do moves on the right-hand side. Always look for vertical striped candies. If the ingredient falls into the sides, look for possible moves to bring it back to the middle. Of course, the Free Switch will help you a lot in the level.
