You have to bring 2 ingredients down each side of this. So what you need to do is shoot through the pieces off to the side to drop the ingredients. So 1 shot through the top will drop each ingredient to the first box. Another shot through the bottom row will get the ingredient to the second row. Lastly, you will have to shoot a vertical striped candy through the spinner below to drop the ingredient. Note that there are only 3 colors here to work with to make it possible.

Horizontally striped candy matches will work to drop the ingredients (you need 2 matches), but they have to be in the exact rows as the isolated candies on the sides; striped/wrapped combos require less precision. Vertically striped candy matches really work the best to propel the ingredients through the exits.
