You need to either use horizontal striped candies to shoot through the blocks in the left column or you can opt to try to create a color bomb and then mix it with a striped candy to push a lot of the candy through and at least one ingredient. If you have more than one ingredient, you should be able to get away with the color bomb and striped candy to slip through. Remember to match candies over in the left whenever possible to move ingredients down. The hardest blocks to remove are the top white blocks, so any chance you get fire away at them. A wrapped/striped mix is great to help remove multiple lines of white blocks.

A couple of striped/wrapped combos should break and clear the blocks on the left and simple matching will get the ingredients out. If you get stuck without any possible matches in that area, try another striped/wrapped combo or horizontally striped candy matches to move things along.
