You’ve got plenty of moves to bring down the Ingredients, so first focus on destroying the Evil Spawners at the center of the playing field. Although they won’t spread the Icing too far because of the Conveyor Belt, it’s still nice to have them out of the way because it will become easier to make special candies with them gone.
While you’re destroying the Evil Spawners also clear as many Licorice Swirls and Sugar Keys as you can you. After all, fewer blockers on the playing field means more space without them which makes making special candies easier.
You can only collect Ingredients in the middle three columns so you’ll first have to move the Ingredients onto the Conveyor Belt and wait until they move into the middle three columns before you move them off the Conveyor Belt. You can also force the second Ingredient to spawn in one of the middle three columns by matching candies in those columns right after you’ve collected the first Ingredient.
As for the Color Bomb candies that spawn from the Sugar Chests, just use them to clear Sugar Keys or clear candies below the Ingredients.
