my guess would be:
there should be a second batch of cany crafting, once the ult candy limit is done, another recipe would show up, making the first recipe unusable. So I guess the point of my theory would be that you should craft everything as possible before the other one comes.
Nope, the Licorico, Peanut Crunch, Bubble Bubble, and Malt Munch are completely useless. They're just like the normal Halloween candies you can get in the pack, and they act as fillers so there's more stuff to look for besides just the Ultimate Candy crafting components. But nope, they have no use other than decoration in a glass block. Or eating. You can eat them too.
