Different candies, when crushed and remelted through a cotton candy machine have different levels of flavor in the final product. Specifically they seem to lose much of their aromatic properties. I suspect the original flavoring used on the cooked sugar is incredibly concentrated and a lot gets lost in the original product.

If the candies had the same intensity as they did in their drop form, I’d say they’re 100%.

If the candies ended up smelling and tasting like straight sugar, I’d say they were 0%

When I rank 50%, It generally means that it identifiably smells and tastes like the original candy and is at least reasonably enjoyable.

If you gave a bag of Werthers cotton candy to a random person who was familiar with them, they’d know what it was and likely be able to pick it out over other generic butterscotch.

I was decent, I’d have picked it over berry or cherry flavoring, but It didn’t knock my socks off, I didn’t strongly desire seconds.
