I have to admit, I really didn't understand what the folks at Reese's had in mind when they first released these Reese Mini peanut butter cups. I thought this was some kind of scam at first. Don't they already have those smaller, individually wrapped, Reese Peanut Butter Cups? I was wondering if this was just some kind of re-branding/marketing ploy to sell those again. Upon inspection of the contents of this package, I finally get it. The individually wrapped Reese cups are “small”, these are “mini”, or smaller than small.
The great success of this treat is the understanding of proportion and ratio. If the chocolate was too thick it would not have worked, if there was too much or too little peanut butter, it would not have worked. The folks at Reese understand that changing the size of a treat involves a great deal of thought towards ratio of ingredients. In some cases, when a treat changes sizes, the proportion of ingredients has to change in order for it to work well at its new size. It could be because of the texture of one of the ingredients works at one size and not the other, it could be because one ingredient has a much more powerful flavour. I'm not sure of the candy math, but when it comes to peanut butter cups, but Reese's got it right on.
There was one strange thing about these little cups. They seemed to be a little chewier than I remember regular Reese's Peanut Butter Cups being. It might have something to do with the oil from the peanut butter leaching into the chocolate changing its consistency. I'm not sure what it was, but it was a little strange.
