If my sweet tooth is raging like it normally is, I’d likely pick up something fruity like Original Skittles. The way I eat them is I pour a handful out and organize them by color/flavor. I then eat them in groups of two (excuse my OCDness) from least tasty to most (Lemon<Orange<Strawberry<Lime<Grape). I sometimes (See: Often) throw the grapes back in to ensure I have a crap load left when get to the end as purple is my favorite color, and grape is my favorite candy flavor of all time :). I’ve had to cut back on my Skittle consumption recently but they will always have a place in my heart and tummy.
If we are talking strictly rectangular shaped confections, my new favorite candy bar is the Reese’s fast break. It’s like the best of a snickers combined with a Reese’s (Don’t call me Reese-E) cup. Chocolate and PB. Classic. I try to only eat a half at a time but often fail.
