What is a Reese's cup? It is sweet and it is salty. What is barbecue? It is sweet and it is savory and it is salty. What is bacon? It is salty. What is a brioche bun? It is sweet. Great food is all about tweaking the equation to get that perfectly balanced bite. This might seem like a lot to balance, but those maniacs might be able to pull it off. Especially if you keep the Reese's in the freezer before putting them on the sandwich, and you throw the pork on the sandwich while it's still super hot. The Reese's will start to melt just enough that it'll add a little crunch to the bite but then melt in your mouth.
