I love Reeses Peanut Butter cups. But man, sometimes when they get old the peanut is dry and taste really nasty. Is there some preservative that can prevent this? If there is, how come Reeses company doesn’t use it?
Peanut butter cups clearly lack the Twinkie technology. Reeses is a subsidiary of Hershey, I believe, while Twinkies are made by Hostess. (I’m not about to spend the $1.15 in the vending machine to get a sample of each to verify this.)
I think we need some industrial espionage to determine how Hostess is able to create Twinkies with a half-life of 300 years, while the peanut butter cups get dry and stale after only six years.
Some people told me that I should just eat peanut butter cups that hadn’t expired, but that’s just too easy of a solution.
Great info INO. How the heck do you know all that? Also I didn’t know there was a expiration date on a Reeses. That is a pretty easy cure if there is one.
Mmmm…reese’s…try freezing them-yummy!
Or, Bill-have you ever had chocolate peanut butter ice cream?
I’m gonna have some later! 
Guh! I hate the Reeses once the peanut butter gets all dry and flaky.
I get mine from one of those little suicide-jump type vending machines and it depresses me when my peanut butter cups make a dull, hollow ‘THUD!’ instead of a gentle ‘plop’.
