from Scatterbrained by Ransom Riggs, Will Hickman, and Hank Green
"worth bearing in mind if you're stocking a fallout shelter: NECCO's classic Valentine's Day candy hearts stay edible for about five years. (Which, incidentally, makes them a far better choice than twinkies. Despite what you may have heard, twinkies get rotten and moldy within a couple of months.) If you're like us, you've always thought that all NECCO hearts taste like the exact same variety of sugared chalk, but it turns out that each color (supposedly) has a different flavor."
chalky and no real distinct flavor...i still love them! enjoy your day!!
