Part of the problem with making Halloween food is that sometimes:
1.) It IS disgusting but doesn't taste that great, OR...
2.) It's not that gross, but IS tasty.
instructables came up with a recipe for eyeballs that is truly awesome.
I mean, look at those things! And they're made with fruit? Amazing.
I Make Projects uses Penn & Teller's recipe for Chilled, Bloody Heart that results in an amazing chilled, bloody heart.
Here's some more shots of the heart being presented to its delighted diners.
