I have a house full of picky kids, so I end up with lots of open boxes of cereal. This works with pretty much any cereal you'd want to eat. I've used Kix, Apple Jacks, Rice Krispies, Cheerios, Cocoa Puffs, even Life! I like the stick or mini pretzels the best. I'd bet the big sourdough ones, crushed a bit of course, would be really good too. Please please please be very careful with the boiling syrup. Keep an ice bath nearby in case you spill on yourself. Any seasoned candy maker knows how horrible candy burns are.
