Darling smashes the graham crackers inside a sandwich bag.
Warning: Marshmallows toast quickly. If you leave them in too long, they will burn, just like when you roast them over the fire. Should this happen, and smoke begins filling your kitchen, PANIC!!! Run around like a maniac and scream "Where's the fire extinguisher!" (Note to self: Keep fire extinguisher in a handy place for baking and cooking...)
Now, if I can do it, you can do it! Okay, okay...I didn't do it. But I watched, and it seemed pretty darned simple. So go make s'mores with your kids or grandkids this weekend. And if you haven't got children, well, borrow the neighbors kids. Better yet, don't, and you'll have more s'mores for yourself!
