I had this for the first time around Christmas and immediately started begging my mom's best friend for the recipe. I was surprised to hear the ingredients like the popping oil, but it magically soaks in to the crackers and everything stays crunchy...even when it's stored in the fridge. She suggested instead of the cookie sheet just using big ziplock bags. I substituted Cheez-its for Chex and added extra dill because I love it. Keep in mind this recipe will make an obscene amount so you really might want to cut the ingredient amounts in half.
