makes a roasting pan full which you can package in holiday tins and/or the nut containers
Preheat oven to 250° F and get out a couple rimmed sheet pans. Melt together the bacon fat, butter, Worcestershire, and garlic salt.
Mix the cereals, pretzels, and nuts in a large crock or roasting pan then pour the sauce over everything and toss gently with two big spoons. Distribute the mix across two rimmed sheet pans and bake for 90 minutes, stirring every 15 minutes or so to bring the melted sauce up from the bottom. Store in tins, jars, or in freezer bags to save some for later.
