Don't let canned goods go to waste. Use a rotating shelf to inspire recipes and keep your cans from hiding at the back of the pantry. WikiHow details how to build a rotating canned food shelf that works in whatever cabinet space you've got. How does it work? The shelves are designed so that freshly purchased canned goods are loaded into slots. The cans roll down into a chute and push the oldest cans forward. This ensures that older cans are presented before the younger ones, saving them from being lost in the depths of a kitchen cabinet or pantry shelf. The tutorial covers building your own shelving unit from scratch, but the basic principle can be easily modified to work with your existing pantry shelves.
