If you have a stainless steel refrigerator, you can incorporate a built-in spice rack by using magnetic spice jars. These spice jars have magnetic bottoms that stick to the refrigerator door, creating a space-saving and convenient storage solution for your spices. Magnetic spice jars come in various sizes and designs, allowing you to customize your spice collection. This idea is not only functional but also adds a modern and sleek touch to your kitchen.
