This is one of the favorite things in my kitchen. Andy came up with this idea after watching an episode of “Good Eats” with Alton Brown. In that kitchen, the spice rack was inside the cabinet doors. That wouldn’t work in our kitchen, but we do have the back of a pantry door. We bought the metal from Home Depot and then got all the magnetic spice tins from Kitchen Collection (Bed, Bath, and Beyond has them too). We started out with 16 spice tins and continued on until we had 32. It’s awesome and I love it! It makes all the spices that we use the most so convenient and easy to find. At times, we have knocked off a canister or two by hitting them with something and we’ve had to replace a few of them, but I still wouldn’t change it.
