For example, the ginger on the lowest shelf near the middle has 47¢ stamped on the bottom and the container doesn't have a bar code. The expiration date on the baking soda on the top shelf is 01 28 91; this baking soda still works for odor control and rising (one recipe we use) has baking powder and baking soda. The ginger has a faint smell but of course it hasn't been used since we use fresh ginger. It is possible that one or more of these items predates moving here.
I'm actually going to throw out some of this stuff since we want to relocate some other stuff to the top shelf.
