I will share my tips of storage for small spaces. But there are some ingredients that you just cant really store in a small space. Like the 25 pounds of all purpose flour I use a 5 gallon bucket with a lid that I use my hands to pound it down around the top to make sure it is sealed all the way around. I like to get the square 1 gallon plastic screw top containers from Walmart Mainstay brand for smaller amounts of the flours that I use for baking. I am still in the long process and never ending process of searching for storage ideas for my small kitchen. But that is actually a never ending issue with wanting and doing more and more made from scratch type of cooking.
