The best way to store flour is in an airtight container, so that nothing unwanted gets into your flour and so that the flour stays fresh, longer. There are all kinds of airtight containers out there that you can choose from, but it makes things a lot easier when you opt for a container designed for flour storage because you get a few extra features that will make the container easier to use.
The Progressive International Flour Keeper DKS100, for instance, is a great example. This rectangular keeper holds up to 5 lbs – a standard, grocery store bag – of flour at a time. The lid has a locking clasp that snaps down tight to create an airtight seal, yet is still easy to open with one hand. The opening is very wide, allowing even large measuring cups to fit inside with ease. The best feature, however, is that this container comes with a built in flour leveler just inside the lid. The leveler allows you do do a “scoop and sweep” measure with your measuring spoons or cups without dirtying any additional utensils. The only time that you wouldn’t be able to easily us it is when the container is newly-filled and flour comes all the way up to the rim, but otherwise it is always there when you need it.
