Keeping Your Flour Pantry
Flour is more than just a dry powder; it is a living ingredient that reacts to its environment. If you want consistent results in your baking, you must treat your storage like a critical part of your process.
Consistency starts before the oven is on.
If you buy flour in bulk, decanting it properly is the difference between a usable pantry and a magnet for pests.

- 5-10 lbAll-purpose, bread, or whole wheat flour
The Airtight Barrier
Flour absorbs odors and humidity from the air; keep it in a sealed container to ensure it stays neutral in flavor and doesn't clump from dampness.
The method.
Inspect the flour
Before putting it in a canister, check the bag for any signs of small webbing or movement. If you see signs of life, discard the flour immediately.
Transfer to containers
Pour the flour into dry, sanitized canisters. Leave a small amount of headspace at the top so you can easily reach in with a scoop.
Label and date
Stick a piece of tape on the bottom or back of the canister. Write the type of flour and the date you opened it. This prevents confusing bread flour for cake flour later.
Place in a dark, cool spot
Store canisters in a dark cupboard away from the stove or dishwasher. Heat and light degrade the natural oils in the grain, especially in whole wheat varieties.
Other turns to take.
Cold Storage
Whole grain flours contain oils that can turn rancid quickly. Keep these in the freezer in a heavy-duty freezer bag or sealed container to extend their life significantly.
When it doesn't go to plan.
Never top off a canister with a new bag of flour. Finish the old batch entirely, wash and dry the canister, then start with the fresh bag to prevent old flour from settling at the bottom.
If you notice your flour smells slightly musty or has changed color, discard it; it has likely gone rancid.
Store flour away from strong-smelling spices, as the starch will pull those aromas into your future loaves.
The ones that keep coming up.
Can I store flour in the bag it came in?
Only if you put the entire paper bag inside a larger, sealable plastic bin. Paper bags allow moisture and pests to pass through easily.
How do I know if my flour is still good?
If it doesn't have an off-smell and there are no signs of pests, it is fine to use. Test for moisture by feeling if it has formed hard, solid clumps.
