  • Any clumping, webbing, or signs of pantry pests.

When in doubt, throw it out — the cost of a spoiled meal isn't worth the risk.

Best way to store whole wheat flour

Whole wheat flour keeps the oily germ of the grain, so it goes rancid up to three times faster than white flour. Keep it airtight and store it in the fridge or freezer — the freezer is this flour's best friend.
