  • Store in cool, dry area.
  • Time shown is for best quality only — in most cases, baking powder will not spoil, but it will lose its potency over time and not perform as intended.
  • To test whether baking powder is still potent enough to be effective: add one teaspoon of baking powder to one-third cup of hot water — if mixture bubbles, the baking powder is still potent enough to use.
  • “Best By,” “Best if Used By,” and “Use By” dates on commercially packaged foods sold in the United States represent the manufacturer's estimate of how long the product will remain at peak quality — in most cases, the baking powder will still be safe to consume after that date, although it will lose potency over time.
