- How long does an unopened package of shortening sticks (baking sticks) last? The precise answer depends to a large extent on storage conditions -to maximize the shelf life of shortening sticks store in a cool, dry area.
Properly stored, an unopened package of shortening sticks will generally stay at best quality for about 2 years.
Are unopened shortening sticks safe to use after the "expiration" date on the package? Yes, provided they are properly stored, the package is undamaged and there are no signs of spoilage (see below) - commercially packaged shortening sticks will typically carry a " Best By," "Best if Used By," "Best Before", or "Best When Used By" date but this is not a safety date, it is the manufacturer's estimate of how long the shortening sticks will remain at peak quality.
How can you tell if shortening sticks are bad or spoiled? The best way is to smell and look at the shortening sticks: if shortening sticks develop an off odor, flavor or appearance, they should be discarded.
