Expiration & Storage Tips
When does biscuit mix expire?
Biscuit mix generally lasts for up to one to two years past the printed date on an unopened package, depending on the best-by or use-by date. Once you've opened the package, it's usually good for another six months if stored properly. If you pour the mix into an airtight container and freeze it, it may last indefinitely. However, it's worth noting that while the mix won't become unsafe to eat over time (assuming it's been correctly stored), it may lose some of its leavening power after its best-by date, which could affect the rise and texture of your biscuits.
How do you tell if biscuit mix is bad?
Check your biscuit mix for signs of spoilage before using it. These signs can include an off smell, a change in color, or the presence of mold. Any unusual or sour smell is a clear sign that the mix has gone bad. Be sure to also check if any bugs have managed to get into the package, as they're often drawn to dry mixes like this. If your biscuit mix has clumps, that could be a sign of moisture getting inside the bag, which could lead to spoilage so it's better to toss it.
Tips for storing biscuit mix to extend shelf life
• Always seal your biscuit mix properly after each use to keep out air, moisture, and bugs.
• It's always a good idea to store it in a cool, dry place away from heat and direct sunlight. The pantry or a kitchen cupboard would be just right for this.
• Consider transferring the mix to an airtight container for longer shelf life once it's been opened. Tupperware, mason jars, or even ziplock bags work well for this.
• For an even longer shelf life, you can freeze biscuit mix in a freezer-safe container. Just remember to defrost it fully at room temperature before using it.
