It turns out that biscuits are like fresh flowers - they're best enjoyed immediately, but with proper care, they can last for several days. If you store them in an airtight container at room temperature, you can expect your biscuits to stay fresh for around 2-3 days. But, if you want to get all scientific about it, the starches in biscuits start to break down as soon as they're baked, which affects their texture and flavor.
Now, here's a quirky fact: did you know that biscuit freshness is also affected by the type of flour used? It's true! Biscuits made with all-purpose flour tend to last longer than those made with bread flour, which has a higher protein content. Who knew that something as simple as flour could make such a big difference?
