Why do brandy snaps require airtight storage?

Here's why:

* Ingredients: Brandy snaps are made with ingredients that are very hygroscopic, meaning they readily absorb moisture from the air. These ingredients include:

* Sugar: Sugar is a very good absorbent of moisture.

* Flour: Flour, particularly when finely ground, can absorb moisture.

* Butter: Butter contains water, which can evaporate and be reabsorbed.

* Thin and Crispy Texture: Brandy snaps are known for their delicate, thin, and crispy texture. If exposed to air, they will quickly become soft and soggy.

* Structure: The crispness of brandy snaps is achieved through a process called caramelization, where sugar molecules change their structure when heated. This structure is fragile and easily affected by humidity.

Therefore, storing brandy snaps in an airtight container helps to:

* Prevent Moisture Absorption: An airtight container acts as a barrier, preventing moisture from the air from reaching the snaps.

* Maintain Crispness: By keeping the snaps in a dry environment, their texture and crispness are preserved for a longer time.

Tip: If you're storing brandy snaps for an extended period, you can consider placing a small packet of silica gel (a desiccant) in the container to absorb any excess moisture.
