The crunch of a dry biscuit depends less on the recipe than on humidity and storage. Here’s how to keep the perfect texture… and how to rescue a biscuit that has gone soft.
1) The golden rule: airtight container
As soon as biscuits are completely cool, store them in an airtight container. A biscuit sealed while still warm = condensation = softening.
2) What makes them soften fastest
- Humid rooms, an active kitchen, steam.
- Biscuits stored together with soft products (madeleines, cakes).
- A poorly sealed or oversized container (too much air).
3) Restoring the crunch
Place in a low oven for a few minutes, then allow to cool completely in open air before closing the container again.
FAQ
Most often because they were sealed while still warm, the container isn’t fully airtight, or the surrounding environment is humid.
Yes, as long as they are all dry biscuits. Avoid mixing with soft products that release moisture.
No. The fridge adds humidity and often makes dry biscuits soft.
