FAQ:
Q: How can I speed up the drying process?
A: A dehydrator would be ideal, an oven might work as a dehydrator if it has a low temperature setting and good air flow. You can also just leave it to dry in a warm place. Beware that the more you try to speed up the drying process with direct heat, the higher the risk that the bowl will warp.
