Thanks for you recommendation. I was trying to think of other ways to rehydrate because I am aware of the other three existing techniques

1) Orange peel.
2) Wet paper napkin on top of jar with the cap slightly resting on the napkin. (Method I'm using now)
3) A cotton ball wrapped with tin foil with holes poked, soaked in water. Then squeezed and flattened, and thrown into the jar.
