Use hot water to rehydrate for the amount of time indicated on the product package. Rehydrating can be done by both simmering in a pot and by soaking in hot water, and time for rehydration depends on both the product and the product form. Once rehydrated in hot water the amount will increase by about 3-fold.

Once rehydrated for the indicated time, place into cold water and rinse well, then thoroughly squeeze out excess moisture. Doing so will also remove excess odor.
