Rehydration-Calculator for Freeze-Dried Foods

Rehydrating freeze-dried foods is an essential part of meal preparation for outdoor adventures, emergency storage, or daily cooking. However, rehydration is not always necessary—many freeze-dried foods can be enjoyed as a crispy snack or incorporated into recipes without rehydration. When you do need to rehydrate, understanding the right amount of water can make all the difference in restoring your food to its original texture and flavor.

This calculator helps you determine the precise amount of water required to rehydrate your freeze-dried food based on the weight of the portion before and after freeze-drying. Simply input the weights, choose your preferred unit of measurement, and calculate the exact amount of water needed to bring your freeze-dried ingredients back to life.
