How to Rehydrate Dried Blueberries in a Microwave

Rehydrating blueberries in the microwave is fast but comes with a significant risk of overheating. Overheating destroys the nutrients in dehydrated food and often leads to uneven rehydration.

Depending on the number of blueberries you’re rehydrating and the strength of your microwave, adjust the microwave time and reduce the power to 50% or less to reduce the risk of overheating.

Here’s how to rehydrate dehydrated blueberries in the microwave:

  1. Place the dried fruit in a heat-safe plastic resealable bag.
  2. Add plain water or a mixture of brandy, rum, and water while removing excess air from the bag.
  3. Seal the bag. This will help increase the surface area between the water and the dried fruit to ensure none of the berries will be left without moisture.
  4. Heat the dried fruit in the microwave for 1½ minutes. Remove the fruit from the microwave and let the bag sit undisturbed for 10-15 minutes.
  5. Drain the excess liquid from the blueberries using a colander or sieve, and use the blueberries as desired.
