1. Reheat in microwave oven. Microwave heating is the fastest way to treat pistachios. Put them in clean porcelain bowls and heat them with low fire for 5-1 minutes to evaporate the water in pistachios.

2. exposure to the sun. Lay pistachios flat on a plate and expose them to the sun for 2-4 hours. You can also evaporate their water and restore crispness.

3. Return to the pan and fry. Pistachio nuts themselves are fried, so after being wet, they can be fried slowly with a small fire until there is no water and the recovery is crisp.

4. Put it by the heater. If there is no sun, you can put the pistachio in the radiator for a day and it will recover simply.
