How to Soak Pistachios

Updated April 12, 2017

Nuts contain nutrients and vitamins that are beneficial to the human body. These nuts, however, often contain bacteria on their surface which must be removed before eating. Unlike most other shelled foods, which can be simply washed, nuts such as pistachios need to be soaked for long periods of time. The soaking is then followed by a dehydration stage before being ready to be eaten.

Mix 1 tsp of sea salt in one 236ml cup of filtered water. Stir until salt is fully dissolved.

Pour the pistachios and water/salt mixture into the bowl. Mix more water/salt mixture as needed until the pistachios are fully submerged in water. Let the pistachios sit for 12 hours.

Strain the pistachios, disposing of the water/salt mixture down the sink. Rinse the pistachios with fresh filtered water, and strain. Fill the bowl of pistachios with water one more time until they are submerged. Throw away any nuts which float to the top of the water. Strain.

Preheat your oven to 37.8 degrees Celsius. Place the nuts on a baking tray, and bake in oven to dehydrate them for 18 hours. Check a few of the nuts to see if they are completely dry. Let bake for a few more hours if necessary to ensure complete dryness.
