Pistachio Nuts | Soaking and Drying (2024)

Pistachio Nuts | Soaking and Drying

Add to favorites

Did you know that pistachios are not a nut? The fruit is a drupe, containing an elongated seed, which is the edible portion. More to come on that below…

Are they Raw?

This is a great question and one that I have a difficult time nailing down. It is my guess that 95% of us who are enjoying pistachios are eating heat-treated pistachios. Fresh ones are very rare, comewith a soft shell and soft nut with a very delicate flavor. I for one have never seen a pistachio in this form.

Time to “branch out” our knowledge base…

I absolutely LOVE learning how things grow and are harvested. The pistachio is a broad, bushy, deciduous tree that grows slowly to a height and spread of 25 to 30 feet, with one or several trunks. The reddish, wrinkled fruits are born in heavy clusters somewhat like grapes.

Although known as a nut, the fruit of the pistachio is botanically a drupe, the edible portion of which is the seed. The oblong kernel is about 1 inch in length and 1/2 inch in diameter and protected by a thin, ivory-colored, bony shell. The pistachio is unique in the nut trade due to its semi-split shell which enables the processor to roast and salt the kernel without removing the shell.

My husband loves pistachios. It is common to find him with a bowl of them in his lap, unconsciously cracking and popping them into his mouth while he watches this week’s favorite TV show. I bet he doesn’t stop and examine all the colors that can be found in a pistachio… have you?

The green, yellow, and purplish-red colors found in the kernel and skins signify antioxidants and polyphenols. The yellow and green color represents the beta-carotene, lutein, zeaxanthin, and chlorophyll. Antioxidants are found in their purplish-red color as anthocyanins(cancer-fighting),polyphenols(help eliminate free radicals in the body), and catechins, which are slightly yellow or white. So next time you are crack’n and popping pistachios into your mouth, stop and admire their “healthy beauty.”

Why must we go through all this trouble? I find soaking nuts a very important step when it comes to my digestion. When nuts/seeds are soaked and/or sprouted in water, the germination process begins, in which the active and readily available amounts of enzymes, vitamins, minerals, proteins, and essential fatty acids begin to be activated.

Nuts and seeds contain phytic acid and enzyme inhibitors which make it quite hard on the stomach and digestion. This simple process can make all the difference in how you feel after consuming them and how your body assimilates them.

Ingredients:

4 cups rawpistachios, shelled
1 Tbsp Himalayan pinksalt
6 cups water

Preparation:

Soaking:

Place the pistachiosand salt in a large glass or stainless steel bowl along with 6 cups of water.
Leave them on the counter to soak for 4-8hours.
- Loosely coverwith a clean cloth, this allows the contents of the bowl to breathe.
- If you think that it will be longer than 8 hours before you can get to them, place the bowl in the fridge, making sure to change the water every so often.
After they are done soaking, drain and rinse them in a colander.

Dehydratormethod:

Spread the pistachioson the mesh sheet that comes with thedehydrator.
- Keep them in a single layer and dry them at 115 degrees (F) until they are thoroughly dry and crisp. Make sure they are completely dry. If not, they could mold, plus they won’t have that crunchy, yummy texture you expect from nuts and seeds.
- The dry time will vary due to the machine you own, the type of climate you live in, and how full your dehydrator is when drying them.
- Expect anywhere from 12 + hours.
Allow them to cool to room temperature before storing.
Store in airtight containers such as mason jars.
- Use within a month – store in the pantry.
- Use within 3-6 months – store in the fridge
- Use within 6-12 months – store in the freezer.

Oven method: (no longer raw)

Preheatthe oven to 350 degrees (F).
Spread the pistachioson an ungreased cookie sheet in a single layer.
Bake for 10-12 minutes.
- Don’t leave them unattended, due to their high oil content, they will continue to roast after you remove them from the oven.
- When toasted correctly theytaste toasted, not bitter or burnt.
- Good idea to stir them around a bit throughout the process.
Cool for about 1 hour. Make sure that they are cool before storing.
Note ~ You can also attempt to dry the pistachiosin the oven and keep them raw but this is tricky.You will need to set the oven on the lowest setting, keep the door ajar and hang a thermometer in the oven to watch the temperature.Nothing is impossible.With this method… good luck and do your best.

Do soaked nuts and seeds have to be dehydrated?

If you are unable to dry the nuts or seeds, it is best to only soak an amount that you can be sure will used within two or three days. As with any live food, mold tends to set in within days if you’re not careful. They will need to be stored in water, sealed tight, and placed in the fridge. It is important to rinse them twice a day with fresh water.

Do we shell them before soaking ? I’ve read higher heat than 150 degrees reduces the healthy properties in the nuts or seeds. So I’m trying the oven. My old oven goes as low as 115 degrees. I have not left the door open before – do I need to do this? What benefit does it offer? Thank you so much!

  Yes Celia… all nuts and seeds need to be shelled before soaking. That’s awesome that your oven goes down to 115 degrees… not many do. You don’t need to crack the door, that is just for ovens that go down that low, it helps to reduce the oven temp that way. Enjoy and have a blessed evening, amie sue

    Hi Amie-Sue, You are so lovely to reply! I did shell the raw pistachios – soaked them in salt brine for 8 hours. Instead of drying, I read about an alternate choice of keeping them in water (changed 2 x per day – in fridge) good for 2 to 3 days. (I soaked a small amount for about 3 – 4 servings as a trial) They are WONDERFUL, full of pistachio taste!, so rich and amazing.
    Thank you so much for replying, I’ll try drying the next batch. Yes, my oven is literally from 1965! My grandparents original home and oven! It goes nearly as low as 100 degrees and is easily kept below 150 :-) Never knew I’d be glad about that until I recently discovered “Soaking” :-) I even soak flour (using so little & rarely, but soaked! :-) and oats, buckwheat … everything grain, seeds or nuts. It makes perfect sense!!
    The Old World knew best about this! Our modern overly processed, fast, mass producing food industry lost that wisdom for the most part. Makes one wonder if gluten would be such an issue if we hadn’t.
    Best wishes, Celia.

      That is so wonderful Celia. You have a true relic on your hands and I love the memories attached to it… ohhhh the history! You are blessed. These days everything is made so cheaply and without character. Thanks so much for sharing a bit of your history with me. I really enjoyed reading about it.
      And who knew that pistachios could be so rich in flavor huh?! Many kitchen blessings and have a wonderful weekend. amie sue

Thank you so much for this valuable information!
I intend to use mine for chocolate making purposes as well as consuming them myself 🍴
Curious, though ..must I add salt to the water? I ask bc I plan to sprinkle it on the finished chocolates.
Thanks, again, in advance 😁

  Hello Catherine,
  You are so welcome. It’s my pride and joy.
  The salt helps to draw out the phytic acid, etc. It really doesn’t affect the end taste of the nuts/seeds if you use the ratio indicated. Good luck with your chocolate making! amie sue

What if I soak it in Honey for multiple days, is it still healthy to eat pistachio?

  Good morning Arsh,
  Honey-coated pistachios sound yummy. Are you asking me if it would have the same effect as soaking them in water? If so, not to my knowledge, but it wouldn’t hurt anything. Blessings, amie sue

    Hi. Once I have soaked it with the shell for around 3-4 hrs in normal water, can I directly eat the nut by removing the shell?

      Good day Rhss,
      I don’t soak my pistachios or nuts while in their shell; I am not familiar with this practice, so I can’t advise you. When I soak nuts or seeds they are shelled first. amie sue

        So, assuming i soak them unshelled, then is it ok to eat immediately after soaking for 3-4 hrs?

      I have never soaked nuts in honey. It would taste good, I am sure of that. :)

I bought pistachios – Dry roasted unsalted. I shelled them. I want to chop them to use to top shortbread cookies. There are a lot of ‘skins’ on the nuts – not too attractive and too much work to scrape them off. Is there an easy way to remove the ‘skins’? I’ve never considered the skins a problem before when shelling and eating – just not sure if I need to remove them – pretty sure they will be more attractive without them.

  Hello Pat,
  You can go about this a couple of ways. You can place them in a kitchen towel, fold it over, so the pistachios are sandwiched between them, and vigorously rub the fabric over them to loosen the skins. Much like you do with hazelnuts. Another method is to give them a flash soak in boiling water. But you still have to pinch the skins off like you do when removing the skins from almonds. No matter what, it’s going to take an extra step or two and a little bit more of your time. I hope this helps. blessings and Merry Christmas. amei sue

Hi Amie-Sue,
Thank you for this post. :-)
I just bought some roasted unsalted pistachios. Is it too late to soak them now since they’ve already been roasted, or would soaking them still have the same effect of removing the phytic acid?

  Good day Aziza,
  I wouldn’t worry about soaking the pistachios since they have been roasted. The roasting process reduces the phytic acid. blessings, amie sue

I’m confused about what is a shelled Pistachio and what’s not.
In the picture at the beginning of this article there is a bowel of pistachios are they shelled or unshelled?

I buy the Wonderful brand of Pistachios that are already roasted. Will soaking make any difference after they’ve already been roasted?

  Hello Mark,
  From what I have read over time, it doesn’t really benefit to soak roasted nuts or seeds. The roasting process does reduce some of the phytic acid, but not the same as soaking raw ones.
  Have a wonderful evening, amie sue

I want to use pistachios in a Puerh tea. Should I use raw and pulverize them a little in my mortar and pestle? Or use them whole, after shelling of course.

Hello Hope all is well.
We just received a fresh pistachio from a friend, that he got them from their own trees in Turkey.
My questions is: How to cure fresh Pistachio?? Is this the same as soaking with salted water?

  Good day Airene,
  I am sorry for not getting back to you sooner! I am sure you have dealt with the pistachios by now. Frankly, I don’t know the answer to your question. I would have to Google it, just as you. I’ve never been in the presence of fresh pistachios! I am sure that there is a drying process! Let me know what you came up. Inquiring minds want to know! amie sue
