For about 1lb of nuts, mix around 60 grams of salt with 650 ml of water. You can experiment with the ratio of salt to water until you get a taste you’re happy with. A more concentrated solution will yield saltier nuts.
Add nuts into a deep bowl.
Fill the bowl with brine until the nuts are completely covered.
Now, cover the bowl adequately and place it somewhere cool and dry.
Soak the nuts overnight for better results. If you want to reduce soaking time, boil the brine. This way you only need to soak the nuts for one to two hours.
After soaking, drain all the brine.
The nuts will be a little soggy from the soaking, so now you need to dry them out again.
You can either put them in a dehydrator or in the oven. If you're using the oven, dry them on a low heat for longer to make sure they don’t burn.
Different nuts will take different times to dehydrate completely. Check the nuts regularly and take them out when they reach your desired taste and texture.
Leave the nuts to cool before you eat/store them. As you heat the nuts their natural oils come to the surface, making them seem soggy. They will crisp up as they cool and the natural oils are reabsorbed.
