Start by rinsing cashews thoroughly, then soak them in water.
For optimal results, soak cashews in cold water overnight (7-8 hours) or expedite the process with hot water for 3 hours.
While this soaking step is optional when using a high-speed blender, I recommend taking the time to soak the cashews for an even creamier texture, whenever possible.
If you prefer to keep the soaking water and use it when blending, make sure you use boiled but cooled down to room temperature water when soaking for 7-8 hours or boiled water for 3 hours. Alternatively, you can use filtered water.
If you want to discard the soaking water later on, then just use tap water to soak cashews.
When the soaking time is up, it's time to blend. Simply add the soaked cashews, water (in total around 700 ml), a pinch of salt, and dried dates (optional), then blend.
I have Blendtec Designer 625. With this model, I recommend using the 'Ice Cream' cycle followed by the 'Whole Juice' cycle. These two cycles, which take around 2 minutes, ensure a smooth texture for any plant milk. After blending, it's crucial to taste and assess the texture. If you find it too thick, simply add a bit more water and blend for 10 - 20 seconds to achieve your desired consistency.
If you're using a regular blender, blend a bit longer and stir any solid bits at the bottom between each blend. Before pouring the cashew milk into your glass bottle, consider using a sieve, cheesecloth or nut milk bag to strain out any remaining solids for a smoother texture.
Now, relish the fruits of your labour – your homemade pure cashew milk: no additives, no added sugar, and no packaging to recycle! Enjoy the wholesome goodness you've crafted!
