01 - Place the raw almonds in a large bowl and cover generously with water. Allow them to soak for at least 8 hours or overnight until plump and softened.
02 - Drain the soaked almonds in a colander and rinse thoroughly under cold running water to remove any residual tannins released during soaking.
03 - Combine the drained almonds and 4 cups of fresh filtered water in a high-speed blender. Add pitted dates, vanilla extract, and a pinch of sea salt if desired.
04 - Blend on the highest speed setting for 1 to 2 minutes until the mixture is completely smooth, creamy, and no gritty almond fragments remain.
05 - Pour the blended mixture through a nut milk bag, cheesecloth, or fine mesh sieve into a large bowl or pitcher. Firmly squeeze and press to extract as much liquid as possible, reserving the almond pulp for another use.
06 - Transfer the strained almond milk to a clean bottle or jar, seal tightly, and refrigerate. Shake vigorously before each use. Consume within 3 to 4 days for best quality.
