Step 1

Add the water, oats, maple syrup (if using) and salt to a high-speed blender and blend briefly, about 20 to 30 seconds, until the mixture looks creamy. Do NOT over-blend, as this will make the consistency more slimy.

Step 2

Pour the blended mixture through a fine-mesh strainer, and tap the sides of the strainer to make sure the liquid strains through. (Don't use a spoon to press the pulp into the sides of the strainer, or the resulting milk will be slimy. This is also why you also don't want to use a nut milk bag for straining.)

Step 3

For an extra-smooth milk, rinse off the strainer and then pour the milk through it a second time. This will strain out any extra debris for an super-smooth milk.

Step 4

Use the milk right away, or store it in an airtight container in the fridge for up to 4 days.
