Ingredients

1 cup old-fashioned rolled oats

4 cups cold water

1/8 teaspoon sea salt

Instructions

  1. Soak oats in cold water for at least 30 minutes (or overnight), then drain and rinse thoroughly.
  2. Combine soaked oats, 4 cups cold water, and salt in a blender. Blend for 15–30 seconds, being careful not to over-blend.
  3. Strain the mixture using a nut milk bag, cheesecloth, or fine mesh strainer. For best texture, strain twice.
  4. Store in a sealed container in the fridge. Shake well before each use. Use leftover oat pulp in other recipes.

Notes

  • Use cold water and avoid over-blending to prevent sliminess.
  • Oat milk keeps in the fridge for 3–5 days.
  • Flavor variations: add maple syrup, dates, vanilla, cinnamon, cocoa, or turmeric.
  • Do not overheat; gently warm on stovetop if needed.
  • Use certified gluten-free oats if required.
