Make soy milk at home with just soybeans and water. I’ll show you the blend, simmer, and strain method for a fresher taste, plus what to do with the leftover okara.
Soak the soybeans in plenty of water for 6 hours or overnight. Drain and rinse well.
Add the soaked soybeans to a high-speed blender and pulse briefly to break them up.
Add the 8 cups of water and blend until completely smooth.
Pour into a large, heavy-bottom pot. Bring to a boil over medium heat, stirring often so nothing sticks.
Once boiling, cook for 3 to 4 minutes, skimming off foam as it rises.
Reduce the heat and simmer for 15 to 20 minutes, stirring occasionally and scraping the bottom of the pot.
Turn off the heat and let cool for a few minutes. Strain through a nut milk bag into a large bowl and squeeze well.
Let the soy milk cool completely, then stir in vanilla and sweetener if using. Transfer to a clean bottle or jar and refrigerate.

Notes
Flavoring: For vanilla or sweetened soy milk, add vanilla and sweetener after the soy milk has cooled.Separation: Homemade soy milk may separate in the fridge. Shake or whisk before using.Okara: The pulp left after straining is okara. Save it for baking, soups, or veggie patties.Richer option (optional): Use 6 cups of water for a richer soy milk, or 4 cups for extra-rich (you’ll need to stir more to prevent sticking).
