When making almond milk or cashew milk, I soak raw nuts on the counter overnight (about 10 hours) in filtered water (room temp). In the morning, I drain the water and whip up some milk using this recipe. You can soak nuts up to 2 days at room temp. The longer you soak ‘em, the creamier your milk will be, so experiment and see what tickles your taste buds. I also love making hemp milk with raw hemp seeds because they don’t require soaking (or even straining if you don’t mind a little texture). Most nut milks last in the fridge about 2 days, but hemp milk can last 5-7 days in the fridge.
