i started making my own oat milk this week. not quite there yet but good enough for smoothies. need to get an emulsifier so it doesnt separate (saw sunflower lecithin in one recipe) and probably a better strainer to reduce the chalkiness though that may need something else. still at the moment its just blending oats, water, vanilla & maple syrup and straining a couple of times. not even soaking as that tends to sliminess.
