PS, I don't think I refrigerated overnight--
the whole point is to let the miso work on the oats and it breaks them down, while the B12 increases.
I used steel cut oats, you can use quick cook too, this would makes a milder and less "whole food" milk, obviously.
I'm also going to try this with soaked whole oat groats,
sprouting them, then blending with the miso, letting it sit, maybe strain it. maybe not... :-)
