I got in last night and decided that a chicken lasagne was the best match with the contents of my fridge and kitchen cupboards, only to be blown off course when I discovered that I didn't have any flour to make a bechamel sauce.
As I pondered this disaster, a vague memory that the Nutribullet I bought four months ago had come with a "milling blade" interrupted my reverie.
And so it came to pass that I ground then made a roux from my own rice flour; very good it was too as well, though I would probably sift it before cooking next time.
A new era of home made powders and pastes dawns. Be very afraid.
