I pretty much agree with the description of the flat white. But I am not so sure about the pouring from the bottom of the jug thing. Surely you can get a very creamy flat white without using a spoon to hold the foam back?
I prefer to pour a flat white from a small milk jug which has been textured properly into a 5.5 oz cup or so with a single espresso. Milk not too hot, around 60-65 C. Just a half cm of foam so you drink through the creamy foam.
That is in my eyes a good flat white.
But then again… I am a Dutch man not a Australian 🙂
