I just tried browning butter. I placed the butter in a saucepan and heated it. It melted, then started to bubble and sizzle. Once the sizzling subsided, brown particles started forming in the butter. The liquid itself didn't seem to change colour that much.
When the "particles" had a nice brown colour I tried the butter and it had that "nutty" flavour people often talk about. The colour of the liquid itself however was a very light brown at most.
Is this what people talk about when they say "browned butter", the "particles" inside the liquid being brown instead of the liquid itself? I also tried leaving it in the pan longer but the little particles turned black before the liquid became a deep brown (it still tasted ok though but not as good as the butter I took out before).
