Note how “empty” the pan seems once she’s done in the video.
In my experience, the browning starts after the mushrooms have released the majority of the excess water. (Unless you are really good with the “tossing them around at very high heat” technique.)

Apart from that, we’ll always be happy to take a look at what you made and come up with sage (great combo, btw) or not-so-clever advice.
