Your format is most certainly NOT for me. I am one of those people that do get all ingredients out first. I also get all my required measuring instruments out ahead of time. I also read the entire recipe so I can plan my steps. A normal recipe format is ideal for me. Your format is confusing to me. But everyone does things differently. I'm sure your format has an audience. Good luck.
In fact, it is much better to do what you describe. My cooking life became much easier once I learned to get a proper mise-en-place going. By the time I actually turn on a burner or anything like that, everything is fully prepped and ready to go in a pre-measured container.
I don't bake, I only cook so your specific example I don't know.
I'll also admit that when I'm dialing something in ("needs more X") that obviously that's not prepped ahead of time.
Anything else I find it easier and cleaner to just have a bowl of X ready to go. It goes in the dishwasher within minutes of using it, and my cutting board and such was already cleaned.
