Validation has many meanings. The most interesting context for this word from my experience was in big pharma. When scaling up a process, bringing a chemical reaction from research to manufacturing, a reaction procedure goes through a process of being tried by many others to see if it works as described. If you're the first chemist in line, the innovator, it is a humiliating process. You see your personal touch get shredded with vigor by others until it becomes reproducible. It's one of the fastest ways an experimental chemist matures.
This is what I think about when @TestKitchen or the ilk call something "Master Recipe." It rarely is. But this poached egg method, it's perfect.
So, this post is only my experience with someone else's method, a validation of sorts. The only thing - I don't know where ground zero is, feel free to chime in via comments. I don't know who created this method. I'd like to have a beer with whoever it is.
Gently spill the egg into simmering water (no vinegar needed). Let sit 3 minutes. Use screen to remove them. As they cook, they'll lift off the bottom of the pan of boiling water. The eggs will stay separated!
To serve, bake a baguette, slice in half, toast and butter.
Grab your egg out of the water with that same screen, swirl to remove excess water and plop on baguette. Enjoy. It always works. Always.
