I can't say I'm familiar with it, but this still seems like a pretty easy lower just based on what zeus said. It's probably in the same ballpark as cockney, which would have to be super low on this scale.
This feels super middle of the road for me, like maybe a perfect 11. Tough enough where you can burn the bacon if you aren't careful, but easy enough where you can crack an egg in the middle of a slice of bread and generally be pleased with the outcome.
I minimized it in my first post, but there's some technique here, which is why I think it's pretty intermediate level.
Low single digits are prepackaged processed foods you just heat and serve (Canned pasta, frozen meals)
4-6 you start requiring more prep or stovetop usage (Kraft Mac & Cheese, etc)
7-10 is separate components with similar cook times - this is where I'd start considering bacon and eggs, depending on how the eggs were cooked.
Eggs scale of cooking difficulty (low to high):
Hard boiled
Hard scrambled
Hard fried
American omelet
Sunny side up
Over easy ----- we are here
Soft scrambled
Over medium
Poached
French omelet
If this were a greasy plate of scrambled eggs and Jimmy Dean sausage, I'd call it a 7. But this picture is showing a level of care taken with the food that elevates it from just bacon and eggs.
Now, we know 100% this is not >11. So, if we want to call it a 9 and make it (in my opinion, at least) harder on our competitors, then I'd be open to that. If we say 11, we either bink or give them a free point. So maybe 9 is the better play.
