It doesn't change hop utilization enough to matter enough to where the average person could likely tell.

I was typing on my phone which is a frustrating experience so I didn't explain to the degree I usually would.
The amount of hop utilization does seem to be too minimal to notice but it does exist and thus the technical and the picky would be upset if I hadn't mentioned it. Also if one doesn't add *any* extract during the boil hop utilization is probably quite different. Which is why "late addition" proponents (of which I probably am one) usually add *some* extract at the start.

That is, if you notice the twang at all. I never have. But some folks do. At any rate, as the extract doesn't require *any* cooking and has already been thouroughly cooked, late additions will always taste *somewhat* better and fresher than early additions, which will always be somewhat technically overcooked, even if it's minimal and unnoticeable.
The only advantage to early additions is the make the directions easier to write and to follow.
And you want *some* extract early on for hop utilization. I *did* do a hop boil with *no* extract once but folks on these forums pointed out that I probably shouldn't have because of hop utilization. They are probably right. At any rate I didn't know what I was doing and I still don't know what I did, so I can't in good conscious recommend it. (Although I'm sure the beer will be quite drinkable).
Sorry noob here but what do you specifically mean at "flame out"? Is it just when you turn he heat off? Seems stupid to ask but i think i may give this a whirl. So i follow the recipe and add the DME at the time they say to and then at the very end of the boil i remove from heat and stir in the LME?
That's *exactly* what "flame-out" means. Hypothetically you can add the LME at any time, even *after* you've cooled the wort. Practically however you want the wort to be hot enough that a) everything mixes and b) everything's sanitary.
