No of course it won't, but if you read some of the recipe detail, things like "yeast cake" is rare as rocking horse sh1t. So obviously, you're not gonna get what was originally intended by the recipe are you.
There's no reason why you won't get something close though. It depends on analysis of the recipe i.e. why was the egg white in there in the first place ? I can't think of any other reason than clearing - like when some recipes include "Irish Moss" or bentonite. They're only there to assist with the clearing, they don't do anything else so there should be little reason why they couldn't be omitted initially and the clearing carried out by different method.
The biggest difference would be to do with the yeast anyway, so if you can't get the identical strain (which is unlikely as none of recipe state which one was actually used originally) you're not gonna get the same are you.
It's the same with JAO. The Fleischmans stuff isn't available here so I can only use the nearest equivalent - plus, as Joe comes from the US, his measurements would be in US gallons, whereas seeing "gallon", I'd automatically make a batch to 1 imp gallon, which is likely to be less sweet as there's about 3/4's of a litre difference. It still makes a good brew though, so there's probably little to worry over.....
Just my 2 cents
