Exactly-- my egg tolerance wasn't that high until I was more or less "outgrown" either.
I over-rode our allergist's advice "just make it the way you should in a regular recipe" and discussed with him the fact that I was
so wanting at least-- a STARTING point-- as a result of a challenge.
Hitting DD with 300 mg of egg protein in a single dose didn't seem to me to be a good way of doing that. At all. Not given what I knew about her reaction history (which was even fairly recent, at the time) and the fact that she so consistently reacted to shared lines even when they'd been STEAM washed (like in pasta production).
So that's why with this-- we did it MY way. Allergist actually agreed with me, and in truth I think he was just afraid to ask (or maybe hadn't thought all of the math through himself)... but at any rate, when I showed up with a paired set of challenge foods and a concentration of egg in the experimental side, he was obviously elated. His exact words were "It feels just like being back at Sinai with the dieticians providing all these neatly measured doses!"
Anyway. Long story short, I'll give you the link to all of the gory details.
Baked egg challenge...(CMdeux's DD)Be sure to read that all the way through. My DD is very definitely still allergic to egg, from what I can tell-- though (and this ought to give ANY parent pause) we may have to do another challenge because
she is beginning to doubt the nature of that allergy and I fear that she will begin to take risks as a result.
I haven't yet discussed that part of things with our allergist, but it's on the agenda for this spring. I think we're going to try to do a number of challenges this summer.
