That's interesting, as X's skinpri ck to egg white is 16mm now (was over 20mm) and we've been told to test with wellcooked egg... but strictly no raw or under-cooked egg even if he appears fine with the challenge. (plus I can't do the challenge yet anyway cos he's not coming off zyrtec any time soon, but that's a separate issue). GL with it, can't wait to hear about it
