I don’t think I have. I had an allergy to eggs and avoided them most of my life. Got tested a few years back (getting flu vaccines was difficult due to it being cultivated on egg) and turns out it must have been a childhood allergy. I’m now slowing entering the world of eggs.
I haven’t boiled an egg but I have tried one. The white part was nice but the yolk made me gag. The texture didn’t agree with me.
I’m still allergic to eggs so have also never boiled one. Fortunately to me they look and smell rank so I don’t feel like I’m missing out on much.
