Hi Angela! Thank you for this wonderful recipe. I live Zwiebelkuchen. It's been years since I've enjoyed one and this is my first time making one; I'm not that versed in custards. It looks great and tastes delicious, it is, however curdled, I think, so maybe I over baked it? I'll include a photo if I can. Any tips to what I did wrong will be appreciated. I would like master Zwiebelkuchen! 😉

Hi Carol, sorry to hear that. Could it be that the bacon mixture was too hot when you added it to the mixture?
Carol LiVecchi says
Could be. It still tasted delicious and I'll definitely make it again.
Angela Schofield says
That´s great to hear, Carol. Perhaps you start with preparing the bacon mixture and let it cool completely, this should solve the problem.
