Well, I think thats the problem we were having, that the membrane hadn't been broken through. We have tried a few times already and used a few different methods of cracking the egg including the spoon method and it has still failed. There are faint marks, but not what it should look like. My grandma made them a long time ago and they worked out beautifully. She is wondering if something could have changed in the eggs we have now like a thicker membrane than before. Could that be possible that the membrane could've changed over the years or differ in size of egg?
