Well, I've just sandwiched the two halves together and the top layer snapped iyswim. It's a good job it's only friends coming for a and not anyone matters! Though actually one of them wins prizes for her cakes.
It could be that Elegran, it's 15 years old - I'll have to test it! It cooks everything else ok but they dont need it to be so precise.
I made Lemon Cupcakes to take to our Quiz night, they looked great ,golden and well risen. Took one out of the case to try it and it was hollow!!!!!!!
It was as though it had dropped from the bottom up. Same oven, same temperature, same recipe just weird. It has not happened since. I made some Lemon Butter Icing and took it along so we could turn the cakes into tarts.
