[happynappies]

Hi - I'm making fairy cakes for M&T Christmas party which is tomorrow - got apron on and covered in flour and need urgent help! Nigella says use 2 large eggs. I only have medium, so do I use 2 - or do I use three? Or do I have to suspend baking operation to go out and buy large eggs?!! Many thanks - any advice greatly appreciated!

I would use 3 - a little extra shouldn't make any difference - and medium eggs look so small these days!

2 medium eggs if 100 or 125g of the other ingredients

if >125g use 3 med eggs

if in doubt use 2 whole eggs and one extra yolk
