We just made pancakes at work. Used the Delia recipe with an extra 50%, and it made 18 pancakes (a couple were too thick).
Only the brits in the office knew about pancake day, and everyone else was sceptical of lemon and sugar filling. Everyone enjoyed it though.
Yesterday was bolludagur in Iceland -- cream cake day. They make cakes like profiteroles, but with jam as well as cream inside. I am told that children get colourful sticks and they have to spank their parents with them before they get out of bed, to earn cakes (one per spank). We had the cakes at work, but decided against the spanking business.
Today in Iceland it is Sprengidagur -- which means exploding day. You are supposed to eat so much bean soup that you explode. I can think of two mechanisms by which this could be achieved.
