Ok. I tried to posh up the name when all I did was smear my favourite diabetic shortbread dough into a silicone Madeleine tin. Can't blame a girl for trying right?
Replace the orange zest with the zest of one lemon and two drops of good lemon extract. Decrease the baking time to 15-18 minutes dependant on the size and depth of your Madeleine tin. I baked mine for 16 minutes. The recipe made 14 shells in total.
