    I've made these twice now. Both times I've doubled the amount of lemon juice in the filling. First batch I didn't add any extra flour to compensate for it - they still tasted great but were a little gooey, more pudding than cake like. Second batch I added 2-3 extra tablespoons of flour, and had 8 tablespoons of lemon juice and they were spot on!! I also included lemon zest in as it seemed a shame not to use it up. 10/10 - will definitely make again, VERY yummy!  -  03 May 2012


    Altered ingredient amounts. I will put some finely grated lemon rind in the filling mixture next time to make it more lemony.  -  17 Jun 2009
