Always buy lemons which are fragrant and have nice, oily, yellow skin without any blemishes and spots or are hard and wrinkly.
Microwave the lemons for 10 secs if you have taken out straight from the fridge..this ensures enough juice from the lemons.
While removing or grating the zest do not remove the white membrane or the pith as it tastes bitter and will affect the taste of the cake.
Drizzle the frosting on the cake while the cake is a little bit warm…that helps the cake in soaking the frosting and gives a crusty glaze and nice crunch to the cake.
