Instead of using a lime you can use an orange or lemon. You can also use ginger biscuits for the base.
Great recipe. I added extra sugar as it was a bit to sharp for my taste. Used chocolate digestives and chocolate chip cookies for the base. Yummy! - 29 Aug 2014
Really easy and delicious. I have doubled the ingredients and put it in an 8" loose bottomed cake tin. - 22 Oct 2011
