So, with the constant craving for mint chocolate and the welcome embrace of happy tastebuds, I decided to try out this recipe: http://chocolatecoveredkatie.com/2012/03/14/mint-chocolate-fudge-pie/
I omitted the cool whip (I'm not sure there is an exact UK equivalent and I figured the pie itself would be indulgent enough) and hesitantly used a pre-made pie base as suggested. Had I more time to waste, I would have made a base from crumbled up digestives mixed with butter after the whole thing nearly collapsed in two when cutting up! However, since this only took 10 minutes to throw together, I shan't complain too much.
Note to self: leave it so set a little longer.
Would I make it again? Yes.
Thumbs up all around from me!
