For a real sweet treat, neenish tarts are simply the best. This batch was devoured before the day was done. Neenish tarts bring back memories of hopping off the school bus ravenous and heading for the biscuit tins, which were always full of home baking. It was a real find when these little treats were waiting. The fillings can vary a little, but I am a lemon fan, so this version is my favourite.
