Shell and chop your nuts. Set aside.
Line an 8 inch pan with parchment paper.
Combine your chocolate, sweetened condensed milk and butter in a heat proof glass bowl and place over top of a saucepan with simmering water on the stove. I found keeping the stove at a medium-low setting worked for me.
Stir frequently until your chocolate melts.
Keep stirring until it is smooth. It will also feel thick.
Remove the bowl from the heat and add your pistachios and dried cherries, and also your vanilla. Mix well.
Now pour the mixture into the pan and smooth it out.
Let it cool to room temperature.
Now stick it in the fridge for a couple of hours.
Once it is set you can remove it and cut into squares.
Serve with a smile.
