Line a baking tin with baking paper and set aside. I did this quite roughly in a pretty deep, square tin. It depends on how thin you want the rocky road to be, the smaller the tin in length and width, the thicker it will be

Chop up the macadamias, marshmallows and red frogs and pop into a bowl. Ensure that the pieces of marshmallow are small enough so you don’t end up with them taking over the rocky road, which is what seemed to happen a little bit with mine! Then add the pistachios once they’ve cooled a little and the cranberries. Mix this all together gently. This is what mine looked like in a bowl:

To melt the chocolate, the recipe called for melting it in the microwave, but I personally prefer to do it on the stove. I filled a small saucepan with a little bit of water and placed a heat safe bowl over the top so there were no gaps. I then poured the chocolate melts into the bowl and over a medium heat stirred the chocolate until it melted. Sometimes, the water will boil over and you’ll need to lift the bowl. Be careful of the steam when you do this, its normally best to lift it tilting away from you. Here's a pic:

Pour the melted chocolate into the bowl with all the lollies and nuts. Mix this well to ensure everything is coated.

Pour this mixture into the prepared pan, and even it out with a spatula.

Refrigerate this for a couple of hours, or overnight if you have the time.

When you are ready to cut it, take it out of the fridge and get a nice big knife and a chopping board. I was able to cut it quite easily as it was a very hot day, but if you don’t have this on your side, simply heat the knife a little under hot water to make it really easy to cut through the rocky road. I cut mine into about 16 pieces, but yield will really depend on the thickness of your rocky road.
