Recipe Notes and Guidance
See How to Make in the Post for More Detail
You can use a microwave to melt the chocolate.
Be sure to allow the chocolate to cool before adding the marshmallows.
Let the baking paper hang over the sides of the tin, this makes it easy to remove the set rocky road in order to slice it.
Feel free to experiment with extra additions or omissions to the additional ingredients.
