It can be a bit difficult cutting the slice, as the chocolate tends to crack. To avoid this, you can either score the chocolate lightly just before it sets firmly, and then slice it properly once set. Or, once it’s set you can bring the slice out of the fridge for about 10 minutes (i.e. take the chill off) before slicing with a warmed, dry knife (clean the knife after each cut).
