Crunchy, buttery pastry. Creamy salty-sweet caramel. Melt-in-the-mouth dark chocolate ganache. The three elements that make up this perfectly decadent chocolate tart. Well, I say its perfect but it does have one flaw… all the setting time required before you can actually eat a slice! So if you are planning to serve this as a show-stopping after dinner dessert, then best you get cracking with it in the morning.
