The creamy filling and fresh fruit combo in this blackberry tart is a real winner, and so easy

I must have made thousands of these tarts when I worked for Antonio Carluccio at the Neal Street Restaurant in London. We used to make them for the Royal Opera House, and people going to see an opera or ballet would have one as part of the poshest picnics in London, in their boxes up above the stage. I once went along on my day off to see Swan Lake and looked up to see all the people in the boxes eating my tarts while I was down with the others in the cheaper seats (eating a tube of fruit pastilles!). Not that I was jealous. I just knew how damn good those tarts were! This is such an easy dessert to make, especially if you have a couple of tart shells in your freezer. You can make it with just about any soft fruit – raspberries, blackberries, strawberries or blueberries, even lightly cooked gooseberries. You are in for a real treat!
