Nigella Lawson served up a delicious dark chocolate tart with smoked salt and chocolate sandwich biscuits on Simply Nigella.

Nigella says: “I have always avoided making chocolate tarts because I have never really felt that the pastry served the chocolate, or was worth the effort. This is my simple solution: make a base out of chocolate biscuits. And the filling is just as easy to make, too. I never lie about how effortless something is to make, but no one will believe me on this one.”

The ingredients for the base: 28 oreo cookies (2 x 154g packets), 50 grams dark chocolate (min. 70% cocoa solids), 50 grams soft unsalted butter and ½ teaspoon smoked sea salt flakes.

For the filling: 100 grams dark chocolate (min. 70% cocoa solids), 25 grams cornflour, 60 ml full fat milk, 500 ml double cream, 50 grams cocoa (sieved), 2 teaspoons instant espresso powder (or strong instant coffee powder), 75 grams caster sugar, 1 teaspoon vanilla paste (or extract), 2 teaspoons extra virgin olive oil and ¾ teaspoon smoked sea salt flakes.

The recipe is taken from Nigella’s book titled: Simply Nigella: Feel Good Food, available from Amazon now.
