Tomato and tapenade tart

Slice the bull’s heart tomatoes into thick 1 cm rounds. Transfer to a sieve suspended over a bowl and season well with salt. Leave the tomatoes for a good half hour to allow the juices to drip into the bowl. This will prevent your pastry becoming soggy if the tomatoes hold a lot of juice. 

To make the tapenade, put all the dry ingredients in a blender. Blitz well. Add the wet ingredients and blitz further until everything is fully incorporated. The tapenade should be very smooth. Preheat the oven to 180°C fan/200°C/gas mark 6. 

Next, roll out – or simply unfurl, if pre-rolled – the pastry to a rectangle to fit your largest, flat, heavy-based baking tray. Cut a rectangle of parchment paper to the same size, then place the pastry on top. Score a 2 cm border all around the edges of the pastry. This pastry border will puff up around the filling. Put the baking tray in the oven to preheat for 10 minutes. 

To assemble the tart, top the pastry inside the scored border with a generous smearing of tapenade. Arrange the sliced tomatoes in a single layer over the tapenade. Halve the small tomatoes, season with salt, and use them to fill any gaps. Drizzle the tart filling with olive oil and grind over some black pepper. 

Remove the hot tray from the oven, slide in the tart on the parchment paper and return the tray to the oven. Bake the tart for 30 minutes, or until the pastry borders are puffed and crisp, the base is a light golden brown (lift the tart tentatively with a spatula to check) and the tomatoes are soft, squidgy and just started to take on a little colour. 

Remove the tart from the oven, season lightly with a little flaky sea salt and black pepper, and scatter over the torn basil leaves. Allow the tart to cool on its tray, then slice into squares while still just warm. Drizzle with your best olive oil before serving.
