Method

• Preheat your oven and a baking tray, or even better, a pizza stone, to 180 °C
• Take your pastry onto a lightly floured work service – and, one inch from the edge, using the tip of a small, sharp knife, gently score to half thickness, a square within the square
• Lay out your half inch rounds of leek within this inner square leaving the boarder free
• Drizzle leeks with olive oil, scatter with flaky salt and a good grind of pepper, and finish with thyme
• Transfer to your baking sheet and bake for an initial 12min, or until edge has puffed up
• At this point reduce your oven to 150°C and bake for another 20min until leeks are tender and barely holding their shape
• Cut into quarters and serve with a grating of sharp cheddar or a crumble of feta, and a sharp green salad
