To make the pastry
Place 200g (7oz) flour and 100g (3½oz) butter in a mixing bowl and rub in 100g(3½oz) of butter with your fingertips until the mixture resembles fine breadcrumbs.
Stir in 15g (½oz) ground toasted walnuts then make a well in the centre and add 1 egg yolk and 1 tablespoon water. Mix to form a soft dough. Then wrap and chill for 30 minutes.
To make the filling
Preheat the oven to 200℃ (180℃ fan)/400°F/gas mark 6. Melt 50g (2oz) butter with 1 tablespoon olive oil in a 20cm (8in) frying pan. Add 750g (1lb 10oz) repared beetroot cut side down. Sprinkle with 3tbsp muscovado sugar, 2 tablespoon balsamic vinegar, 1 teaspoon chopped rosemary and season with salt and pepper.
Cook over a low heat 10 minutes. Turn the beetroot so the cut side is uppermost. Cover with foil and cook in the oven for 20 minutes or until the beetroot is tender.
Roll the pastry on a lightly floured surface to a round slightly larger than the frying pan.
Place the pastry over the beetroot and carefully tucking the edges down the inside of the pan
Bake for 20-25 minutes until the pastry is crisp and golden.
Allow to stand for 5 minutes then invert a warm serving plate over the pan and quickly flip over to turn out the tart. Serve immediately.
Notes
If you do not have a frying pan that can be used in the oven, transfer the beetroot to a cake tin after the initial 10 minutes frying (step 5). Place cut side up and drizzle all the juices from the pan over the beetroot.Make sure you use a solid cake tin and not a loosed bottom tin or all the delcious juices will run out.
