Ingredients

  • Filling
  • 300g Golden caster sugar
  • 250ml Double cream
  • 200g Salted butter
  • 150g Dark chocolate (at least 70% cocoa solids)
  • ¼ tsp Sea salt
  • Pastry
  • 175g Plain flour
  • 15g Icing sugar
  • 90g Salted butter, chilled and cubed
  • 1 Egg yolk

Method

  1. Briefly pulse the flour, icing sugar and a pinch of salt in a food processor. Add the butter and blitz until it resembles dry breadcrumbs. Add the egg yolk and 4 tsp chilled water; pulse again to bring it together. Chill for 30 minutes.
  2. Preheat the oven to 180°C/gas 4 and put in a baking sheet. Roll the pastry out to a thickness of ½cm. Use it to line a 24cm tart tin, leaving a little pastry overhanging all the way round. Prick the base all over with a fork and put the pastry case in the freezer for 15 minutes.
  3. Line the tart with greaseproof paper and baking beans; slide it onto the baking sheet and cook for 15 minutes; remove the paper and beans and cook for 10 minutes further. Cool for 10 minutes then trim the excess pastry to neaten.
  4. Put the sugar in a heavy-based frying pan with 1 tbsp water; heat until the sugar dissolves but do not stir. Increase the heat and boil until it turns amber. Add 200ml double cream (the mixture may splutter); stir in 175g butter. Simmer for 3 minutes. Pour into the pastry case and cool for 30 minutes.
  5. Melt the chocolate in a heatproof bowl over a pan of simmering water. Stir in the remaining butter and double cream. Drizzle onto the caramel. Use a spatula to swirl both mixtures together; chill for 6 hours to set. Before serving, sprinkle over the sea salt.
