  1. Preheat oven to 400°F and allow the puff pastry to thaw for 15-20 minutes.

  2. In a medium pan, heat about an inch of water to a simmer on medium heat then put a glass bowl that is slightly bigger than the pan (make a double boiler, here's a demo video).

  4. Stir in the chocolate chips and mix for 1-2 minutes or until the chocolate is thoroughly melted and glossy. You can put it back over the simmering water for a minute or two if you need the more heat to melt it.

  5. Once melted, stir vanilla and the table salt into the ganache (chocolate mixture) and allow to cool while you prep the puff pastry.

  6. Lay the puff pastry out on a baking sheet with a silicone mat or parchment paper. Poke holes with a fork in the middle of the puff pastry, leaving about an inch around the sides un-poked.

  7. Pour the ganache into the middle of the pastry and spread evenly to within an inch of the sides and bake 18-20 minutes until set but wiggley when you shake the pan.

  8. Allow to cool for 10-15 minutes then sprinkle the sea salt around the tart.
