Sweet and chewy with a gooey middle and crunchy walnuts, this tart reminds me of a cross between pecan pie and a British flapjack. If you want Tara's Family Approved Pie Dough recipe (it's awesome), I suggest you buy the book. Otherwise substitute with your favourite flaky pastry recipe and adjust the bake time accordingly.
Ingredients
Tart shell
  • ½ quantity of Family Approved Pie Dough or enough of your favourite pastry to line a 23cm round pan or tin
  • 1 egg white
Filling
  • 60g unsalted butter, cubed
  • 215g light brown sugar
  • 3 large eggs + 1 egg yolk
  • 120ml maple syrup
  • 2 tsp vanilla extract
  • 2 tsp malt vinegar
  • ¾ tsp sea salt
  • 140g walnut pieces, toasted
  • 50g rolled oats
  • granulated sugar, for sprinkling
  • 80g dried sour cherries
  • Whipped cream or crème fraîche, to serve
Instructions
  1. Preheat the oven to 200 degrees C/180 C fan assisted. Grease a 23cm round pie pan or tart tin.
  2. Lightly flour the work surface and roll out your dough to a circle roughly 30cm in diameter. Gently fit into the prepared pan, folding the overhang under itself at the rim to form a nice high edge. For a neater finish, you can trim the edges once blind baked. Crimp or decorate as you like then pop the tart shell in the freezer for 10 minutes.
  3. Remove your tart shell from the freezer and prick the pastry all over with a fork. Place on a baking sheet, line with foil then bake for 15 minutes, pressing down any swells in the pastry as they rise (you'll see the foil bulge). Remove the foil then bake for a further 10 minutes, by which time the crust should be opaque and dry in places. Remove from the oven, brush over a thin layer of egg white then return to the oven for one minute more. Remove from the oven and set to one side while you make the filling.
  4. In a medium saucepan, melt the butter over a medium-low heat. Pull the pan off the heat and stir in the sugar with a wooden spoon or spatula. Briskly beat in the eggs and yolk, then the syrup, vanilla extract, vinegar and salt. Return to the stove and warm over a low heat until the mixture has loosened and is no longer gritty, about 5 minutes. Remove from the heat and stir in the walnuts and oats.
  5. Brush a second coat of egg white onto the pastry, followed by a glittering sprinkle of sugar. Scatter the cherries across the crust then carefully pour over the filling. Bake until gelled, slightly springy at the centre and with only the faintest wobble; 55 - 60 minutes.
  6. Transfer to a wire rack and cool for at least 3 hours. Serve at room temperature, rewarmed or chilled, with cream, vanilla ice cream or crème fraîche.
  7. Will keep for 2 days, covered, in the fridge.
Notes
Taken from Tara O'Brady's beautiful debut cookbook, Seven Spoons. Tara says 55 - 60 minutes for the tart but mine took closer to 50. If you're uncertain about your oven temperature, start checking the tart after 45 - 50 minutes.
