Ingredients

For The Crust

  • 1 ¾ cup flour
  • ½ cup cold butter
  • 2 tablespoons granulated sugar
  • 1 large egg
  • 2-3 tablespoons cold water

For The Filling

  • 2 cups granulated sugar
  • ½ cup water
  • ½ cup dark golden corn syrup
  • ½ cup lemon juice
  • 1 tablespoon lemon zest
  • ¼ cup butter
  • 3 large eggs
  • 1 ½ cups breadcrumbs fresh coarse homemade crumbs work best
  • Powdered sugar for dusting

Instructions

To Make The Crust

  • In a large bowl, add the flour, butter and sugar. Use a pastry cutter to cut the butter into the flour until it resembles coarse crumbs.
    1 ¾ cup flour, ½ cup cold butter, 2 tablespoons granulated sugar
  • Add the egg and 2 tablespoons of water and stir with a sturdy spoon until it comes together, adding additional water 1 teaspoon at a time if necessary.
    1 large egg, 2-3 tablespoons cold water
  • Form the dough into a disk shape, then wrap in plastic and refrigerate for 30 minutes.
  • Preheat the oven to 400F. Roll the dough out on a lightly floured surface to be about 11” in diameter. Carefully transfer the dough to a 9” tart pan and trim the excess dough along the outside.
  • Line the pan with parchment paper, then fill with pie weights. Bake in the preheated oven for 15-18 minutes, or until the crust is lightly golden.
  • Remove the pie weights and set aside until ready to use.

To Make The Filling

  • Turn the oven down to 350F.
  • In a large saucepan over medium high heat, add the sugar, water and dark golden corn syrup. Bring to a boil, then turn down the heat until it reaches a low simmer. Allow to simmer for about 10 minutes, stirring frequently, until the mixture is amber colored.
    2 cups granulated sugar, ½ cup water, ½ cup dark golden corn syrup
  • Add the lemon juice and zest, mixture may bubble up, stir until smooth. If the syrup gets hard and does not dissolve into the lemon juice gently heat until smooth.
    ½ cup lemon juice, 1 tablespoon lemon zest
  • Add the butter and whisk until smooth.
    ¼ cup butter
  • Allow the mixture to cool slightly before adding the eggs, one at a time, whisking well after each addition. Strain into a large bowl to remove any lumps.
    3 large eggs
  • Mix in the breadcrumbs, then transfer the whole filling mixture to the prepared tart crust.
    1 ½ cups breadcrumbs
  • Place the tart pan on a baking sheet to catch any spills, then bake in the oven for 35-40 minutes, or until the filling is set but still wobbly.
  • Remove from oven and allow to cool for at least 1 hour before sprinkling with powdered sugar
    Powdered sugar for dusting

Notes

  • The mixture may bubble up when you add the lemon juice and zest. This is ok! Just stir until it is smooth.
  • If the syrup gets hard and does not dissolve into the lemon juice heat the syrup over low to medium low heat until it's smooth.
  • Let the filling cool a bit prior to beating in the eggs one at a time. If you don't let it cool a bit, your eggs will scramble.
  • Straining the filling is a must and helps ensure a silky, smooth filling.
