For the dough:
170g unsalted butter, cubed, at room temperature
1/2 cup (70g) icing sugar
1/2 teaspoon salt
3/4 teaspoon vanilla extract
grated zest of half a lemon
1 3/4 cups (250g) flour
For the apricot filling:
2 cups (8 ounces, 230g) dried apricots
1 1/2 cups (375ml) water
1/2 cup (100g) sugar
3 tablespoons (60g) honey
pinch of salt
For the crumb topping:
1/2 cup (70g) flour
1/2 cup (95g) packed dark brown sugar
pinch of salt
3 tablespoons (45g) unsalted butter, cubed, chilled
1. Line a square pan, leaving an overhang on two sides of the pan.
2. Make the dough by creaming the butter with the icing sugar and salt in the bowl of a stand mixer, or by hand, until it’s light and fluffy. Add the vanilla, and lemon zest then gradually add in the 1 3/4 cup (250g) flour, mixing until the dough is smooth.
3. Transfer the dough to the prepared baking pan and pat it flat into the bottom of the pan using lightly floured hands. Refrigerate the dough-lined pan for at least 30 minutes.
4. Make the apricot filling by combining the apricots, water, sugar, honey, and a pinch of salt in a medium saucepan. Simmer over low heat for about 45 minutes, or until all the liquid has just about been absorbed. Let cool for a few minutes, stirring, then puree in a food processor until smooth.
5. Preheat the oven to 350ºF (180ºC).
6. Bake the shortbread for 25 to 30 minutes, until golden brown. Once baked, let the shortbread cool to room temperature.
7. Make the crumb topping by mixing together the 1/2 cup (70g) flour, brown sugar, salt, and butter in the bowl of the stand mixer, with the paddle attachment, until the mixture just barely starts clumping together.
8. Spread the apricot filling over the shortbread in the pan evenly, then top with the crumb topping and bake for 20 to 25 minutes, until the topping is browned.
9. Remove from oven and let bars cool completely in pan.
To slice, lift the bars out of the pan by grasping the edges of the paper. Slice into squares.
Storage: The bars can be stored at room temperature or in the refrigerator for up to three days.
Variation: For those of you wishing to use a different dried fruit, the yield on the apricot paste was 2 cups (about 500g), in case you wish to make a substitution.
