Dave's Childhood Favorite- Jam Tart

Dave has been bugging me since we got married to make him this infamous Jam Tart that his mum used to always make for them when they were kids. Through numerous testing and searching.. I have found it!!
He loved it, just about finished the whole tart himself... so I thought I would share this super easy recipe and see what you others(kiwis) think of it!

Jam Tart Recipe
9 tablespoons (110g) unsalted butter, at room temperature
1/2 cup (100g) sugar

1 large egg
1 large egg yolk
1/8 teaspoon almond extract
1 1/2 cups (190g) flour
1/2 cup (70g) stone-ground cornmeal or polenta
1/2 teaspoon sea salt
2 teaspoons baking powder (preferably aluminum-free)
1 3/4 cups (450g) apricot, raspberry or other jam

coarse raw sugar; known as cassonade, turbinado, or demerara sugar, for finishing the tart

1. Beat together butter and sugar until well-combined. Mix in the egg, egg yolk and almond extract.

2. In a separate bowl, whisk together the flour, cornmeal, salt, and baking powder. Gradually add the dry ingredients, just until the mixture just comes together.

3. Measure out 11 ounces (300g), which is about 2/3rd of the dough if you don’t have a scale, pat it into a disk, wrap it in plastic, and chill it. Take the remaining dough and roll it into a log about 2-inches (5cm) in diameter, wrap it and chill it, too

4. Remove the dough from the refrigerator and allow to room temperature slightly. With the heel of your hand, press the dough into the bottom and sides of an unbuttered removable bottom tart pan (one that’s 9″ or 10″, 24cm), or springform pan, patting it evenly.

5. Spread the jam evenly over the dough.

6. Remove the log of dough from the refrigerator and slice in cookie-sized disks, then lay them over the jam. Top very generously with lots of coarse raw sugar, at least 2 tablespoons.

7. Bake until the pastry is golden brown. (If you don’t trust yourself, or your oven, Luisa’s recipe says 20-25 minutes.) Let cool before serving, and serve at room temperature.

I would insert a picture here of what mine looked like, but I took it out of the oven and when I came back to check on it, it was already being devoured.
