Homemade Little Jam Tarts are dainty little treats made of a sweet pastry dough filled with jam and finished with a lattice top. Perfect at breakfast, snack, in a lunch box, on a dessert table, for outdoor gatherings. You name it. Crumbly, light, delicious, and super cute.
In a large bowl, or in a stand mixer fitted with the paddle attachment, mix the flour with the soft butter, until you get a pebbly consistency.
Then add the sugar and, continuing to mix, add the lemon zest.
After, add the sifted baking powder and, finally, the whole egg. Mix everything until the dough almost comes together. If the dough seems too dry, add a drop of milk or water.
Pour the raggedy dough onto a work surface and gently shape it into a ball, then flatten it. This dough does not need to rest in the fridge.
Roll out the pastry dough on a lightly floured surface to about 3-4 mm. Stamp out 12 x 6.5 cm (2.5") circles using a cookie cutter to cut the pastry circles out.
Butter mini tart tins (mine were 5 cm/2"). Gently press each of the pastry circles into the pans.
Prick with a fork and spoon 1-2 tsp jam into each (I used strawberry jam and homemade kumquat marmalade).
Roll out the leftover pastry and make little ropes for a lattice top, or stampout shapes with a cookie cutter to decorate the top of the tarts. Note: you will have leftover dough, keep rolling and making more little tarts, or wrap in plastic and freeze for later use (that's what I did).
Bake at 340°F/170°C convection for about 15 minutes, or until the pastry is golden. If using regular oven, bake at 350°F/180°C.
Allow the little jam tarts to cool for a few minutes before transferring to a wire rack to cool completely, then unmold.
