Crostata di marmellata

250g plain four
70g of ground almonds
100g caster sugar
150g butter
1 egg yolk
pinch of salt
1 tsp almond essence (v important, I think!)
approx 200g of fruit jam of your choice (alternatively, use chocolate spread)
icing sugar to decorate

put the flour, sugar and ground almonds in a bowl.

add the room-temperature butter in chunks, and rub into the dry ingredients to make bread crumbs.

the tricky bit, for me at least, is bringing this mixture together into a dough you can roll out. I find that adding the egg yolk and a sprinkle of cold water helps to do this.

cover the pastry in cling film and leave in the fridge for at least 30 mins.

grease a baking sheet and cover with baking parchment.

thoroughly flour your surface and rolling pin.

cut off a third of the pastry, and set aside.

begin to roll the pastry into a roughly rectangular shape, to fit the baking tray. The thinner the dough, the better the end product. Aim for approx 3 mm.

transfer the rolled-out pastry to the baking sheet, with a little space around the edge of the tray (the jam is prone to bubble over!)

cover with a good layer of jam.

roll out the piece of pastry you set aside earlier, so that it is roughly as long as the width of the tart's base.

cut this piece of pastry into 1.5 cm, long strips.

arrange these strips in a wide crosshatch over the jam-covered base.

if you have any remaining pastry, use it to create a cornice around the tart, so that the edges of the lattice are concealed.

bake for 30 mins.

dust with icing sugar.
