400g AP flour
1/2 tsp "lievito per torte"*
The zest of one lemon.
200g unsalted butter.
1 egg + 1 yolk
13oz jar of your favorite preserves.
Measure out the flour and sugar and "lievito" directly into the food processor. Zest the lemon directly into the food processor. Give them a spin to combine.
Cube the butter and add it in, then use the food processor to cut it into mix. Here's a hint. 200g is roughly two sticks. I often reserve a tablespoon from one stick to lube the tart pan, and just cube the rest unmeasured.
Add the eggs and process them in as well. Sometimes it looks a little dry, but keep going. It will come together, usually caking up along the wall of the processor. Sometimes I knock the side of the FP with my hand to help it churn. If after a minute or so it still seems dry, toss in another yolk.
Once it comes together somewhat, dump it back into the bowl you used to measure the flour, form a dough ball and cover with a wet paper towel and set it in the fridge for 30+ minutes.
Preheat the oven to 180 degrees Celsius, approximately 350 degrees Fahrenheit. Lube the tart pan liberally. Take the dough out of the fridge and reserve a baseball sized chunk. Press the remaining dough into your tart pan by hand. No rolling required. You want a nice rim around the outside and a nice "bowl" to pour the preserves into. Speaking of which, pour them in.
Press or roll the remaining dough out on a sheet of parchment paper. Cut cookie shapes out and place them on top of the crostata. You can also roll little dough balls in your hand and press them into coin sized shapes to fill in some gaps. Heat a little water and honey in the micrwave and brush onto the cookie shapes and pie crust. Sprinkle with some coarse sugar. You can also just roll out strips and create a lattice.
Bake for 30-40 minutes.
* About that "lievito". It's an optional ingredient. I think it's basically baking soda and some vanilla flavoring, so you could just go with a 1/2 tsp of baking soda and 1/2 tsp of vanilla in the mix. Haven't tried that, but we have omitted the ingredient without trouble. I've included a picture of a small packet. I get two sometimes three crostate out of that. Check out your local Italian grocer. They'll probably have that or something similar.
Make sure you don't get the pizza yeast. This leavening is not yeast!
I've done this without a food porocessor. Proceed like cookie dough: Whisk the dry ingredients to combine, cream the sugar and butter, add eggs and zest, combine, then mix in the dry. In fact, I've probably botched every step of this process at one time or another. It doesn't seem to matter. Just keep churning with that food processor and it will all work out in the end.
Thanks for sharing, Danila!
