Caramelized Onion, Gruyere, Tomato Tart
Serves 6-8
Pie Dough:
========
Makes 2 disks of dough. Each one fits an 11 inch (28cm) tart or 9 inch (23 cm) pie pan
212g unbleached all-purpose flour (for the food processor)
2 tsp Diamond Crystal Kosher salt (or 1 tsp Table Salt or 5.7g of any salt using 0.01g precision scale)
26g (2 Tbsp) granulated sugar
284g (2.5 sticks) cold unsalted butter sliced 1/4 inch (1/2 cm) thick, and chilled for 15 min
142g unbleached all-purpose flour (in a large bowl)
57g cold water
57g cold vodka
Process 212g of flour, salt and sugar in a food processor for 15 seconds. Add the butter and pulse until the consistency of finely grated parmesan cheese, about 15 one second pulses. Add the mixture from the food processor to a bowl with 142g of flour and mix thoroughly with a large spoon (about 60 seconds). Add the water and vodka and mix until the liquid is absorbed. Squeeze with your hands until you get a lumpy dough (it will be crumbly). Remove half from the bowl. Form the first half into a disk and wrap tightly in plastic, repeat with the second half. Refrigerate overnight or up to 5 days or put into a freezer bag and freeze indefinitely. If freezing, move to the fridge 24 hours before using.

Rolling out the dough and blind baking:
==============================
Roll out 1 disk of dough as shown in the video (save the other one for future use), fit into an 11 inch (28cm) tart pan with false bottom, chill for 30 minutes (longer is fine). Preheat the oven to 350F (175C) with the racks in the top and bottom third. Place the tart onto a parchment covered baking sheet. Line the tart with parchment paper and fill with dry beans or some other weight (about 2 Lb / 900g or as needed). Fold the paper around the edges (use foil in places where paper is not sufficient). Bake in the bottom third until the edges are golden, about 40 minutes. Remove the parchment with beans, poke gently with a fork and place in the top third until the dough is set on top, about 10 min.
Fillings and Assembly:
=================
Caramelized onions • Caramelized Onions (cooked and chilled)
In the above video, I cook 3 Lb (1360g) of onions. If you want to make exactly the amount you need for the tart, cook 2 Lb (900g) of onions (reducing oil, salt, and vinegar appropriately),
110g grated gruyere cheese (buy roughly 0.3 Lb / 136g cheese to account for the rind)
454g cherry tomatoes, halved (or campari tomatoes, quartered)
Raise the oven temp to 375F (190C). Put tomatoes into a medium bowl, mix with 1 Tbsp of caramelized onion oil/juice and a pinch of salt. Cover the bottom of the tart with the onions, then cheese, then tomatoes. Bake in the top third until tomatoes are golden brown, 30-40 min. Cool until comfortable to handle and serve. Can be stored at room temp for a few hours and rewarmed at 350F for 10-15 min.
