In a mixing bowl, whisk together flour, baking powder and salt. Add the cream cheese and butter, and using a pastry cutter, cut both the butter and cream cheese into the dry ingredients until the mixture looks like coarse, leaving some tiny bits and pieces of fat in the mix.
Add the cream, water and apple cider vinegar. Continue to mix briefly just until the mixture clumps together when pressed with your fingers. With your hands in the bowl, gather the mixture by pressing and kneading lightly, until a rough, patchy dough is formed. The characteristic of the dough is that it's no too wet that is easily gathered liked a play dough. It is somewhat crumbly, patchy but it holds together.
Place the dough into a piece of plastic wrap and flatten into a disc. Wrap the dough in plastic and knead gently with your fingers and palm to form it a bit more. Chill this in the fridge for 1-2 hours.
Take the dough out and let it rest for about 10-15 minutes. On a floured surface, roll the dough out from the center going out, going in firm but single strokes to avoid overworking the dough. Roll it out to ¼ inch thickness, and no less. The dough should be larger than your tart crust. Wrap the dough in the rolling pin. Again, this dough is delicate and patchy. Use a pastry scraper as needed to lift the dough.
Gently lower the crust to the tart pan. Ease it into the sides and leave about ¼ inch overhang on the edges. If the crust tears or is short on some edges, patch up using excess pastry on the other sides. Roll the pin over the tart pan to trim the excess pastry . Then, using your fingers gently ease the pastry into the pan edges so that there is a little bit of overhang. Chill this in the fridge for 1-2 hours.
Preheat oven to 425 ℉. Using the tines of the fork, poke holes all over the pastry. Cut a piece of parchment paper that is larger than your pan. Lay it in top of your crust and fill the the hollow with uncooked rice that extends all the way up the sides. Set the pan on a baking sheet. Bake the crust for 12 minutes. Take it out and remove the weights and parchment, then bake for another 5 minutes. Remove from the oven. The crust will be lightly browned.
