Be sure to start with good-quality butter, and make sure it’s cold before adding it to the flour. The food processor makes quick work of combining the ingredients, and the result is a buttery, flaky dough that works wonderfully in pies, galettes and tarts!
- 2 ½ cups (326g) Cassava Flour plus more for workspace
- ½ teaspoon fine sea salt
- 1 tablespoon sugar (optional; this can be omitted for savory crusts)
- 2 sticks (228g) unsalted, good quality butter (preferably a cultured or European style butter), cut into 12mm dice
- 1 teaspoon apple cider vinegar
- ⅓ - ½ cup cold water
Put the flour, sea salt and sugar, if using, in a food processor and pulse to combine.
Sprinkle the cold butter over the flour in the food processor. Pulse until the mixture looks crumbly with larger, pea-sized chunks of butter (those chunks of butter equal a flaky crust!). Drizzle the apple cider vinegar over top.
Turn the machine on and immediately start drizzling cold water through the feed tube. Stop the machine once the mixture starts to come together and looks shaggy. Give the dough a pinch—if it sticks together, it’s ready to go. If not, turn the machine on again and drizzle in a bit more water. You might not need all of the water—you’re looking for a shaggy dough, not a cohesive ball.
Transfer the dough to a lightly floured surface and shape it into a ball. Divide the dough into 2 equal pieces and form each into a flat disk. Wrap the disks in plastic wrap and refrigerate them for at least 30 minutes or for up to 2 days. Do Ahead: The wrapped disks can be placed in zip-top freezer bags and frozen for up to 3 months. Thaw in the refrigerator overnight before using.
If the dough has been in the fridge for several hours, let it sit at room temperature until slightly softened, about 10-20 minutes. Roll it out on a lightly floured piece of parchment paper. If the dough immediately starts to crack once you start rolling, it’s too cold—give it a few more minutes to warm up. If the edges crack as you roll (which they probably will, so no fear!) simply patch them as needed
Single Crust Pie
To blind bake a single pie crust: Preheat the oven to 200˚C. Transfer the dough to a 9-inch pie plate, making sure to get in the corners. Using kitchen scissors, trim the dough to a 12.5mm overhang. Fold the overhang under to form a ring around the pie plate. Crimp the ring, if you’d like. At this point, if the dough feels like it’s getting soft, pop the pie plate in the fridge or freezer for a few minutes to firm up. Prick the bottom all over with a fork. Line the crust with a large piece of parchment paper then pour in dried beans or pie weights to completely cover the bottom. Bake 15 minutes. Remove the parchment and beans. Bake 5 minutes longer, or until light golden on the bottom. Do Ahead: The crust can be blind baked up to 1 day in advance.
