method

  1. For the dough, stir the rice flour, sorghum flour, tapioca starch, sugar, salt and spices to combine. Cut in the butter until the whole mixture has a rough, crumbly texture but there are a few larger bits of butter visible. In small dish whisk the eggs, water and vanilla. Add this to the flour mixture and stir until the dough comes together. Shape the dough into a disc, wrap and chill for just 15 minutes, to chill the butter.
  2. While the dough is chilling, prepare the filling by stirring all of the filling ingredients together until evenly blended.
  3. Preheat the oven to 375°F. Lightly dust a 9-inch pie plate with rice flour and dust a rolling surface with rice flour for rolling. Gently roll out the pastry (dusting your rolling pin and the dough as needed) to a diameter of about 14-inches and lift it into the pie plate. Spoon the fruit filling into the shell. Gently fold the edges of the pastry (about 2 inches/5 cm) over the fruit filling – it usually takes about 6 folds. Brush the top of the pastry with the egg wash and sprinkle with turbinado or demerara sugar. Bake the galette for 35 to 40 minutes, until the crust has browned evenly and the fruit filling is bubbling. Cool for about an hour before slicing.

The tart can be served warm, at room temperature or chilled.

PIE DOUGH NOTES

Rice flour is quite neutral in color and taste. Sorghum flour has a mild nutty taste and is more of a dove color.

I intentionally selected the rice flour, sorghum and tapioca due to their workability and taste but also their affordability, since some gluten-free elements can be costly.

Unlike a traditional flour pastry dough that has to rest to relax the glutens in the flour before rolling it out, a gluten-free pastry dough needs to chill to set the butter and to allow the rice and sorghum flours to absorb some of the liquid for easier rolling.

To make this recipe sugar-free, simply eliminate the brown sugar from the crust (no replacement) and replace the brown sugar in the filling with ½ cup of agave syrup.
