In a food processor, pulse all-purpose flour
(spooned and leveled), baking powder, and coarse salt. Add minced
fresh sage and thyme; pulse until combined. Add cold unsalted butter, cut into pieces; pulse
until mixture is the texture of coarse meal, with a few
pea-size pieces butter remaining. Add 1 cup ice water; pulse
until dough is crumbly but holds together when squeezed
(add up to 1/4 cup water, 1 tablespoon at a time, if needed).
Turn dough out onto a lightly floured work surface and
knead just until dough comes together, 4 to 5 times.
Freeze baked empanadas up to 1 month. Warm in a 400 degree oven for about 15 minutes.
