Preheat oven to 400°F.
Combine the flour, baking powder and salt in the bowl of a food processor and pulse to combine. Add any flavourings you like and pulse until chopped and blended in with the remaining ingredients. Add the oil and pulse until the mixture resembles coarse meal. (Alternatively, blend everything together in a bowl with a spatula or whisk.)
With the machine running, pour 1/2 cup of cold water or milk through the feed tube and pulse, adding extra if you need it until the dough starts to come together. This will depend on your flour and what flavourings you added; I usually need 1/2 cup plus about 2 Tbsp. of liquid.
Tip the dough out onto a lightly floured surface, gather it into a ball and let it rest for about 10 minutes. Roll the dough out about 1/4” thick, sprinkle it with salt (if you like), and roll lightly to help the salt adhere. Cut into 1/4”-1/2” wide strips as long or short as you like, then twist the strips and place them on an ungreased baking sheet, pressing the ends lightly onto the sheet if they start to unravel. Bake for 12-15 minutes, or until golden.
Makes about 2 dozen breadsticks.
