Combine the water, instant yeast and sugar in a small bowl. Use a whisk to mix until the yeast and sugar dissolve. Then, let the mixture sit for about 4 to 6 minutes until it becomes foamy and blooms. After, stir in the vegetable oil and set aside.
While you are waiting for the instant yeast mixture to bloom, sift the bread flour, salt and baking soda together in a separate bowl.
When the yeast mixture is ready, add it into the bowl of dry ingredients. Use a rubber spatula to mix everything together. If the dough feels too sticky, add another tablespoon of flour at a time.
Sprinkle some flour on your work surface and begin kneading. Continue kneading until the dough looks smooth.
Place the dough in a bowl and cover it with a damp kitchen towel. Let the dough proof for 1 ½ to 2 hours in a slightly warm dark area. The dough should double in size.
Punch the down to flatten it and then portion it into 18 smaller balls. Let them sit for 5 minutes to rest.
After, flatten the dough balls into a flat circular shape, 5-inches in diameter and approximately ⅓-inches thick.
