In a large mixing bowl, whisk together flour and kosher salt until combined, about 1 minute. Add oil and rub evenly into flour, about 5 minutes. Make a well in the center of flour and pour in 1 cup of warm water. Roughly combine flour and water with your fingers until just brought together, about 1 minute. Next, knead dough until it forms a sticky ball, about 5 minutes. Leave dough in bowl and cover with plastic wrap or a moist towel. Set aside to rest at room temperature for at least 1 hour and up to 24 hours in the refrigerator.
