Combine 200 g bread flour, 2 g salt, and 180 g water in a mixing bowl. Knead until no dry spots of flour remain. Rest at room temperature for 15 minutes. Knead and fold the dough for 3 minutes more, until smooth and elastic. Rest again for 15 minutes to relax the gluten.
Heat a skillet (not nonstick) over low heat. Lightly brush it with a thin layer of oil using a paper towel. Pick up the entire ball of dough with one hand and gently stamp it onto the skillet into a thin, 5-inch circle.
Cook the wrapper until it is no longer wet and the edges set, about 30 seconds to 1 minute. Use a spatula to lift one edge and peel the wrapper off the pan. Repeat with the remaining dough, brushing on more oil as needed.
