Put the flour in a mixing bowl and sprinkle with the salt. Warm the milk with the sugar and use a fork to dissolve the yeast in it. Knead everything together to form a firm, elastic dough. Sprinkle with flour and cover and let rise for 1 hour.
Put the sesame seeds in a soup plate. Knead the dough well with a little flour. Remove about 20 mandarine-sized pieces from the dough and shape them into a round shape. Press into the sesame seeds. Cut the rolls crosswise with a sharp knife. Do not place too close to a baking sheet and let rest for another 30 minutes.
Meanwhile preheat the oven to 225 degrees. Bake the rolls on the middle rack
