Place the flour, yeast, and salt in a large bowl and then add the water gradually. Mix them together with your hand to form a dough.
Knead it for a few minutes, until you get a smooth and elastic dough and it doesn't stick to your hand anymore. (You can use a stand mixer with a dough hook for this step).
Cover the bowl with a clean kitchen towel or cling film and let it rise for 1 hour or until it doubles in size. The rising time depends on the temperature of the room.
If you don't have toasted sesame seeds, you can toast them while the dough is rising. Simply place them in a large non-stick pan over medium-low heat, stirring constantly, and toast until they turn golden brown, 20-25 minutes. When cooled down, place the toasted sesame seeds on a separate large plate, and set them aside.
In a medium-sized bowl, whisk together the molasses and water, and set it aside.
After an hour, check the dough and transfer it to a floured surface if it doubled the size.
Shape it into a log, cut it into 12 equal pieces and turn them into balls.
Grab two dough balls and roll them into a cylinder length of 40cm/16".
Put them parallel to each other and stick the ends by pinching.
Twist them in opposite directions to make a braid and shape it into a circle.
Dip the simit ring into the molasses mixture making sure it's covered on both sides and then put it into the sesame seed plate. Make sure it is fully coated.
Transfer it onto a parchment paper-lined baking sheet and repeat the same with the remaining dough balls.
Preheat the oven to 230° C (450° F) and let the dough rings rest for another 20 minutes.
Place the baking sheet in preheated oven and bake for 15 minutes.
Lower the heat to 210° C (410° F) and bake for another 5 minutes, until golden brown, fully baked, and crispy.
