Mix warm water (105-110°F) with yeast and let sit for 5 minutes until foamy. Add bread flour and salt, then knead for 8-10 minutes until smooth and elastic. Cover the bowl and let the dough rise for 60-90 minutes until doubled in size.
2.25 tsp active dry yeast, 1.25 cups warm water, 3.5 cups bread flour, 1.5 tsp salt
Divide the risen dough into 6-8 equal pieces and roll each piece into a 15-inch rope. Overlap the ends by 2 inches and press firmly to seal into rings. Cover the shaped rings and let them rest for 15 minutes.
3.5 cups bread flour
Mix molasses with 1 cup water in a shallow bowl. Dip each dough ring completely in the molasses water, then press both sides into sesame seeds on a plate. Place the coated rings on a parchment-lined baking sheet.
2 tbsp molasses, 1 cup water, 1 cup sesame seeds
Bake the simit rings at 400°F for 15-20 minutes until deep golden brown. The crust should sound hollow when tapped on the bottom. Rotate the pan halfway through baking for even browning.
Cool the baked rings on a rack for 20 minutes before slicing horizontally. Fill each ring with crumbled cheese and chopped olives. Serve warm or at room temperature.
8 oz white cheese, 0.5 cup olives
