Koulouri is a traditional Greek bread, similar to a bagel, but with a crisp crust and soft, chewy interior. It is encrusted with sesame seeds for added flavor and texture. This bread is a popular street food and is often eaten as a quick snack or breakfast item.
In a large bowl, dissolve yeast and sugar in warm water. Let it sit until frothy, about 10 minutes.
Add half of the flour, olive oil, and salt to the yeast mixture. Stir until combined.
Gradually incorporate the remaining flour until a dough forms.
Turn the dough onto a floured surface and knead until smooth and elastic, about 10 minutes.
Place the dough in an oiled bowl, cover, and let rise in a warm place until doubled in size, about 1 hour.
Punch down the dough and divide it into 8 equal pieces.
Roll each piece into a long rope, then join the ends to form a circle.
Dip each dough ring first in water and then coat generously with sesame seeds.
Place on a baking sheet lined with parchment paper.
Preheat the oven to 180°C (350°F).
Let the dough rings rise again until puffy, about 20 minutes.
Bake in the preheated oven for 20 to 25 minutes until golden brown.
