Pour water into mixing bowl, and sprinkle with yeast and sugar. Wait ten minutes until bubbly.

Add 2 eggs, salt, oil and half the flour. Mix (by hand or with an electric mixer with bread hook attachment) until combined. Add more flour, a little at a time, until dough is smooth and elastic.

Place in an oiled bowl, cover, and let rise one hour. Briefly knead dough, then let rise, covered, for another hour.

Divide dough into six parts, and roll each into long strands. Pinch together at one end, then braid the strands. (Alternate crossing the right strand over the three to its left, then the left strand over the three to its right.) Pinch together at the bottom when done.

Place on a cookie sheet, cover, and let rise one more hour. Beat remaining egg, and brush it over the loaf to glaze. Sprinkle with sesame seeds.

Preheat oven to 350°F, and bake approximately 45 minutes, until loaf is golden brown and sounds hollow when tapped on the bottom.
