Dissolve yeast in warm water in a large bowl.

In the same bowl, stir in lukewarm milk, 3/4 cup sugar, 3 eggs, and salt.

Add softened butter and 3 cups of flour to the mixture.

Beat the mixture until it is smooth.

Gradually stir in the remaining flour until the dough becomes easy to handle.

Turn the dough out onto a lightly floured surface and knead for about 5 minutes, until smooth and elastic.

Place the kneaded dough in a greased bowl and let it rise in a warm place for approximately 1 to 1.5 hours, or until doubled in size.

Punch down the risen dough and divide it into two equal halves.

Shape each half into a slightly flattened round loaf.

Place each loaf into a well-greased round 9" x 1 1/2" pan.

Cover the pans and let the loaves rise until doubled in size, which should take about an hour.

Preheat oven to 350°F (175°C).

In a small bowl, beat 1 egg for the glaze.

Brush the beaten egg over the tops of the loaves.

Sprinkle 1 teaspoon of sugar evenly over the glazed loaves.

Bake in the preheated oven for approximately 35-45 minutes, or until the loaves are golden brown.
