Preheat oven to 350F (180C).

Combine yeast, warm water and 1 teaspoon sugar in a bowl.

Let stand for 5 minutes to activate the yeast.

Beat eggs in a large bowl.

In a small saucepan, combine milk, salt, butter, and sugar.

Stir over low heat until milk is warm and butter is mostly melted.

Gradually stir the warm milk mixture into the beaten eggs.

Beat in 3 cups of flour until smooth.

Add the yeast mixture to the egg and flour mixture and mix well.

Gradually add enough of the remaining flour to form a dough.

Turn the dough onto a lightly floured surface.

Knead for 8 to 10 minutes until smooth and elastic.

Place the dough in a greased bowl.

Cover the bowl and let rise in a warm place for 1 to 1.5 hours, or until doubled in bulk.

Divide the dough into 4 equal portions.

Form each portion into a small loaf.

Place the loaves in greased cake pans or on a baking sheet.

Let rise for at least an hour, or until doubled in size.

Bake in the preheated oven for 20 minutes, or until golden brown.

Cool on a wire rack before slicing and serving.
