Dissolve yeast in 1/2 cup warm water, then mix remaining ingredients as you would for bread with about 9 cups flour (Do not add the flour all at once; 9 cups is approximate, as with all bread many things including temperature and humidity effect how much flour you need. Use enough to make a smooth pliable nonsticky dough); knead well.
Let rise 2 hours.
Mix filling ingredients together while milk is still warm.
Spread or roll dough on table top, making sure you have no holes.
