In a small mixing bowl, combine yeast and water, stirring until dissolved. Add 2/3 cup of flour and beat till smooth. Cover with a towel and set aside until doubled and bubbling about 45 minutes.
In a large mixing bowl, blend milk, sugar, salt, lemon rind. Stir in butter and eggs. Beat in yeast mixture and 4 cups of flour until smooth. Gradually, add enough flour to make a SOFT, workable dough. (You might need less if using bread flour).
Turn out and knead until satiny about 15 minutes. Place dough in large greased bowl ( I use two large bowls because this dough rises a lot.).
Cover loosely with plastic wrap and towel. Set in a warm, protected spot overnight.
Next morning punch dough down, knead 3 minutes, cover and let rest 10 to 15 minutes.
Shape into rolls or braids or pan bread or Paska.
Place on a greased sheet or pans or (coffee cans for paska)(fill paska 2/3 full).
Butter coffee cans well and sprinkle with fine bread crumbs. I like to spray pans with vegetable spray and sprinkle with bread crumbs. Let dough rise for about 30 to 40 minutes.
Brush with egg wash. Bake 350 degrees for 35 to 40 minutes or until brown. Remove and cool on a wire rack.
