2 pk Dry yeast
          Sugar
 1 1/4 c  Lukewarm milk
          Flour
     2 ts Salt
   1/2 c  Butter, softened
CHEESE FILLING
     1 lb Muenster Cheese
     2 tb Butter
     1    Egg, beaten
 Sprinkle yeast and 1/2 teaspoon sugar over milk in small shallow bowl.
 Cover with plastic wrap and place in warm place until yeast blooms and
 mixture nearly doubles in vol- ume, 5 to 10 minutes. Combine 4 1/2
 cups flour, 1 tablespoon sugar and salt in large mixing bowl. Make
 well in flour mixture and add milk-yeast mixture and softened butter.
 Beat vigorously with large spoon until smooth.  Form into ball and
 place on lightly floured surface.  Knead hard 10 minutes, adding more
 flour or water as needed to create medium stiff dough. When dough is
 smooth and elastic, place in large, lightly buttered bowl. Cover with
 plastic wrap and kitchen towel and let rise in warm, draft-free
 place, such as unlit oven with pilot light on, until doubled in bulk
 and dough springs back slowly when gently poked with finger, 45
 minutes to 1 hour. Punch dough down and let rise until again doubled,
 30 to 40 minutes. Punch dough down and roll out on lightly floured
 surface into circle about 22 inches in diameter. If rolling surface
 is too small, divide dough in half and roll into 2 half-circles 22 by
 11 inches. Roll dough up on rolling pin and unroll carefully over
 buttered 9-inch cake or springform pan or springform so that it is
 centered, with edges overlapping more or less evenly on all sides. If
 using 2 half circles of dough, form 1-inch seam to make whole circle
 and moisten thoroughly to seal. Carefully press center of dough down
 to bottom of pan. Place cheese filling on dough and bring up edges of
 dough over filling, forming thick, fabriclike folds. Moisten edges at
 top and seal. Let stand 10 to 15 minutes. Bake at 375 degrees in
 center of oven, on foil in case filling leaks, until golden brown, 50
 minutes to 1 hour. Cool 1 to 2 hours before serving. Makes 12 to 16
 servings.
                  Cheese Filling In large mixing bowl, combine cheese,
 butter, and egg. Knead vigorously until mixture is uniform. Shape into
 thick, round cake 8 to 7 1/2 inches in diameter.
