Dissolve yeast and sugar in warm water. Stir in the flour and knead for 8 to 10 minutes. Cover and let rise in a warm place until doubled in
bulk.

Punch down and form into 12 small balls. Roll each out into a sausage shape, then form into pretzel shape. If desired, brush with beaten egg
yolk and sprinkle with coarse salt. Allow to rise until not quite doubled. Bake at 475 degrees F for about 10 minutes.
