1 1/4 tsp dry yeast
1/2 tsp salt
3/4 c warm water
1 egg
1 1/2 c flour
coarse salt
1 tsp sugar
mustard, if desired

Add yeast to warm water and dissolve.  Stir flour, sugar, and 
salt into a small bowl.  Gradually add the flour mixture to the liquid 
mixture.  Use your hands and work the dough until it is soft and firm but 
not sticky.  Add a little more flour if necessary - about a Tbsp or so.  
Knead dough until smooth and elastic - about 5 minutes.  Grease a 
medium-sized bowl.  Lightly grease your fingertips and place the dough in 
the bowl.  Cover with plastic wrap and refrigerate several hours or 
overnight.  

Preheat oven to 450 degrees.  Grease a cookie sheet.  Divide 
dough into 15 parts.  Roll each piece from the center out into a pencil 
thin rope about a foot long.  "Loop" each rope into the shape of a 
pretzel.  Using a pastry brush, brush each pretzel with beaten egg.  
Sprinkle with coarse salt.  Bake 10-12 minutes or until golden brown.
