Mix salt, flour and egg. Add water. Mix dough quickly with a knife, then
knead on board, stretching it up and down to make it elastic, until it leaves
the board clean.
Toss on a small, well-floured board. Cover with a hot bowl and keep it warm
1/2 hour or longer.
To stretch the dough, have materials for filling ready before stretching.
Work quickly. Lay dough in center of a well-floured tablecloth on table about
30 x 48 inches. Flour dough. Roll into a long oval with rolling pin.
with 1/4 cup of the melted butter. With hands under dough, palms down, pull
and stretch the dough gradually all around the table, toward the edges, until
it hangs over the table and is as thin as paper. Cut off dough that hangs over
edge and drip 1/4 cup more butter over surface of dough.
To fill, roll and shape, sprinkle filling over 3/4 of the greased stretched
dough. Fold a little of the dough at one end over the filling. Hold the cloth
at that end high with both hands and the strudel will roll itself over and over,
like a large jellyroll. Trim edges again. Twist roll into a greased 16 x 11-inch
pan or cut into 3 strands and lay them side by side in pan.
To bake strudel, brush top with more melted butter.
Bake at 400 degrees
F for 1/2 hour.
Reduce oven temperature to 350 degrees F and bake 1/2 hour longer, or until
brown and crisp.
Brush well with butter from time to time during baking, using all together
about 1 cup melted butter for the strudel with its fillings.
