Paszteciki Z Pieczarkami (mushroom Rounds)

1 ea Egg white; lightly beaten
1 ea Egg yolk; lightly beaten
2 tb Butter/margarine
1/2 lb Mushrooms; minced
3 tb Half-n-half
1/4 ts Flour, all-purpose
1/8 ts Salt
1 pn Pepper, black

DOUGH 1: In a medium bowl, combine flour, egg yolk, sour cream and
water. Work into a soft elastic dough. Knead 15-20 minutes. Cover,
set aside.
DOUGH 2: In a medium bowl, combine flour, butter into a smooth soft
dough. Divide dough into 3 balls. Cover dough balls, set aside.
On a lightly floured board roll out DOUGH 1 into a rectangle about
1/4 inch thick. Place 1 ball of DOUGH 2 on center of rolled dough
rectangle. Gently press dough ball with your hands or rolling pin
until dough ball is 1/4 inch thick and covers a circular portion of
DOUGH 1. Fold up both short sides of DOUGH 1 over rolled DOUGH 2 so
ends meet in center. Re-roll resulting dough combination into a
rectangle 1/4 inch thick. Repeat with remaining 2 balls of DOUGH 2.
Roll dough jelly-roll style. Wrap dough in foil; refrigerate
overnight.
Halve dough crosswise. On a lightly floured board, roll out 1/2 of
dough into a rectangle 1/4 to 3/8 inch thick. Using a round 2 inch
cutter, cut dough rounds. Arrange 16 rounds on greased baking sheet,
allowing room for spreading. Press leftover dough scraps into a ball.
Roll to same thickness; cut as many dough rounds as possible. Repeat
r process with remaining dough until a total of 48 rounds are cut.
With a 1 inch round cutter, cut out centers of 32 dough rounds not
on baking sheets, forming doughnut shapes. Using a pastry brush,
apply beaten egg white to top surface of 1 uncut dough round on
baking sheet. Carefully postion 1 doughnut cutout directly on top of
brushed dough round. Lightly press doughnut cutout down with your
fingertips. Brush egg white on top of doughnut cutout. Place a second
doughnut cutout on top of the first. Pat lightly with your fingers.
Repeat process until all dough rounds on baking sheet have 2
doughnut cutouts glued on. Brush beaten egg yolk on top of doughnut
cutouts. Bake 15 minutes or until golden; let cool. Melt butter in
skillet, add mushrooms, saute until nearly tender. In bowl, combine
half and half, flour, salt, pepper; stir mixture into sauteed
mushrooms. Simmer 5 minutes. Set aside to cool. FIll each doughnut
round with about 1 teastpoon of cooled mushroom mixture. Bake 8-10
minutes. Serve hot.
