On a snow day - what's a girl to do???
Make knishes, of course!
4 good size potatoes (I used russet)
2 small or 1 large onion
salt and pepper to taste
boxed pastry dough (the type that opens into a rectangle)
Grate onion and fry in small amount of olive oil.
Mash potatoes and add fried onion - mix well.
Place puff pastry on lightly floured board and put a row of filling along the long side of the rectangle. You're going to use 2 rows of filling for each rectangle so each row should be the width of about a tablespoon of filling. Gently roll pastry over to the width of about 1 1/2 times the width of the filling. Slice and repeat.
You now have 2 full rolls. Cut into equal size portions - about 6 or 8 per roll. Seal both ends and place each one on a lightly sprayed cookie sheet.
Top each knish with egg wash and bake at 350 F until golden brown - approx 30 minutes.
Note: I used 2 packages of puff pastry dough and ended up with about 6 dozen small knishes. These are a wonderful with beef or poultry.
