If using homemade puff pastry, divide dough in half and work with half at a time. If using store bought puff pastry, use one portion at a time. Roll out dough to approximately ⅛" thick.
Lightly beat egg and water together. Brush surface of puff pastry with egg mixture.
Sprinkle one of the toppings on surface. Sprinkle with salt.
Using a pizza cutter, cut dough into long, even ½" strips.
Working with one strip at a time, pick up strip and twist both ends in an opposite direction until strip is completely spiraled.
Place on a baking sheet lined with parchment paper. Press end onto parchment paper to prevent any untwisting.
Repeat with remaining strips spacing 1" on baking sheet.
Cover baking sheet with another piece of parchment paper and refrigerate pan for 30 minutes.
Remove top sheet of parchment paper and bake in a preheated 400 degree oven for 15 minutes.
Cool on a baking rack.
