6tablespooncolored sugar1 tbsp of each rainbow color
Prepare 6 different jars or ziploc bags, 1 per color (red, orange, yellow, green, blue, purple). Add 1 tablespoon of sugar to a jar / bag and then a few drops of liquid food coloring or a pinch of gel food coloring. Shake / knead until the sugar is evenly colored.Do you only have red, yellow and blue? Make orange with red + yellow, green with yellow + blue and purple with blue + red.
Roll out the fresh puff pastry. Then sprinkle 1 tablespoon of white sugar over the dough and roll the sugar with a rolling pin in the puff pastry. Then turn the puff pastry over.
Sprinkle the colored sugar over the long length (red, orange, yellow, green, blue, purple) so that you get 6 lanes over the short length.Then roll over the sugar gently with a rolling pin. Roll the long sides of the puff pastry by hand, to the center. Repeat on the other side, so that the two rolls meet in the middle (between the yellow and green sugar).
Wrap the puff pastry in baking paper or plastic and refrigerate for 30 minutes (10 minutes in the freezer if you are in a rush!).
Preheat the oven to 220 °C / 430 °F.
Remove the roll from the fridge / freezer. Cut the dough into pieces of about 1.5 cm (⅗ inch) with a knife. Place the pieces on (silicone) baking paper. Brush the baking paper with oil first (this is not necessary if you use silicone baking paper).
Bake the cookies in 15 minutes. Let the cookies cool for 1-2 minutes and then carefully loosen them with a spatula. Otherwise, they will stick due to the melted sugar.
You can also use crescent dough instead of fresh puff pastry.
