- 1 sheet puff pastry, thawed if frozen
- 1/2 cup red seedless jelly (such as strawberry or raspberry)
- 1 egg, beaten
- 1 1/2 cups turbinado sugar ("Sugar In The Raw")
Pre-heat the oven to 350ºF. Line two baking sheets with parchment paper.
Evenly spread the jam over the top of the puff pastry, going all the way to the edges. Beginning at one long side, roll the dough up to the middle, then repeat with the opposite side, rolling it up until it reaches the middle and butts into the other roll-up.
Spread the turbinado sugar out onto a baking sheet (or the counter) and lightly brush the outside of the cookie roll with the beaten egg. Roll the entire log in the sugar, pressing lightly so it sticks to the outside. Using a sharp knife, slice the cookies 1/4-inch thick and arrange them on the baking sheet (just push them back to their original shape if they begin to come apart).
Bake the cookies until light golden brown, about 20 minutes. When the cookies come out of the oven, immediately (and carefully) remove them from the parchment paper to a clean sheet of parchment. Cool the cookies completely before serving.
