Prepare the apples: Slice the apples in half from top to bottom and remove the core from the center of the apple without splitting it. Lay the apple cut side down on a cutting board and cut the apple into slices as thinly as possible (1/16th of an inch). Place the apple slices in a bowl filled with the lemon juice plus an equal amount of water. Microwave the apples in the lemon water for about three minutes to soften them.

Prepare the dough: Sprinkle a cutting board with flour and roll out the pastry sheet as thinly as possible. Cut it into six long strips.

Prepare the jam: Mix the jam with the 1 tsp. of water and put it in the microwave for about 30 seconds. Stir to combine so that it has a thick syrup-like consistency.

Assemble the apples: Lay the pastry strips down and brush
jam over each one. Place the apple slices along the top half of each strip,
laid out like overlapping rainbows. Fold up the bottom half of the strip, then
carefully roll up each one until you have a rose.

Place the roses in greased muffin tins and bake for 35
minutes at 375 degrees. Sprinkle with powdered sugar if desired. Serve warm or at room temperature.
