Slice the apple along one side, avoiding the core.
Cut the sliced portion in half.
Using a mandoline (be careful!), thinly slice the halves.
Place the thin apple slices in a microwave-safe bowl.
Sprinkle sugar over the slices.
Pour enough hot water to fully cover the apple slices.
Microwave for 30–60 seconds, or until the slices become soft and pliable.
Let them cool slightly.
Arrange the slices in a row, overlapping them slightly with the red skin facing up.
Start with the smaller slices.
Roll the small slices tightly to form the rose center.
Place the rolled center at the edge of the medium slices, and continue rolling.
Repeat with the larger slices until you form a full rose shape.
Gently place the finished rose in a teacup.
Pour in a hot drink of your choice, like green or black tea.
Sweeten the tea with honey if desired, and enjoy as the rose gently blooms.
