What you need:
1 bottle vodka (high quality is better)
Large pile of fragrant rose petals
Dash of dried hibiscus or a few fresh hibiscus petals (optional, add a red color)
Remove petals from the bud, removing the white part as well. Rinse to remove any dirt or bugs.
Place them in a quart size jar. Pack the jar full. I like to add a dash of dried hibiscus as well to create a true rose color. Pour vodka over rose petals. Fill jar to cover completely. Press petals down into vodka if needed.
Let sit for at least a week, two or three weeks is better if time allows.
