Edible Flower Ice Cubes
Here's a cool new way to savor the beauty of flowers: Freeze them in ice cubes to brighten drinks.
To suspend flowers in the cubes, work in layers:
Fill an ice tray (one that makes large cubes so the ice will last longer) a quarter of the way with water, add flowers facing down, and freeze.
Add more water to fill halfway, and freeze.
Fill to the top, and freeze again.
For ice that's especially clear, use distilled water that has been boiled and then cooled.
This limits impurities and air bubbles, which make ice cloudy.
