Not all ginger roots are created equal. You want a piece that is plump, firm, and looking vaguely energetic—avoid any that are shriveled or wrinkly like a forgotten raisin. Look for “eyes” on the rhizome; these are the small bumps or little nubs that look like tiny horns. You need these, because that is where the green shoots will emerge.
A fun fact: Ginger is a tropical plant, so it doesn’t do well with frost or fear. It’s a jungle baby at heart. If you live in a cold climate, just remember your ginger is dreaming of Bali weather (read: warm and humid).
