Q. Where do I buy fresh ginger?
You know that teenage kid in the produce department of the supermarket, the one stacking bunches of bananas on the display, the one you might not think can form a simple sentence? Ask him. Even if he can't manage the simple sentence, he can point.
Look for ginger with smooth skin if it's wrinkled or cracked, it means the ginger is old. It should also be very firm to the touch. Finally, make sure it has a fresh, spicy fragrance.
