Preserve ginger with baking soda

• Prepare a box, line it with paper towels and sprinkle some baking soda on it, and place the ginger on top.
• Spread a layer of paper towels on top and sprinkle baking soda on it.
• Leave the ginger box in a cool, dry place to preserve.
• Check occasionally, if the ginger is wet, replace the paper, add more baking soda and wipe the ginger.

Preserve ginger with rice

• Use paper towels to wipe the ginger clean and dry.
• Put ginger in a rice bag and tie it tightly to preserve it. This way, the ginger will not wither or sprout.
