Danielle Nierenberg, President of Food Tank, shares a sustainability pro-tip in honor of Earth Day. Instead of wasting leftover pasta water by pouring it down the sink, you can save it, let it cool and use it to water your plants. The starchy H2O will give them a beneficial nutrient boost and help them grow. Just be sure to avoid using cooking water that has been salted or seasoned.
This also applies to leftover water from boiling spinach, potatoes, and hardboiled eggs, according to Reader’s Digest.
