At our house, we’re getting much better with storing and using up produce. In fact, we’ve all but completely stopped throwing rotten produce into the garbage. Now, I’m taking it further by actually regrowing vegetables from scraps — in the kitchen window! It’s like my inner gardener has come out to play, and not a moment too soon as grocery prices soar and inflation in the U.S. has now reached a 20-year high.

Let’s start with scallions (green onions). They’re extremely useful, deliciously versatile and dirt cheap. Invariably, I either fail to use them up completely before they go bad or I run out, prompting quick trips to the market, which exposes my impulsive self to at least a few unplanned purchases. But no more now that I have a tiny crop of fresh scallions growing on my kitchen windowsill. It’s so easy to keep the white ends in a glass of water where they sprout and regrow into new, fresh scallions.

Here are some simple steps to regrow scallions:

No. 1: Stand the white parts of the scallions, with the wispy root ends down, in a glass or jar.

No. 2: Add water to cover the roots.

No. 3: Set the container in a sunny window.

No. 4: Change the water every day or two.

In a week or so, you can begin harvesting the green ends of the scallions, depending on how much green you started with. Snip what you need with a pair of kitchen scissors (you can take up to 70% of the green part) and leave the rest to keep growing. The green part of the scallion will regrow itself. You’ll save money and frustration, and have yourself a fun, low-maintenance and edible windowsill pet.
