The Infinite Scallion Jar

Why buying scallions once is enough. A guide to perpetual kitchen greens using nothing but water and a sunny windowsill.

The Infinite Scallion Jar

There is a quiet magic in watching something grow from what we usually consider waste. The scallion—or green onion—is perhaps the most forgiving and rewarding entry point into this kind of kitchen circularity.

We are used to the linear path of produce: store, fridge, cutting board, compost. But many plants retain a stubborn will to live. By intercepting the root ends before they hit the bin, we create a small loop of regeneration right on the windowsill.

**The Method:** 1. Cut: Leave about an inch of white stem attached to the roots. 2. Submerge: Place the root ends in a small jar (an old jam jar is perfect). Add enough water to cover the roots but leave the top of the cut stem exposed. 3. Light: Set the jar on a windowsill that gets decent light. 4. Wait: Change the water every couple of days to keep it clear.

Within a day, you'll see the center begin to push up. In a week, you'll have harvestable greens again. You can usually get 3-4 regrowths before the flavor weakens or the root exhausts itself.

It feels less like gardening and more like a slow, polite conversation with your food.
