Storage Tips
Unshelled water caltrops can generally be stored in a cool, dry location for up to two weeks.
Refrigeration may help extend freshness.
Once shelled, store kernels in an airtight container in the refrigerator and use within several days.
For longer storage, freezing is often recommended.

Final Thoughts
If your neighbor hands you a bag filled with strange horned pods, don’t be too quick to dismiss them.
Water caltrops may look intimidating on the outside, but inside they hide a delicious, nutritious kernel enjoyed by people for centuries.
More importantly, they represent something special: a tradition of sharing abundance and introducing others to foods they might never have discovered on their own.
So crack them open, try a few recipes, and perhaps ask your neighbor how their family prepares them.
You may end up discovering not only a new ingredient, but also a new connection and a new story worth sharing.
