My grandmother always puts a nail in the onion: I was surprised when I found out why.

💡 How to do it?
1️⃣ Use a clean, rust-free iron nail (boil it in water first to sterilize it).
2️⃣ Insert the nail into a whole onion and leave it for a few hours or overnight.
3️⃣ Remove the nail and use the onion in soups, stews, or sauces.
2️⃣ Natural Pest Repellent 🦟

This trick is also used in gardens! A nail inside an onion releases sulfuric compounds that repel insects and pests naturally. Place them around your plants to keep bugs away.
3️⃣ Extends Onion Freshness 🌱

Some people believe that placing a nail in an onion helps slow down sprouting, keeping it fresh longer.
Does This Actually Work? 🤔

Yes! This method has been used for generations, especially in countries where natural iron supplements were hard to find. It’s an easy and effective home remedy for boosting iron intake and has surprising gardening benefits too!
