Make a small slit or poke with the tip of a knife.
Push one whole clove (the spice) into the slit so it’s firmly held.
Drop the onion into your soup, stock, or sauce while it simmers.
Remove the onion before serving. (You can either discard it or chop it up — but most of its flavor will already be in the liquid.)
That’s it!
A Few Extra Tips
Don’t use garlic cloves — this trick calls for the spice clove (Syzygium aromaticum). Garlic is delicious but completely different.
How many cloves? One is usually enough for a large pot. Too many can make the dish taste medicinal.
Can I use a dried clove that’s old? Yes, but the flavor will be weaker. Fresh, fragrant cloves work best.
What about slow cookers? Absolutely. Just bury the clove‑studded onion in your slow cooker and let time do the work.
Why I Love This Trick (And You Will Too)
It’s simple. It’s old‑fashioned. And it works beautifully.
Whenever I drop a clove‑studded onion into a pot of soup, I think of my grandmother standing at her stove. No complicated gadgets, no fancy techniques — just a little piece of wisdom passed down through the kitchen.
Now you’re in on the secret too. 
Give it a try next time you make chicken soup, beef stew, or a creamy sauce. You’ll be amazed at how such a tiny thing can lift a whole dish.
