At first glance, poking cloves into an onion may seem like something out of an old kitchen grimoire. A slightly retro, almost decorative gesture. And yet, behind this rustic image hides a frighteningly effective trick, passed down from generation to generation. In the kitchen as well as at home, this simple combination has more than one trick up its sleeve… and might well surprise you.
The studded onion: a well-kept secret of French cuisine
If this practice intrigues you, you should know that it is far from improvised. In France, it is called the onion clouté: a peeled onion in which 4 to 8 whole cloves are inserted before adding it to a simmered dish.
Why make it so complicated? In reality, it is quite the opposite.
This technique allows you to delicately perfume:
- Chicken broth
- A vegetable soup
- A béchamel sauce
- A family stew
Instead of dispersing the spices in the preparation, the cloves diffuse their aroma slowly and evenly during cooking. Before serving, simply remove the whole onion: no spice pieces to be found on the plate, only a subtle and warm flavor.
It’s a bit like slipping a base note into a perfume: you can’t clearly see it, but it changes everything.
Why does this duo work so well?
This marriage is not a coincidence.
Onions naturally contain aromatic compounds that are gradually released when cooked. It provides a round and slightly sweet base.
Cloves, on the other hand, are rich in eugenol, the molecule responsible for their intense and spicy fragrance. Very concentrated, he could quickly become dominant. Inserted into the onion, it diffuses more gently.
The result: a controlled balance, neither too strong nor too discreet.
A natural air freshener for the home
What is less well known is that this trick goes beyond the culinary context.
In the past, in some country homes, an onion with cloves was placed in the kitchen or pantry to reduce lingering odours.
How does it work?
The onion absorbs some of the ambient odours.
Cloves give off a warm, spicy scent.
Without chemicals or aerosols, the air looks fresher and more pleasant. Of course, this does not replace good ventilation, but for a punctual and natural solution, it is an interesting alternative.
A traditional insect repellent
Another little-known use: the smell of cloves is not appreciated by insects.
Placed near a window or door in summer, this preparation could help limit the presence of flies in the kitchens of yesteryear.
Again, this is not a miracle solution, but a simple, economical method without aggressive substances.
How to make a studded onion at home?
Nothing could be simpler:
- Take a medium onion, preferably peeled if you use it in cooking.
- Gently press 4 to 10 cloves into its surface, spacing them evenly for even diffusion.
- Add it directly to your preparation and let it steep throughout cooking, then remove it before serving.
For home use, place it in a small cup and replace it every one to two days to maintain its effectiveness.
Practical tip: if you use it to flavour a dish, prick the cloves on one side only. This will make it easy to identify the area to be removed.
What to know (and not to believe)
This traditional method has sometimes been surrounded by exaggerated beliefs. Let’s be clear: it does not replace good hygiene, proper ventilation, or medical advice when needed.
Its strength lies in its simplicity, not in extraordinary promises.
Why are these old tricks coming back into fashion?
In the age of sophisticated products and complex solutions, we are rediscovering the charm of simple gestures.
Inexpensive, easy to make, rooted in the right way, this tip embodies a more thoughtful cuisine, more respectful of ingredients and less dependent on the superfluous.
Sometimes the best ideas are not the most modern, but the ones that have stood the test of time without making a sound. A real natural trick from tradition, which reminds us that traditional French cuisine is full of simple and effective solutions.
