What your grandmother did is a classic kitchen trick that’s been used for generations, especially in French and European cooking. Sticking cloves into an onion isn’t just decorative—it actually serves multiple practical purposes.
🌿 Why She Did It
1. Adds Flavor Naturally
- Cloves slowly release warm, aromatic, slightly sweet notes into the dish
- When the onion is simmered in soups, stews, or sauces, the cloves infuse a subtle depth without overpowering the food
2. Makes the Onion Easy to Remove
- Instead of chopping the onion finely, sticking whole cloves into it creates a “bouquet garni” effect
- After cooking, you can easily remove the onion and cloves, leaving the flavor behind but avoiding chunks in the dish
3. Acts as a Mild Preservative
- Cloves have natural antimicrobial properties
- While it won’t make food last forever, it can slightly slow bacterial growth, especially in slow-cooked dishes
4. Aromatic Appeal
- Simmering clove-studded onions fills the kitchen with a comforting aroma
- It’s part of traditional cooking aesthetics—making dishes smell as good as they taste
🥘 How to Use This Trick
- Peel a medium onion and stick 3–5 whole cloves into the surface.
- Add it to your soup, stock, stew, or braise during cooking.
- Once the dish is done, remove the onion with cloves before serving.
