A Journey Through Time: The History of the Yellow Onion

The yellow onion (Allium cepa) boasts a rich and ancient history, its origins traced back thousands of years to Central Asia, specifically in regions like modern-day Iran and Pakistan.

Ancient civilizations recognized the onion’s significance. Egyptians revered it, incorporating it into religious rituals, burial practices, and even using it as a form of currency.

Mastering the Kitchen: Cooking Techniques for Yellow Onions

The yellow onion is incredibly versatile in the kitchen, adapting beautifully to various cooking methods. From the subtle sweetness of slow-cooked caramelised onions to the smoky char of a grilled onion, the possibilities are endless.

• How to Prepare a Yellow Onion: Preparation is key!
