Sweet Memories of Hue: Discovering Cau Candy

On the land of the Perfume River and Ngu Mountain, beauty is not only found in the poetic scenery but also in the humble flavors that carry deep cultural meaning. Among these is keo cau, a traditional candy that has endured through generations in Hue. Though small and simple, this sweet treat holds an entire world of memories and craftsmanship.

A Labor of Love

Despite its name, keo cau is not made from areca nuts. Instead, it takes its form from betel nut slices, with a golden core resembling the fruit’s interior wrapped in a milky-white outer layer. Centuries ago, some versions even included real areca nut, but the strong flavor led artisans to refine the recipe into the form we know today.

The process of making keo cau is painstaking. Sugar, water, and malt are boiled and stirred until just the right consistency is reached, then infused with ginger and caramelized sugar for color. Timing is crucial, too little heat and the candy melts, too much and it crumbles. Once removed from the fire, the hot mixture is quickly pulled, stretched, and divided into layers: a golden core and a pliable outer shell. Roasted peanuts are sometimes added to enrich the taste before the candy is rolled, cut, and dusted with flour. Finally, the bars are split into quarters, each crack releasing a sharp, cheerful sound that echoes through Hue’s kitchens.

A Distinct Way to Savor

Keo cau is famously hard, so rather than chewing, locals let it dissolve slowly on the tongue. The sweetness of sugar blends with the warm spiciness of ginger, creating a layered flavor best enjoyed with tea. This unhurried way of eating mirrors Hue’s contemplative lifestyle, turning each bite into a cultural experience.

A Taste of Childhood

For generations, keo cau has been more than just candy, it is a keepsake of Hue’s childhood. Children once waited eagerly for parents to return from the market, hoping to find these small, crystalline sweets tucked away in their baskets. Even as modern snacks dominate shelves, keo cau remains deeply rooted in the memory of Hue natives, a reminder of family, tradition, and tender love.

Though few households continue the craft today, a handful of dedicated artisans still keep the fires burning, their hands pulling sugar with care and devotion. Keo cau endures not only as a sweet treat but also as a symbol of Hue’s enduring cultural heritage.
