The Taste of Tet

It wouldn't be the New Year without kho, the ultimate Vietnamese comfort food.

For many people, Vietnamese cuisine means a big bowl of pho and a couple of spring rolls, those delicious and ubiquitous standards of noodle shops and takeout joints. But for folks like me--raised and fed by Vietnamese parents--the salty-sweet flavors of a mahogany-colored kho dish best capture the Vietnamese food experience.

And as the Tet lunar New Year celebration approaches--it begins Tuesday--I've got kho on my mind.

Kho dishes occupy a central spot in the Vietnamese culinary consciousness. In fact, it's hard to be Viet without serving and/or eating kho at your table. Growing up in San Clemente, my cultural heritage was reinforced at dinnertime. While my friends dove into tuna casseroles, I spooned my mother's heady kho into bowls of white rice.

For traditionalists like my parents, who spent most of their lives in Vietnam, kho remains an integral part of their daily routine. Whenever I go to their house, there's a kho cooking on the stove or sitting in the fridge, just waiting to be served.

What exactly is kho? As a noun, kho means a type of dish that is the ultimate in Vietnamese comfort food--a stew in which the delicate sweetness of a light caramel offsets the vibrant saltiness of fish sauce.

Aside from being a whole category of food, kho is also a verb that means to simmer, braise or stew something. In the main, when someone says, "I'm kho-ing something," you can bet that they're cooking up home-style food in a caramel-based sauce.

Originally, kho (pronounced "kaw") dishes were made by simmering meat, seafood or tofu with fish sauce, sugar and water in clay pots. Most modern Vietnamese cooks use metal saucepans and employ nuoc mau ("nook mao"), a caramel sauce that deepens the overall color and flavor. Literally it means "colored water." In the north, people call the same ingredient nuoc hang ("nook hahng"), literally "merchandising water," probably because it was so often used by food hawkers to enhance the appearance of their wares.

A typical Vietnamese meal consists of rice, kho, a stir-fry and soup. "You can leave out the stir-fry and the soup, but you can't forget the kho," my dad says. "There's always plenty of rice, and you have to eat it with something salty."

To prepare a basic kho dish, you simply place all the ingredients in a saucepan and let them cook until the meat juices have exuded and combined well with the other elements, and the overall color is as reddish-brown as dark honey. Creative cooks can doll things up by grilling or briefly sauteing the meat or fish before simmering it with the caramel sauce and other ingredients. If it isn't naturally present, a little fat or oil is added for richness.

Though the color darkens slightly overnight, kho dishes reheat beautifully, so Vietnamese cooks often prepare large quantities with leftovers in mind.

Kho dishes originated before refrigeration was available in Vietnam and cooks needed to preserve food to accompany the mainstay of their diet, rice. To that end, they infused food with the saltiness of fish sauce, their beloved condiment. But things cooked in pure fish sauce were overly salty, so sugar was added to balance the flavor.

Still, the color wasn't quite right, so they started experimenting and eventually adopted the practice of caramelizing the sugar into an inky, bittersweet sauce (think black coffee or molasses). Diluted during cooking, the dark red cast of this caramel sauce imparts a beautiful color. The use of nuoc mau negated the need to add sugar to the sauce, though some cooks still do. The caramel's bittersweet edge also helps counter the saltiness of the fish sauce and brings out the savory aspects of whatever is being cooked.

A kho made with a caramel-based sauce is rich in flavor and lush in texture. Because kho is such an important part of a Vietnamese cook's repertoire, nuoc mau is a staple in the Vietnamese kitchen, where it's made in large batches and stored in a jar, usually kept in the cupboard. Just spoon some into a saucepan with all the other ingredients and you're ready to go. Some cooks add ginger, hot chile peppers, galangal or whole peppercorns for extra pizazz.

As with any dish that is so simple, the quality of the ingredients is important. Fish sauce, in particular, varies depending on the manufacturer and country of origin. Tiparos brand, which is widely available, is produced in the Thai style, which means that it's heavier and saltier. Vietnamese-style fish sauce (Viet Huong/3 Crabs is my favorite brand--it's made in Thailand but to the Vietnamese taste) is lighter and a bit sweet because some fructose is usually added.

Traditional Vietnamese cooks such as my mother keep a Tiparos-type of fish sauce around for cooking (it's cheaper) and use the more delicate Vietnamese-style fish sauce ("more expensive" at about $2.49 a bottle) to make their dipping sauces.
