1. What is Ha Giang stone cake?

Stone cake, locally called “lua khoai,” is a traditional delicacy of the Dao Ao Dai and Nung ethnic communities in Ha Giang. Made from mountain sticky rice and colored with natural ingredients like butterfly pea flowers and gac fruit, this cake’s uniqueness lies in its preparation and preservation methods, which make it hard when raw but chewy after cooking.

To better understand Ha Giang stone cake, let’s explore its origin, traditional preparation process, and the unique preservation method of this specialty.

1.1 Origin of the Name “Stone Cake”

The name “stone cake” comes from the hardness of the cake in its raw form. With its round, flat or elongated shape, rough surface, and solid texture, the cake reminds people of dry pebbles by a stream. This is why locals call this food “stone cake.”

For generations, this cake has been an integral part of daily meals for the Dao and Nung communities, playing an important role in festivals, weddings, and harvest celebrations. With Ha Giang’s tourism boom, stone cake has gained wider recognition and become a popular souvenir for visitors.

1.2 How is Stone Cake Made?

The main ingredient of Ha Giang stone cake is mountain sticky rice or a mixture of sticky and regular rice, carefully selected for plumpness and aroma. After harvesting, the rice is soaked for 4-6 hours, then dried and ground into fine flour. For vibrant colors, natural ingredients like purple magenta leaves, butterfly pea flowers, turmeric, gac fruit, or pandan leaves are used to create natural dyes that are mixed into the flour.

The flour is steamed until cooked, then quickly pounded while still hot until it reaches the desired elasticity. While the dough is still warm, it’s shaped into cylinders or elongated forms. The shaping must be done decisively and continuously – if hands move too slowly, the cooling dough won’t stick together properly. After shaping, the cakes are left to cool completely and then wrapped in rice straw for three days to dry gradually before moving to the preservation stage.

1.3 The Unique Preservation Method of Stone Cake

After the straw-wrapping period, a natural mold appears on the cake’s surface. At this stage, locals place the cakes under rocky streams near their homes. The cold stream water prevents spoilage and mold growth while maintaining the cake’s elasticity for later preparation. Whenever needed, they simply retrieve the cakes from the stream and steam them again.

Today, for convenient transportation and extended shelf life, many cake producers have switched to vacuum-sealing and careful packaging immediately after production. After purchase, stone cakes should be stored in the refrigerator to maintain moisture, flavor, and prevent mold growth.

2. 5 Delicious Ways to Prepare Ha Giang Stone Cake

In its original form, stone cake has a chewy, fragrant texture with a subtle sweetness. If simply steamed or grilled and eaten plain, it might taste bland and become tiresome. Here are 5 preparation methods to enhance its flavor and create exciting new experiences when enjoying stone cake.

2.1 Stone Cake with Condensed Milk

Cut the stone cake into small pieces, then steam or grill until the outside is crispy golden while the inside remains chewy. When eating, dip directly into condensed milk. The rich creaminess of the milk blends harmoniously with the chewy, fragrant cake, creating a balanced, easy-to-enjoy flavor.

2.2 Fried Stone Cake

After cutting into pieces, deep-fry the stone cake until its surface turns golden and crispy. The crunchy exterior combined with the chewy, fragrant interior creates an unusual and addictive texture. You can dip it in chili sauce for a mild spiciness or enjoy it plain to fully appreciate the rich, nutty flavor of the sticky rice.

2.3 Stone Cake in Sweet Ginger Syrup

“Thang den” is a traditional highland dessert, similar to the sweet glutinous rice balls from the lowlands. When combined with stone cake, this dish becomes uniquely exotic with distinct mountain flavors. The cake is sliced into strips or small pieces, boiled until soft, then served with ginger-infused syrup. Sprinkle with roasted peanuts to add crunchiness and nutty flavor. The chewy texture combined with sweet and mildly spicy flavors creates an unforgettable taste.

2.4 Stone Cake Noodle Soup

Instead of using regular noodles, you can cut stone cake into strips and use them as the main ingredient in noodle soup. When cooked, stone cake maintains its chewiness and fragrant, nutty flavor thanks to the mountain sticky rice. The cake absorbs the broth flavors and, when eaten with meat, sausage, or shrimp, offers a fresh experience of a familiar dish.

2.5 Stone Cake Tteokbokki

With its chewy texture and distinctive mild nutty flavor, stone cake can perfectly substitute for Korean tteokbokki. Simply cut the cake into bite-sized pieces, then cook with a sweet and spicy sauce made from Korean chili paste (gochujang), leeks, and fish cake. The stone cake will absorb the sauce evenly, maintaining its chewiness without becoming mushy, creating a “Vietnamese tteokbokki” that’s both unique and easy to prepare at home.
