Top 9 tips for boiling delicious Tet sticky rice cakes with a natural green color

How to arrange the cakes is also crucial to the quality of the Banh Chung. Before arranging the cakes in the pot, use leftover leaves and stems to line the bottom to prevent the cakes from burning, while helping them retain their natural green color.

When placing the cakes in the pot, avoid arranging them too loosely or too tightly. If the cakes are placed too loosely, they will separate and cook unevenly. If they are packed too tightly, the cakes may burst as they expand during cooking. Arrange them in a moderate and organized manner, layering them properly.

Before boiling, don't forget to line the bottom of the pot with string or whole dong leaves to prevent burning and make the water greener. Always keep the pot boiling and never let it run low on water, so be sure to prepare extra water nearby. Remember, never add cold water to a pot of boiling Banh Chung, as this will cause the cakes to burn and cook unevenly.

Cooking the cakes to perfection is not an easy task. To ensure a delicious cake, it's best to cook them with firewood, which will speed up the cooking process and ensure the cakes cook evenly and taste better. During the cooking process, maintain a steady flame and never let the water level drop too low. About halfway through the cooking time, if you want the cakes to be even greener and tastier, take the cakes out, change the water, rinse the cakes with cold water, and continue boiling. This will help the cakes cook faster, more evenly, and result in bright green leaves. The ideal cooking time is around 10 to 12 hours for perfectly cooked, delicious Banh Chung.

The process of selecting the right ingredients is crucial as it greatly influences the quality and appearance of the Banh Chung. To make a delicious Banh Chung, you must start with high-quality ingredients:

• Choosing Rice: The sticky rice used for wrapping Banh Chung should be from the season or the special variety known as "Cai Hoa Vang", with plump, shiny grains. Soak the rice in cold water for about 10-12 hours, then rinse and drain. After that, sprinkle a moderate amount of salt to enhance the flavor. The distinctiveness of Banh Chung lies in the saltiness of the rice, the fragrance of mung beans, and the savory richness of the pork. If you want the rice to have a more vibrant color and a stronger aroma, you can soak the rice in pandan leaf extract, which gives the rice a beautiful green hue when wrapped.

• Choosing Mung Beans: The mung beans are the filling close to the center of the Banh Chung. You can buy pre-peeled beans or unpeeled ones. If you choose unpeeled beans, you’ll need to soak them to remove the skin. Though this takes more time, using unpeeled beans ensures a fresher, tastier, and more hygienic result. The golden color of the mung beans symbolizes prosperity for the new year. Always choose beans that are uniform in size and free from any mold or pests.

• Choosing Pork and Spices: No Banh Chung is complete without pork and shallots. Peel and chop the shallots, and use freshly ground pepper or buy it from the market. The pork used should be a mix of lean meat and fat, typically belly pork. The fat gives the cake a rich, indulgent flavor, while the lean meat represents joy and happiness for the new year. Cut the pork into uniform pieces, season with the right amount of spices, and sprinkle a bit of pepper for a subtle heat and fragrance. The best pork for Banh Chung is a balanced mix of lean and fat to ensure the cake is delicious and flavorful.

• Choosing Dong Leaves: The key to perfectly cooked Banh Chung is choosing the right leaves. Opt for leaves that are not too large or too small, with a glossy surface, deep green color, and small stems. Avoid leaves that are too young or too old. After cleaning the leaves, dry them in a cool, well-ventilated area—don’t expose them to direct sunlight, as this can cause them to wilt. Depending on the weather, use 6 leaves if it’s cool, or up to 10 leaves if it’s hot, to ensure proper preservation of the cake after cooking. The leaves you select should be neither too old nor too young, as this will impact the color of the cake. Choose leaves that are glossy and firm for the best wrapping results.

To soak the rice, you can use ginger leaves or herb leaves like Bo Ngot (water spinach) by crushing or grinding them to extract the juice, which is then mixed with the rice just before wrapping. This method will give the rice a lovely green color and a pleasant aroma. Alternatively, you can soak the rice in pineapple water for 1-3 hours, but be careful not to soak it too long, as the rice may turn into mush. Another popular method is to soak the rice in lye water, a technique commonly used in Central Vietnam. The alkaline properties of the lye water help make the rice clearer and give it a beautiful green color when cooked, while still preserving the delicious flavor of the Banh Chung.

To ensure the rice cooks evenly and remains green, it’s important to wash it thoroughly multiple times until the water runs clear. The cleaner the rice, the clearer the wrap will be, and the longer it will stay fresh without spoiling.

When mixing ingredients, for instance, sticky rice, be sure to mix it with salt so that the finished Banh Chung will have a rich, savory flavor. For the filling, combine pork with mung beans, shallots, pepper, and a pinch of seasoning. Be careful not to add too much seasoning, as this could cause the cake to spoil faster. Less is more to maintain freshness and flavor over time.

Before wrapping the cake, grind or crush ginger leaves and mix them with the rice. This will give the cake a vibrant green color both inside and out, along with a fragrant aroma that adds a unique touch and makes it taste even better.
