Ms. Duong Thuy Dung puts black jelly cake with green bean filling into a box.

In the hot sun of early May 2025, we had the opportunity to visit Dung Bo black jelly production facility, Ban Moi area, That Khe town. While busily preparing ingredients to make black jelly cakes with green bean filling, Ms. Duong Thuy Dung, the owner of the facility, said: My family has been making black jelly for sale for about 8 years now. In early 2024, realizing that customer demand was increasing, my family tried making black jelly cakes with green bean filling and received support from many customers. On average, my family makes 1,000 - 2,000 boxes of black jelly cakes with green bean filling each month, with a selling price of 40,000 VND/box (10 pieces). The main consumption market is in the province and some other provinces and cities such as: Hanoi , Bac Giang, Bac Ninh ...

Like black jelly, black jelly cake is made from handmade, easy-to-find ingredients. The cake crust is made from black jelly, and the filling is made from green beans and sugar. To make black jelly cake with green bean filling that is crispy, delicious, and has a beautiful color, the choice of ingredients is very important. Accordingly, people often use the jelly plant to cook the jelly. After drying the jelly, wash it, put it in a pot and simmer it with water for 4-6 hours, then take it out and filter it many times, then mix the tapioca starch into the jelly juice and cook it on the stove for about 2 hours.

For the green bean filling, the maker must choose delicious green beans with plump, golden beans. After soaking in water for 3 to 4 hours, the green beans are steamed until soft, then pureed and mixed with sugar, then kneaded until the filling is soft and divided into small portions to make the filling. Depending on each person's taste, the maker can reduce the amount of sugar to make the filling sweeter to suit.

According to the makers of black jelly cakes with green bean filling in That Khe town, the cakes look simple but the makers have to go through many stages and require dexterity and meticulousness. In particular, the step of pouring jelly and filling must be done quickly, the maker pours the jelly into a small plastic cup, then skillfully puts the filling in the middle of the jelly so that the filling layer fits neatly in the jelly shell. If not done quickly, the jelly will solidify, and when adding the filling, it will not stick together.

The finished black jelly cakes with green bean filling are round in shape, after cooling they will be packaged in boxes, the selling price ranges from 35,000 - 40,000 VND/box. Unlike traditional black jelly, which can be stored in the refrigerator for up to a week, black jelly cakes with green bean filling can only be kept for 2 - 3 days because the green bean filling has a shorter storage time, if not refrigerated it will easily spoil, therefore, households that make black jelly cakes with green bean filling often make cakes and sell them on the same day.

Ms. Tran Thi Phuong, Quan Hoa Ward, Cau Giay District, Hanoi City said: Through the social network Facebook, I learned about the black jelly cake with green bean filling of Trang Dinh District and ordered some to try. I found the cake very unique when eating, the cake is chewy, crispy, fragrant, has the rich and fatty taste of green beans but is still very refreshing, so my whole family loves it. That's why I often order this cake to eat and give as gifts to relatives.

Mr. Nguyen Duc Tho, Vice Chairman of That Khe Town People's Committee, said: Trang Dinh black jelly is a favorite dish of many people. Currently, in addition to making traditional black jelly, there are 3 households in the town making black jelly cakes with green bean filling to supply to the market in and outside the province. In the coming time, to spread and develop the product, in addition to promoting households to do a good job of ensuring food hygiene and safety, the town government will coordinate with related units to create conditions for bringing products to display at conferences and events in and outside the district to promote the product; at the same time, promoting and orienting households to build OCOP products (one commune one product program), the town People's Committee will support and guide establishments to prepare documents and registration procedures to strive to build, thereby contributing to increasing the diversity of products made from black jelly on the market.

Not only is it a new dessert, black jelly cake with green bean filling is also a food with many health benefits. This cake can be enjoyed immediately after making, but it will be more delicious if kept in the refrigerator for 1-2 hours before eating. With the refreshing taste of black jelly, the sweet taste of green beans, all blend together to create a unique, delicious flavor that is not greasy, loved by many customers in and outside the province. If you have the opportunity to come to Trang Dinh district, do not forget to enjoy this unique cake to feel this very special flavor.
