Peel and cut the melon into small pieces. (Note: Dưa gang is a type of melon similar to honeydew or cantaloupe.)

In a small saucepan, mix the mung bean powder with 1/3 cup water (about 100 ml) and cook over low heat, stirring, until thickened. Place the melon pieces in a blender. Add the heavy cream or milk and sugar.

Add the cooked mung bean mixture and sweetened condensed milk to the blender. Blend until smooth. Add the crushed ice and blend again until everything is well combined.

For extra flavor, top with a little whipped cream before serving cold.
