Kwecang with kaya sauce is a sweet dish where a glutinous rice dumpling (kwecang) is served with a sweet, rich kaya sauce. Kwecang is essentially a sweet version of the savory bakcang, and it's typically made with glutinous rice and water ash, giving it a chewy texture. Kaya sauce, often made with coconut milk and eggs, is a popular condiment in Southeast Asian cuisine, known for its creamy, slightly sweet flavor.
