Red Ruby is a popular traditional Thai dessert at Nong Khai Beer House. It features fresh water chestnuts, cut into small pieces, coated in flour to create a crunchy, chewy texture. The water chestnuts are then submerged in a sweet, fragrant syrup and topped with smooth, rich coconut milk. The dessert is served with crushed ice, offering a refreshing, cool sensation in every bite. The dish has a well-balanced sweetness and creaminess, making it the perfect way to end a flavorful Isaan meal.
