Iruttu Kadai Halwa is a traditional Indian sweet originating from Tirunelveli, a city in the southern state of Tamil Nadu. This dessert is made primarily from wheat flour, sugar, ghee, and milk, resulting in a rich, dense texture. It is known for its unique preparation method, which involves slow cooking to achieve the perfect consistency and flavor. The halwa is typically served warm and is often enjoyed during festivals and special occasions. Its popularity has led to various adaptations, but the original recipe from Iruttu Kadai, a famous shop in Tirunelveli, remains highly sought after for its authentic taste and quality.
