Kaju Katli, also known as Kaju Barfi, is a popular Indian sweet made primarily from cashew nuts (kaju), sugar, and ghee (clarified butter). It is known for its distinctive diamond shape. The sweet is typically thin, smooth, and flat, with a light beige to pale yellow color. It is often garnished with edible silver foil or chopped pistachios, adding to its visual appeal. 
Kaju Katli has a rich and inviting aroma characterized by the natural fragrance of cashew nuts. The scent is sweet, nutty, and slightly floral. The ghee used in the preparation may contribute a subtle buttery note to the overall aroma. The enticing smell of Kaju Katli is part of its charm and adds to the sensory experience.
