The secret to Laal Maas's distinct flavor lies in the use of a special ingredient called mathania chili. This chili is grown in the Mathania region of Rajasthan and is known for its fiery heat and bright red color. The mathania chili is carefully selected and dried in the sun before being ground into a fine powder. It is then mixed with a blend of other spices such as cumin, coriander, and turmeric to create a flavorful spice mix that is used to marinate the meat for Laal Maans.
