Biryani Masala is a blend of spice mix that is used to prepare aromatic biryani.
Always store in a dry clean airtight container to increase its shelf life. Do not leave it open the aroma will easily get lost.
Roasting are done to bring out the aroma of the spices and to prevent the masala powder from getting spoil.
