Dry roast all the spices except Asafoetida and Dry Mango powder separately for around 1-2 minutes till aroma come from the spices. Spices can be roast all together but I prefer to roast them separately since they may require different time for roasting.
Let the spices cooled completely.
Now coarsely grind spices using a mixer or Shil-Nora or Silbatta. We don’t need superfine spice powder for Achari Masala.
Now mix Dry Mango Powder and Asafoetida to the spice mixture.
Achari Masala is ready and can be stored in an Airtight Container for around 2 months.
