Heat a pan on the gas. After its heated, put the walnuts in it and roast them on a low flame for about 1-2 minutes. Take them out on a plate.
Put the cashews in the same pan and roast them till the fragrant comes and their colour changed to light brown. This will take approximately 2-3 minutes. Take them out on the same plate.
In the same way, roast the almond and take them out on the same plate.
At last roast the pistachios in the pan and keep them with the other roasted dry fruits.
Turn off the flame, put some saffron threads into the same pan, as it is still hot, and roast them. Do not turn on the flame as the saffron threads will get burnt in that situation. Take it out on the same plate.
Keep all the dry fruits aside and let them cool. Once they cool down, put them into a mixer jar and grind them into a fine powder. Do not continuously run the mixer. Give 2-3 seconds break again and again so that the dry fruits do not release their oil.
Store this powder in an air-tight container and keep it in the refrigerator.
