Prehea oven at 350F.
Add saffron(kesar)to the warm milk. Keep aside.
Mix kaju powder, powdered sugar, cardamom powder in a medium bowl.
Prepare semi soft dough with the help of saffron milk. Add tbsp at a time till you get nice dough consistancy
Prepare about 10 small balls of 1 tbsp or 20-25 gms each.
Flatten each ball with hand or roll each ball about 2" diameter, thickness of puri should be about 1/4 inch only.
If you wish, you can make these puris with different shapes and make some design even on top.
Repeat with the remaining balls.
(Or you can roll other way, take dough and make big ball and roll 1/4 inch thick and then take round cookie cutter to cut. This way, you will get all even and same size puris.)
or for fancy edge, use cookie cutter like below. Even different shapes such as heart or star can be used:
Now, cover baking tray with foil. Place puris on baking tray.
Bake about 12-15 minutes or till it changes color slighly to nice golden.
Remove and let it cool down.
Do not use cashews right from referigerator. I keep my nuts in fridge so when I want to make this puri, I take out cashews day before from refrigerator and keep at room temperature. This will help to make powder good.
If you don't have oven, bake them on tava on very low flame.
