Coimbatore street food Mushroom fry (kaalaan varuval)

Kaalaan varuval (mushroom fry) or chilli mushroom is a very famous street food of Coimbatore, which you can find near busy market places or children’s parks where the street vendors sell this delicious street food. Though I am not a very big fan of mushroom, for a change I sometimes prepare mushroom curry, mushroom 65 and mushroom pokada. After tasting this mushroom fry (kaalaan varuval) street food, it was a hit for me. It was so delicious that I can eat it regularly. When I saw the street vendor preparing the kaalaan varuval (mushroom fry), it looked like a very long process. To prepare kaalaan varuval, you need stock, fried mushroom and then a curry, which the vendor prepares in advance so that he can serve the customers quickly and hot.

To prepare this delicious street food, kaalaan varuval (mushroom fry), I have used my home made biryani masala, for both the marinate and sauce (curry). I made the cooking process easy for home cooking and not too complicated like the method followed by the vendors. The end result of kaalaan varuval is so delicious and yum, with full of aroma and flavour. As soon as you taste the mushroom fry (kaalaan varuval) it will become one of your favourite dishes.

  • My home made Biryani masala is a must as it has special spices like dagad phool, star anise. You can prepare in advance and store in airtight container. You can use for the pulaos and biryanis.
