Boil suran slices in hot water (with some salt) in a pot for about 5 mins or so until it gets slightly softer and then drain the water.  You can avoid boiling the suran and instead cook them directly but I have found that if you boil and drain the water, the itchiness that is generally present in suran is gone/ or gets reduced to a greater extent.

Add sambar powder (or sambar powder substitute), turmeric powder, fennel powder and salt to the boiled suran slices and toss/ mix well.

Slow roast the suran slices in a pan for about 5 to 10 mins by adding liberal amount of oil in the beginning and towards the middle of the frying process.

Turn the pieces so that both sides get evenly roasted to golden brown color.

Enjoy with your favorite dish or as a snack!
