Step 1
- a.Prepare the Vegetables (15 mins)
- b.Thoroughly wash the fiddlehead ferns (dhekia) under running water to remove any dirt. Trim any tough ends and roughly chop them into 1-inch pieces.
- c.Peel the taro root (kosu) and cut it into small, uniform 1/2-inch cubes. To prevent itchiness, you can soak the cubes in salted water for 10-15 minutes and then rinse.
- d.Finely chop the garlic cloves and slit the green chilies lengthwise.

Step 2
- a.Temper the Spices (2 mins)
- b.Heat the mustard oil in a kadai or heavy-bottomed pan over medium-high heat until it just begins to smoke lightly. This reduces its pungency.
- c.Lower the heat to medium, add the panch phoron, and allow the seeds to crackle and become fragrant, which takes about 30 seconds.
- d.Add the chopped garlic and slit green chilies. Sauté for another 30-45 seconds until the raw smell of garlic disappears.

- c.Stir-fry for 2-3 minutes, ensuring the taro cubes are well-coated with the oil and spices.
- d.Pour in 1/4 cup of water, stir, and bring to a simmer. Cover the pan, reduce the heat to low-medium, and cook for 8-10 minutes. The taro should be about 80% cooked and tender when pierced with a fork.

Step 4
- a.Add Fiddlehead Ferns and Finish (8 mins)
- b.Add the chopped fiddlehead ferns to the pan. Mix everything gently but thoroughly.
- c.Cover and cook for 5-7 minutes, stirring occasionally. The ferns will release some water and cook down.

What to keep in mind.
4 tips from the recipe — small details that make a real difference to the final dish.
- 1For the most authentic flavor, use mustard oil and do not substitute it. Heating it properly before adding spices is key.
- 2Fiddlehead ferns cook quickly. Add them only after the taro root is almost cooked to maintain their crisp-tender texture.
- 3If you experience itching while handling taro root, you can apply a little mustard oil to your hands before peeling and chopping.
- 4Panch phoron is a blend of five whole spices: fenugreek, nigella, cumin, black mustard, and fennel seeds. It's crucial for the dish's aroma.
