Start by boiling the arbi. Add the cleaned arbi to a large pot of water and cover. Let boil for 10-12 minutes on high. You have to boil them just until fully cooked(easily fork tender) but not mushy. To avoid overcooking, I prefer to boil them in a pot of water instead of pressure cooker or Instant Pot. Note - Boil for 2 whistles in pressure cooker and pressure cook on high for 2-3 minutes using IP.
Once boiled, let arbi cool down for few minutes. Peel the skin off. Using a sharp knife, half each arbi. Let sit to cool down completelyNote - You can do the above steps a day ahead. Keep boiled arbi refrigerated.
In a heavy cast iron skillet or kadai(indian wok) , heat up the mustard oil until the raw smell goes away.
Temper with ajwain & cumin seeds, hing powder and chopped green chillies. Fry for 30 seconds or so on low flame taking care not to burn.
Add the powdered spices(except chaat masala), salt and a splash of water. Fry the spices for 20-40 seconds. You will see a slurry.
Add the arbi halves and gently toss to coat with spices. Continue to fry for next 4-5 minutes without stirring a lot else arbi will start breaking. Let char slight on each side and gently flip on to the other.
Finish arbi fry with chaat masala, pinch of garam masala , lemon juice and lots of chopped cilantro. Your arbi fry is ready to serve.
Notes
Choose fresh and firm arbi- Fresh arbi has a crunchy taste that will enhance the taste of the dish after cooking. Make sure that the arbi is firm to touch and has no bruises.
Oil your handsor wear gloves- I recommend rubbing smearing your hands with some oil when touching arbi. Wear gloves if necessary or wash your hands thoroughly after handling. This prevents itchiness of skin.
Dont skimp on oil - Arbi is one of those vegetables that need extra oil for better taste.
Choose a wide pan or kadai- Else instead of charring(frying), the arbi will start steaming and get too soft spoiling the texture of the dish.
Always use a sour agent- Like lemon or lime juice, amchoor or a little yogurt when making arbi.
Skip hing powder for a gluten free arbi fry.
Serving Suggestions
One of my favorite ways to eat arbi fry is with indian flatbreads like warm rotis or plain paratha and green chutney. You could add a bowl of yogurt on the side.
For a delicious summer meal, serve arbi fry with steamed rice and mango dal.
