Knol khol recipe is a Kashmiri-style kohlrabi curry where pan-fried knol khol is cooked in a yogurt-based gravy with fennel, asafoetida, kashmiri chilli powder and dry ginger powder. It uses whole spices and does not include onion or garlic. The gravy is flavorful, a bit spicy and pairs well with rice or flatbreads.
Prepare a mixture of Kashmiri chili powder and asafoetida with 1 tablespoon water. Set this chilli water mixture aside.
Heat mustard oil and pan fry chopped knol khol until golden and tender. Remove and keep aside.
Some mustard oil will remain in the pan. Use the same oil and heat it on low. If it looks less, add about ½ tablespoon more if needed.Alternatively, you can use 1 to 2 tablespoons fresh mustard oil.
When the oil is moderately hot, add black cardamom, cloves, black peppercorns and shahi jeera.
Add the prepared chili and asafoetida water mixture. Mix well and cook for about half a minute on low heat.
Switch off the heat and add in whisked yogurt, dry ginger powder and fennel powder. Mix thoroughly.
Add 1 cup water and salt according to taste. Mix well.
Add pan fried knol khol to the pan.
Cover and simmer for 15 to 20 minutes on low to medium-low heat until the gravy thickens slightly and coats the kohlrabi pieces.
Notes
Add yogurt only after turning off the heat or reducing the heat to its lowest.
Do not burn the chili water mixture.
Pan fry knol khol well before adding to the gravy.
Adjust the consistency of the curry as needed, but do not make it very thin.
