Unlike North Indian dishes, which frequently contain onion, ginger, garlic, and garam masala, South Indian food frequently utilizes roasted lentils, mustard seeds, and dried red chilis to provide a light yet distinctive flavor. The mustard seeds are popped in hot oil to release their characteristic flavor, and the lentils are then added to impart the oil with a nutty flavor. Red chilis provide a bit of heat, and asafetida provides an earthy flavor that is reminiscent of but not quite as pungent as leeks or shallots.

*****
South Indian Spiced Purple Cabbage
(serves 4)
1 medium head of purple cabbage (about 3 lbs)
2 teaspoons canola oil
1 ½ teaspoons black mustard seeds
2 teaspoons urad dal
½ - ¾ teaspoon red chili flakes
2 pinches of asafetida powder
¾ teaspoon salt, plus more to taste
6 curry leaves, torn into small pieces
***************
Cut the cabbage in half and remove the core, then slice into thin strips about 1/8” thick. [This will fill a large bowl, but cabbage cooks down a lot, so you’ll end up with only about 1/3 the original volume.]
Put the oil into a large pot with a lid set over medium-high heat. When the oil is hot, add the mustard seeds and cover the pot. The seeds will start to pop; after about 10 seconds of popping, lower the heat to medium, add the urad dal, chili flakes, and 1 pinch of asafetida, and cover the pot. When the urad dal is golden brown – this will take less than 30 seconds – add the cabbage, remaining asafetida, salt, and curry leaves and stir very well. Cover the pot and and reduce the heat to medium-low.
Cook covered, stirring occasionally, until the cabbage is tender but not mushy, about 12-14 minutes. Add more salt if necessary.
Serve warm with basmati or jasmine rice and plain yogurt.
