2teaspoongingerfinely minced

1sprig curry leaves
½ to ¾teaspoonturmeric powder
Salt to taste
500mlbuttermilkfull-fat, room temperature (see notes)
Instructions
Bring the buttermilk to room temperature before starting. If using bottled laban, shake well. If using thick curd, whisk 1 cup curd with 1 cup water until smooth. Prep all ingredients before heating the pan: mince the ginger, chop the chillies, dice onions.
Using curd and water gives a slightly thicker curry than laban. Prefer it thicker? Go with curd and water. Prefer it thinner? Use laban or add a splash more water to the curd mixture.
Heat the coconut oil in a small deep saucepot on low to medium heat. Add mustard seeds, let them splutter. Then add fenugreek seeds, dried red chillies, and a few curry leaves. Fry for a few seconds.
Add onions and sauté until soft, translucent, and lightly golden at the edges.
1 small onion
Add ginger, green chillies and salt; sauté for a minute. Reduce the heat to low. Add turmeric powder; stir for a few seconds.
2 teaspoon ginger, 3 to 5 green chillies, ½ to ¾ teaspoon turmeric powder, Salt to taste
Turn off the heat. Pour in the room-temperature buttermilk and stir well. Season with more salt, if necessary.
500 ml buttermilk
Turn the heat back on to the lowest setting. Stir continuously until the curry is warmed through and uniformly yellow. The moment you see light steam, switch off immediately. Do not boil.
Serve immediately with hot steamed rice, any south-Indian beef or chicken sides and veg stir-fries.
Notes
Nutrition values are estimates and will vary based on the brand of laban or curd used.
Buttermilk options: Bottled laban works perfectly and is the easiest option. Alternatively, whisk 1 cup of thick sour curd with 1 cup of water until completely smooth. The sourer the curd, the more flavourful the curry. Room temperature is non-negotiable.
Salt early: Adding salt when sautéing the onions helps them soften faster and seasons the base evenly before the buttermilk goes in.
Never boil: This is the single most important rule. The moment you see steam rising, turn off the heat.
Make it spicier: Increase the green chillies or dried red chillies up to 6–7 for a fierier moru curry.
Leftovers: Refrigerate and consume within 1 day. Reheat very gently on the lowest heat, stirring continuously, and stop well before it boils.
