Instructions

1. 1

   Bring a large pot of water to a rolling boil, then add 2 tsp salt from your measured salt. Add the cabbage and blanch for 3 minutes to soften and tame sharpness. Drain well and spread on a tray for 5 minutes so excess water evaporates; this prevents a watery stew.

2. 2

   In a heavy pot or Dutch oven, heat the oil and butter over medium heat for 2 minutes. Add the onion and cook 8–10 minutes, stirring, until translucent and lightly golden. Add garlic, turmeric, ginger powder, and black pepper; cook 45 seconds until fragrant, keeping heat moderate to avoid burning.

3. 3

   Add the carrot and potato. Stir to coat in the aromatics, then cook for 4 minutes. Pour in the vegetable stock, bring to a gentle boil, then reduce to a steady simmer. Cover and cook 15 minutes, stirring once halfway, until the potatoes are about 70% tender (a knife meets slight resistance).

4. 4

   Stir in the blanched cabbage, cover again, and simmer 10 minutes. Add the spinach in two additions, stirring each time until wilted, about 2 minutes total. Keep the heat at a gentle simmer; vigorous boiling can dull the greens and make the yogurt sauce more likely to split later.

5. 5

   Make the creamy base: in a bowl, whisk the flour with 120 ml of hot broth ladled from the pot until completely smooth. Whisk in the room-temperature yogurt and mustard sauce until glossy. This tempering step stabilizes the yogurt and prevents curdling when it hits the hot stew.

6. 6

   Lower the pot to low heat so the stew is steaming but not bubbling. Slowly pour in the yogurt mixture while stirring constantly for 1 minute. Add the grated cheese and stir 2–3 minutes until melted and velvety. Simmer very gently, uncovered, for 8 minutes, stirring often, to thicken.

7. 7

   Taste and adjust salt with the remaining measured salt if needed. Stir in lemon juice and cook 1 minute more. Turn off the heat, cover, and rest 10 minutes so the flavors settle and the sauce finishes thickening. Serve hot with rice or bread, spooning extra sauce over each portion.
