Instructions

1. 1

   Bloom the saffron: place crushed saffron in a small cup, pour over 60 ml boiling water, cover, and steep 15 minutes. Keep warm. Meanwhile, set yogurt out to reach room temperature; cold yogurt is more likely to split when added to the stew.

2. 2

   Prepare a stabilized yogurt base: whisk yogurt, egg yolk, and flour until perfectly smooth, 1–2 minutes. Whisk in 2 tbsp (about 30 ml) of the saffron infusion and reserve the rest for finishing. Keep the bowl at room temperature while you cook the meat.

3. 3

   Brown the beef: heat a heavy pot over medium-high for 2 minutes. Add oil and 30 g butter. When foaming subsides, add beef in a single layer (work in batches if needed) and sear 6–8 minutes total, turning to brown multiple sides. Transfer browned beef to a plate.

4. 4

   Build the aromatic base: reduce heat to medium. Add onions to the same pot and cook 10–12 minutes, stirring often, until deeply golden. Add garlic and cook 45 seconds. Stir in turmeric, cinnamon, and cardamom for 30 seconds to bloom the spices without scorching.

5. 5

   Braise the beef: return beef and any juices to the pot. Add salt, pepper, and 900 ml hot water. Bring to a gentle boil, then reduce to a low simmer, cover, and cook 75–90 minutes, stirring occasionally, until the beef is tender and the liquid is reduced to a light stew consistency.

6. 6

   Toast the almonds: in a small skillet over medium heat, melt the remaining 30 g butter. Add almonds and stir constantly 3–5 minutes until lightly golden and fragrant. Immediately scrape almonds and butter into a bowl to stop browning; set aside for the final simmer.

7. 7

   Temper and add the yogurt: reduce stew heat to very low (no bubbling). Ladle 120 ml of hot stew liquid into the yogurt mixture while whisking continuously, then whisk in another 120 ml. Pour the warmed yogurt mixture into the pot, stirring gently until the stew turns creamy and uniform.

8. 8

   Finish with balance and aroma: keep heat very low and cook 10–12 minutes, stirring frequently, ensuring the stew never boils. Stir in grape vinegar, sugar (if using), toasted almonds with butter, and the remaining saffron infusion. Taste and adjust salt, pepper, and vinegar, then rest 10 minutes off heat.
