1. In a medium bowl, season the meat with turmeric, two teaspoons salt and half a teaspoon of pepper. Set aside.

2. Rinse the beans and place in a medium bowl with one cup water and a generous pinch of salt. Set aside to soak for 30 minutes.

3. In the meantime, place a large Dutch oven or similar pot over medium-high heat. Add three tablespoons oil. When it shimmers, add meat and cook, turning regularly so that it browns evenly on all sides, about 15 minutes. Once the meat has browned, move it to the edges of the pot and add the onion to the centre of the pot, along with a generous pinch of salt. Cook, stirring regularly, until the onion begins to soften and turn brown, eight to 10 minutes.

4. Drain the beans and add to the pot, stirring to combine everything and coat the beans with oil. Add one litre of water, increase heat to high and bring to a boil. Reduce heat to medium-low, cover pot and simmer for two hours.

5. In the meantime, prepare the herbs: Wash parsley and coriander, then use a salad spinner to dry very well. Remove and discard the tough stems. Chop the leaves and tender stems very, very finely, or feel free to use a food processor to get these herbs as finely chopped as possible. The more finely chopped the herbs, the more green and unctuous the ghormeh sabzi will be.

6. Separately chop the chives and entire bunch of spring onions (including the green tops) as finely as possible by hand. These, too, must be very finely chopped — nearly minced — but they will turn to mush in a food processor and thus should be chopped by hand.

7. Set a large frying pan over medium heat. When the pan is hot, add the remaining quarter cup of oil and the spring onion-chive mixture. Allow to wilt, stirring constantly, for about two minutes, then add remaining chopped herbs and fenugreek leaves, crushing the fenugreek leaves between your fingers as you add them. Cook, stirring continuously, until the herbs are wilted and very dark green – but not burned – and they give off a bright green oil when pressed with a spoon, 18 to 20 minutes. This step is crucial to the flavour and colour of the stew. You'll know the herbs are ready when they feel dry and emit a strong, savoury aroma.

8. When the meat has cooked for two hours, add the cooked herb mixture, Omani limes and half a cup of water. Season with salt and bring to a boil. Reduce heat, cover pot, and simmer for another hour. Check on the limes occasionally to make sure they are submerged in the stew but not falling apart. Gently push them into the stew if they're still floating after 20 minutes.

9. As the stew nears the three-hour mark, remove the lid and check the meat; it should be very tender. If the ghormeh sabzi seems a little watery, leave it uncovered for the last 20 minutes of cooking and allow to reduce into a thick stew. Taste and adjust the seasoning with salt and pepper. If the stew needs a little acidity, juice a lime into the stew through a sieve by pressing down on it with a spoon (avoid letting the seeds through the sieve, as they can be bitter). Set aside. Taste the stew and continue adding more lime juice until the stew is sufficiently tangy. Stir in the saffron. The stew should be a very deep, dark shade of green and quite thick when done. Return dried limes into the stew to serve.

10. Serve hot with Persian rice and mast-o khiar.
