Ghormeh Sabzi

Ghormeh sabzi is a dark green herb stew of parsley, coriander and fenugreek simmered for hours with kidney beans, dried lime and lamb. Ask nearly any Iranian to name the country's single most beloved dish, and this stew, not any of the more famous rice dishes or kebabs, is what comes up most often.

What it really is

A large volume of fresh herbs — parsley and coriander form the base, with fenugreek leaves adding a distinctive, slightly bitter depth — sautés down slowly in oil until it darkens and reduces significantly, concentrating its flavour well beyond what the raw herbs alone would suggest. Lamb browns separately and joins the herbs along with kidney beans and whole dried limes, which have been soaked and pierced to release their sour, fermented-citrus flavour throughout the stew. The whole pot simmers for hours, long enough for the lamb to turn tender and the herbs to meld fully into a thick, deep green sauce.

The herb sauté is what separates a good ghormeh sabzi from a mediocre one, more than any other step. Rushing that initial cook, when the fresh herbs reduce and darken in the oil, leaves the finished stew tasting grassy and thin rather than deep and concentrated — the time spent there is where most of the dish's character actually comes from.

How it's served

• Hot, ladled generously over steamed basmati rice.
• With extra dried lime or a wedge of fresh lime on the side.
• As a main course, a genuine everyday staple across Iranian households.

How to write it on the menu

• No major allergens are inherent to the base recipe.
• Say what herbs are used, since fenugreek in particular is essential and not always familiar to guests.
• Note the dried lime, since its sour, distinctive flavour surprises guests expecting a more straightforward savoury stew.
