loomi

Loomi, also known as black lime, dried lime, or Omani lime (Citrus aurantifolia), is a dehydrated citrus fruit native to the Arabian Peninsula, particularly Oman. The ingredient is produced by sun-drying whole limes, a process that causes the fruit to darken to a deep brown or blackish color and become extremely hard and shriveled. The drying process concentrates the citric acid and creates a complex, smoky, slightly bitter flavor profile distinct from fresh limes. The interior of a dried loomi is hollow and filled with a small amount of dried pulp.

Loomi is typically one of three main varieties based on size and production method: the most common is the whole sun-dried black lime, followed by split loomi (halved before drying), and powdered loomi. The ingredient has a distinctive musty, earthy undertone with floral notes that develop during the curing process, making it a cornerstone of Middle Eastern, Persian, and Indian spice cupboards.

Loomi is fundamental to Persian, Iraqi, Kuwaiti, and broader Gulf cuisine, where it imparts depth and subtle citrus complexity to dishes without the brightness of fresh lime juice. Whole loomi are commonly added to rice pilafs, stews, and slow-cooked meat dishes (particularly lamb), where they soften and infuse broths with their distinctive flavor. The ingredient is also ground into a fine powder and used as a dry seasoning for grilled meats, fish, and vegetables, or sprinkled over rice dishes.

In Iranian cookery, loomi appears in classic dishes such as khorak-e bademjan (eggplant stew) and ash-e reshteh (herb and noodle soup). The ingredient pairs particularly well with cardamom, cumin, cinnamon, and turmeric, and is increasingly recognized in contemporary Middle Eastern and fusion cooking. A single loomi can be lightly cracked and added whole to a dish, or pierced to allow quicker infusion, then removed before serving.
