📝 About This Recipe

Hailing from the coastal regions of Hormozgan and Larestan, Mahyawa is a legendary fermented fish sauce that captures the soul of the Persian Gulf. This pungent, earthy, and deeply savory condiment is crafted from sun-dried sardines and a proprietary blend of warm spices like fennel and mustard seeds. It is a labor of patience and tradition, transforming humble ingredients into a complex liquid gold that defines the flavor profile of Southern Iranian cuisine.

🥗 Ingredients

The Fish Base

  • 500 grams Small Dried Sardines (Motu) (Heads removed, thoroughly cleaned and sun-dried until brittle)
  • 250 grams Coarse Sea Salt (Non-iodized is essential for proper fermentation)
  • 1.5 liters Filtered Water (Boiled and cooled to room temperature)

The Aromatic Spice Blend

  • 150 grams Mustard Seeds (Black or Brown) (Lightly toasted and coarsely ground)
  • 100 grams Fennel Seeds (Toasted and finely ground)
  • 50 grams Cumin Seeds (Toasted and ground)
  • 30 grams Coriander Seeds (Ground)
  • 1 tablespoon Black Peppercorns (Cracked)
  • 2 tablespoons Dried Orange Peel (Finely powdered for a citrusy undertone)
  • 1 tablespoon Turmeric Powder (For color and preservation)

👨‍🍳 Instructions

  1. 1

    Begin by ensuring all your equipment—glass jars, spoons, and bowls—are sterilized. Any unwanted bacteria can spoil the long fermentation process.

  2. 2

    Grind the sun-dried sardines into a coarse powder using a heavy-duty blender or a traditional mortar and pestle. You want a texture similar to coarse sand, not a fine flour.

  3. 3

    In a large glass or ceramic crock, combine the ground fish powder with the coarse sea salt. Mix thoroughly to ensure the salt is evenly distributed, as this prevents spoilage.

  4. 4

    Gradually pour the 1.5 liters of cooled, filtered water over the fish and salt mixture. Stir well until the salt has mostly dissolved.

  5. 5

    Cover the mouth of the jar with a clean, breathable muslin cloth or cheesecloth and secure it with a rubber band. This allows gases to escape while keeping insects out.

  6. 6

    Place the jar in a warm, sunny spot (ideally outdoors if the weather is hot, or a sunny windowsill). Let this sit for 15-20 days. Stir the mixture once every two days with a clean wooden spoon to aerate it.

  7. 7

    After the initial fermentation period, the mixture will have developed a strong, pungent aroma. Strain the liquid through a fine-mesh sieve into a clean bowl, pressing down on the solids to extract every bit of essence. Discard the remaining solids.

  8. 8

    Prepare the spice blend: Lightly toast the mustard, fennel, cumin, and coriander seeds in a dry pan until fragrant. Grind them into a medium-fine powder.

  9. 9

    Whisk the ground spices, orange peel, and turmeric into the strained fish liquid. The mustard seeds will act as a thickening agent and provide the signature Mahyawa 'kick'.

  10. 10

    Pour the spiced liquid back into a clean glass jar. Cover again with the cloth and return it to the sun for another 5-10 days. This 'mellowing' phase allows the spices to bloom and integrate with the fermented fish.

  11. 11

    The Mahyawa is ready when it has thickened slightly to the consistency of heavy cream and developed a deep, dark chocolate-brown color.

  12. 12

    Bottle the finished sauce in clean glass bottles. It can be stored at room temperature for several months, though many prefer to keep it in a cool, dark place.

💡 Chef's Tips

Always use non-iodized salt, as iodine can inhibit the growth of the beneficial bacteria needed for fermentation. If the mixture develops a fuzzy mold or an 'off' rotten smell (rather than a strong fermented smell), discard it and start over. For a smoother sauce, you can run the final spiced mixture through a blender before the final aging phase. The sun is a traditional 'ingredient' in Southern Iran; if you live in a cold climate, place the jar near a heater or in a very low-temperature oven (40°C) for a few hours a day. Adjust the mustard seed quantity to control the thickness and heat of the sauce.

🍽️ Serving Suggestions

Drizzle over freshly baked 'Nan-e-Pishka' or any thin flatbread, then top with a sprinkle of za'atar. Serve as a dipping sauce alongside fresh radishes, scallions, and walnuts for a traditional breakfast. Brush onto fish or shrimp before grilling to add an incredible depth of umami flavor. Mix a tablespoon into a bowl of melted butter or ghee to create a savory spread for warm toast. Pair with a glass of cold Doogh (Persian yogurt drink) to balance the salty, pungent notes of the sauce.
