Kashk-e Bādemjān [Eggplant & Whey Dip]

Classic Eggplant & Whey Dip

Origin: Pan-Iranian Classic

Kashk-e Bādemjān is arguably the most recognizable eggplant dip in the Persian repertoire. While the dish as we know it was popularized during the Qajar Dynasty, the soul of this recipe is deeply anchored to the resourcefulness of the Desert Center (Kavīr). Its defining ingredient, kashk, is an ancient culinary triumph developed by nomadic pastoralists who fermented and sun-dried yogurt into rock-hard, shelf-stable rounds to preserve valuable dairy proteins in the parched interior without refrigeration.

Reconstituted with water, this fermented whey carries a powerful, sharp, and savory tang. It provides the necessary, complex counterpoint to the sweetness of slow-cooked onions and the heavy richness of the eggplants. While you can substitute sour cream or thick Greek yogurt in a pinch, utilizing real kashk is what elevates this dish from a simple vegetable mash into a deeply satisfying, authentic staple of the Persian table.

Serves: 4–6 as a dip
Preparation time: 45 minutes
Cooking time: 40 minutes

Ingredients

Fresh Produce

• 3 medium Japanese eggplants
• 1/2 yellow onion
• 2 cloves garlic

Dairy

• 2 tbsp kashk (plus more for garnish)

Pantry

• 1/4 cup light olive oil or vegetable oil (plus more for frying)
• 1/2 tsp turmeric
• 1/4 tsp black pepper
• 1 tsp kosher salt (plus more for salting eggplant)
• 1 tbsp dried mint (for garnish)
• 1 tbsp extra virgin olive oil (for garnish)

Preparation

• Wash and peel the eggplants and remove the stems.
• Cut lengthwise into 1cm thick slices. Lay the slices on a tray or cutting board, sprinkle lightly with salt, and let sit for 20–30 minutes to draw out excess moisture.
• While the eggplant sits, finely chop the onion and mince the garlic.
• After 20–30 minutes, pat the eggplant slices completely dry with a paper towel.
• Measure and stage all remaining pantry and dairy ingredients.

Instructions

1. Cook the eggplant. Heat a generous layer of cooking oil in a large skillet over medium-high heat. Working in batches, fry the eggplant slices until golden brown on both sides. Transfer to a plate lined with paper towels to drain excess oil.
2. Sauté the aromatics. In a separate pan, sauté the onion in 2 tsp of oil over medium heat until lightly browned, about 5–7 minutes. Add the minced garlic and cook for 2 more minutes. Add the turmeric and black pepper, stir and cook for 1 more minute, then set aside.
3. Simmer the dip. In a shallow pot over medium-low heat, arrange the fried eggplant slices. Sprinkle with 1 tsp of kosher salt (or 1/2 tsp table salt) and top with the cooked onion and garlic mixture. Cover and cook for 10 minutes. Uncover, use a wooden spoon to partially mash the eggplant and stir everything together. Add 1/2 cup of water, cover, and cook for another 10 minutes. Repeat this process one more time—mashing, stirring, adding water, and cooking for a final 10 minutes.
4. Prepare the mint oil. While the eggplant simmers, prepare the fried mint (na’nā dāgh). Grind the dried mint into a powder. Heat 1 tbsp of extra virgin olive oil in a very small pan over medium heat. Add the mint powder and stir for just 30 seconds until fragrant and saturated with oil. Immediately remove from the heat to prevent burning.
5. Finish and serve. Turn off the heat for the eggplant. Stir in 2 teaspoons of liquid kashk. Taste and adjust seasoning if necessary. Plate the eggplant dip. Artfully drizzle the remaining kashk and the mint oil over the dip. Serve warm with flatbread.

Tips

• For a lighter version, you can roast or broil the eggplant instead of frying. Pierce the eggplants with a fork, brush lightly with oil, and roast at 400°F (200°C) or broil until the skin is blistered and the flesh is completely tender. Scoop out the flesh and proceed with the recipe.

🍞 The Essential Pairing > A rich dip requires a flatbread capable of holding its weight. While store-bought ones suffice in a pinch, the optimal, authentic pairing is a thick, blistered Nān-e Barbarī. My in-development recipe for this is available to subscribers.

🥛 The Expert Choice > The soul of this dish is the Kashk. While commercial versions are functional, authentic homemade Kashk is better. My recipe is available exclusively to subscribers.
