Mast-o-Esfenaj

Easy·25 min

Cooked spinach wilted down with golden fried onion and garlic, then folded cold into thick strained yogurt — a member of the Persian borani family of yogurt-and-vegetable sides. It sits somewhere between a dip and a salad: pale green, creamy, lightly tart, eaten chilled with flatbread or spooned beside rice and grilled meat to cool the palate. A scatter of walnuts and a drizzle of saffron or fried mint often crown it. Quick to make, it keeps well and tastes better after a few hours in the fridge.

Borani names a whole class of Iranian dishes in which a cooked vegetable is dressed with yogurt, and the spinach version is among the most common. Food historians trace the name to Buran, a noblewoman of the early Islamic centuries — popularly the wife of the caliph al-Ma'mun — whose fondness for such dishes is said to have lent them her name. The form is documented across centuries of Persian court cookery: a whole chapter on borani appears in the Safavid-era manual Maddat al-hayat, written by Nurollah, cook to Shah Abbas I, where some recipes swap whey for yogurt or fold in egg.

Cool and creamy, with the soft, slightly mineral pull of cooked spinach running through tangy yogurt. The fried onion brings a sweet, mellow depth and the garlic a gentle warmth that has lost its raw edge. Walnuts, if added, give an oily crunch and a whisper of bitterness; a thread of saffron or a sprinkle of dried mint lifts the whole spoonful. It is gentle, refreshing, and meant to soothe rather than assert.

Straining the yogurt first drives off excess water so it stays thick and clings instead of weeping once the spinach goes in. The spinach is cooked down and its moisture squeezed out for the same reason — a watery green would thin the whole dish. Frying the onion and garlic before they meet the yogurt tames their raw bite and folds in a sweet, caramelized base, and chilling lets the flavors marry and the acidity round out.

Variations

Some cooks keep it plain spinach and yogurt; others build it richer with walnuts, a saffron drizzle, or fried dried mint poured over as a final flourish. A close cousin, borani-e bademjan, swaps in fried eggplant, and other boranis use beetroot, mushroom or cooked greens on the same yogurt base. Garlic can be raw and sharp or fried and mellow depending on the household.

How it's made

7 steps · 25 min

  1. 1
    30 min

    Strain plain yogurt in a cloth-lined sieve for about half an hour until it thickens.

    Watch out

    Strain until the yogurt sits thick enough to hold a spoon-track — weepy yogurt will thin the whole dish once the spinach goes in.

  2. 2
    8 min

    Wash and chop the spinach, then wilt it in a dry or lightly oiled pan until soft and reduced.

  3. 3
    5 min

    Squeeze or press out the excess liquid from the cooked spinach and let it cool.

    Watch out

    Cook the spinach right down and then squeeze it truly dry — any trapped water will weep out later and slacken the yogurt.

  4. 4
    6 min

    Fry the chopped onion in oil until golden, add the garlic, and cook briefly until fragrant.

  5. 5
    3 min

    Combine the cooled spinach, fried onion and garlic, and season with salt and pepper.

  6. 6
    3 min

    Fold the strained yogurt into the spinach mixture until evenly pale green.

    Watch out

    Fold gently just until the color turns an even pale green — overworking loosens the strained yogurt and beats out its body.

  7. 7
    60 min

    Chill for at least an hour, then top with walnuts, a saffron drizzle or fried mint before serving.
