Pashmak — Persian floss spun from sesame and sugar

i. Origin & history

Pashmak (پشمک, meaning "little wool") is most strongly associated with Yazd, a desert city in central Iran famous for its confectionery — Yazdi sweets are sold across the country by name. The technique used to make pashmak is one of the oldest in the sugar repertoire: a hot caramelised paste is folded around a sugar-and-sesame-flour wrap, then pulled and folded repeatedly, doubling the number of strands at each fold, until a single block has been worked into tens of thousands of impossibly fine threads. The same hand-pulled-floss technique is used in Chinese dragon's-beard candy and Turkish pişmaniye, and the three sweets share a common origin in the long history of overland sugar craft that travelled the Silk Road.

In Iran, pashmak is eaten on its own with tea, folded into ice cream (particularly Persian bastani saffron ice cream), or scattered over cakes and rosewater puddings as a delicate decoration. Because of how rapidly sugar absorbs moisture from the air, pashmak must be made in a dry kitchen and eaten quickly — within a few weeks at most. It is one of the most technically demanding sweets in the Persian dessert canon, and even in Yazd it is still made largely by hand.

• 200 g white sesame seeds — for the toasted sesame flour
• 100 g plain flour
• 50 g unsalted butter or ghee
• 400 g granulated sugar — for the sugar paste
• 150 ml water
• 1 tbsp white wine vinegar or lemon juice — prevents crystallisation
• 1 pinch saffron threads, ground (optional, for colour and scent)

iii. Method

1. Toast the sesame seeds in a dry pan over a medium flame, stirring constantly, until they turn a deep gold and smell intensely nutty — about 8 minutes. Tip into a food processor with the plain flour and grind to a fine, sandy meal. Pass through a sieve and discard any coarse pieces.
2. Melt the butter in a wide heavy pan over a low flame. Add the sesame-flour mixture and cook, stirring continuously, for 6–8 minutes until the mixture turns a shade darker and smells fragrant. Tip onto a tray to cool to lukewarm — the texture should be a soft, crumbly paste.
3. Combine the sugar, water and vinegar in a heavy saucepan. Heat gently until the sugar dissolves, then bring to a boil without stirring. Cook to 145 °C / 290 °F on a sugar thermometer — a teaspoon of syrup dropped into cold water should harden into a brittle, glassy thread.
4. Pour the hot syrup onto a marble slab or a large oiled tray. As soon as the edges firm, fold the syrup repeatedly with two oiled scrapers, pulling it inward. Keep working until you have a smooth, taffy-like ring that is just cool enough to handle but still warm and pliable.
5. Stretch the warm sugar ring into a doughnut shape and wrap the sesame-flour paste around it in an even coating. Now begin pulling: lift one side of the ring, fold it across the other to double the loop, and pull outwards. Each fold doubles the number of strands. Continue for 10–12 folds, working quickly while the sugar is still warm and elastic; by the end you should have an enormous mass of impossibly fine threads.
6. Cut the floss with scissors into roughly hand-sized clumps. Eat immediately, or store in an absolutely airtight tin with a small sachet of food-grade silica gel. Pashmak picks up moisture from the air within hours in a humid kitchen.

iv. Tips & common mistakes

• Choose a dry day. Humidity is the enemy of pashmak. On a damp day the floss will collapse before you finish pulling it.
• Work two-handed. Pashmak is traditionally pulled by two confectioners working in rhythm. Solo, you can manage smaller batches.
• Keep the sugar warm. If the sugar ring cools too far, you cannot pull it any further. A warm marble or a low oven nearby can buy time.
• The sesame coating is structural. It is not just for flavour — it lubricates the strands so they slip past one another without re-fusing into a single block.

v. Variations

Pashmak is most often plain, but it can be tinted and flavoured. Saffron pashmak takes a deep gold colour from ground saffron added to the sugar syrup. Rose pashmak is scented with rosewater and tinted pink with beetroot. Pistachio pashmak uses ground pistachio in place of (or alongside) sesame, giving it a green hue and a more buttery flavour. Closely related sweets include the Turkish pişmaniye, made the same way but often pulled longer for a finer, more cotton-candy-like result, and Chinese dragon's-beard candy, in which the floss is wrapped around a small filling of crushed peanuts and coconut.
