A cooling summer drink built on the tiny reddish seeds of khakshir, the London rocket plant, which swell into a soft gel when wetted. The seeds are rinsed, mixed into cold sugar water scented with rose water, and stirred so they stay suspended throughout the glass. Drunk ice-cold, it is prized across Iran as a thirst-quencher and a gentle folk tonic for the liver and for cooling the body in fierce heat.
Khakshir takes its name directly from the plant Sisymbrium irio, whose seeds have long been gathered as a household remedy in Iranian folk medicine. Sold by the scoop in spice bazaars and apothecaries, the seeds are valued in the Persian humoral tradition as a cooling agent, recommended for fevers, heat rash, and digestion. The drink belongs to the same family of seed-based summer coolers as basil-seed sharbat and is a fixture of hot-weather hospitality.
Faintly nutty and barely sweet, the drink is all about texture: thousands of gel-cloaked seeds give each mouthful a soft, popping, almost jelly-like slip that is bizarrely soothing in the heat. Rose water lifts it with a clean floral top note. It finishes light and clean, never cloying.
The seed coat of London rocket is rich in mucilage, a soluble fiber that absorbs many times its weight in water and forms a clear, slippery gel within minutes. Stirring keeps the buoyant seeds dispersed so they do not raft at the surface, while the gel both thickens the water and carries each seed evenly through the glass for that signature suspended texture.
Variations
Sweetened with sugar, honey, or syrup; scented with rose water alone or with a squeeze of lime; sometimes mixed with basil seeds (tokhm-e sharbati) for extra body; served plain over ice or splashed into lemonade.

Ingredients

6 steps · 10 min
- 12 min
Tip the khakshir seeds into a fine sieve and rinse briefly under cold water to wash off dust.
- 22 min
In a pitcher, stir sugar into cold water until fully dissolved.
- 31 min
Add the rinsed seeds and rose water and stir well.
- 410 min
Let stand 10 minutes so the seeds swell and form their gel coating.
Watch outGive it a full 10 minutes — the seeds swell and throw off a clear, slippery gel; too soon and the drink stays thin and watery.
- 51 min
Stir again to redistribute the seeds, which will have settled.
- 61 min
Pour over plenty of ice and serve at once, stirring before each glass.
Watch outStir right before every pour — these seeds are buoyant and raft to the top fast, so an unstirred glass comes out lopsided.
