Dried rose

• gol-e sorkh

  Literally "red flower". Persian cooking distinguishes dried petals, dried buds and rosewater, and they are used differently.

Barely a flavour at all in the ordinary sense — rose contributes perfume that is perceived retronasally, plus a slight astringency from the tannins in the petal. Used well it makes a dish smell of something without changing what it tastes of, which is exactly why it works with sugar, dairy, almond and lamb alike. Used heavily it tastes of soap and of grandmothers.

Sweet, honeyed and unmistakably floral, with a faint green and slightly spicy background. Damask rose is rounder and less sharp than the rose note in a modern perfume, which is usually reinforced with synthetics.

Dried petals range from pale pink to a deep crimson depending on variety and drying. Uniform vivid pink often means dyed craft material rather than a culinary product.

Dried petals are papery and stay papery; ground rose is a fine fragrant powder. Whole buds are hard and are used whole in a pot and removed, or ground.

• Citronellol and geraniol — The principal rose alcohols and the backbone of the aroma — sweet, floral and slightly citric. They are the compounds present in quantity.
• β-Damascenone — Present in vanishingly small amounts and responsible for a disproportionate share of what people recognise as rose. Its detection threshold is extraordinarily low, which is why rose is so easy to overdose: the compound doing the work is one nobody can measure by eye.
• Rose oxide — A green, slightly metallic top note that distinguishes real rose from a synthetic imitation of it.
• Phenylethyl alcohol — Honeyed and soft, and the dominant compound in rosewater — which is part of why rosewater and dried petals are not the same ingredient.

Infuse and strain wherever you can. Petals steeped in warm milk, cream or syrup and then lifted out give you the perfume without the papery texture or the tannic edge, and — more importantly — they give you a moment at which to stop. Where the rose has to stay in, grind it fine and use a quarter of what looks reasonable: the compound doing most of the work is detectable at concentrations too low to reason about, which is why rose goes from fragrant to soapy over a very short distance. Add it late; long heat leaves the astringency and takes the perfume.

A defining aromatic of Persian cooking, where ground rose petal is a component of advieh and appears through rice dishes, stews and drinks. It goes into ras el hanout in Morocco, into some baharat formulations in the Levant, into Turkish delight, milk puddings and pastry syrups, and into Mughlai biryani, kheer and sweets in South Asia. It works with sugar, dairy, almond, pistachio, cardamom, saffron and — less obviously and very well — with lamb.

• infusing — The most controllable technique and the traditional one. Petals or buds steeped in warm milk, cream, syrup or tea and then strained give the perfume without the papery texture or the tannin, and let the cook stop before the astringency arrives.
• grinding — Ground to a powder, rose disperses evenly through a spice blend — which is how it works in advieh, in ras el hanout and in some baharat formulations. It fades faster ground than whole.
• baking — Survives an oven adequately, particularly when protected inside a dough or a filling. The perfume is more prominent in something eaten warm than cold.
• boiling — Prolonged heat drives off the light compounds that carry the character and extracts tannin, leaving something astringent and faintly stewed. Rose is added late, or infused off the heat.

Crush a few petals in the palm and smell immediately. Live rose is unmistakable from a hand’s distance; old rose smells faintly of tea and dust, and the colour will still be perfect. This is the clearest case in the catalogue of a spice whose appearance outlives its usefulness by a year or more, which is why so many jars of beautiful pink petals contribute nothing.

• No smell on crushing, however good the colour looks
• A tea-like or dusty aroma
• Petals browning at the edges

• Volatilisation of damascenone and the rose alcohols, which is most of the aroma
• Fading of the pink or crimson colour
• Oxidation towards a stewed, tea-like character

Buy whole petals or buds and grind what you need. Rose loses its aroma faster than almost anything else in the cupboard and ground rose loses it fastest of all, so a jar of rose powder bought a year ago is a pink colouring rather than a spice. The purchase that actually matters is provenance: buy food-grade rose from a food supplier, because craft petals look identical, cost less, and were never intended to be eaten.

• Sold explicitly as culinary or food-grade, by a food supplier.
• A strong smell on crushing a petal — this is the only test that matters, and colour will tell you nothing about it.
• Natural variation in petal colour rather than a uniform vivid pink, which suggests dye.
• Whole buds where a recipe wants them; they are stronger and keep better than loose petals.

Culinary rose is graded informally on species, on petal against whole bud, on colour and on aroma, and there is no widely applied international standard. The formal grading in this trade concerns rose oil and rosewater, where composition can be tested, and it does not reach the dried flower.

Rosaceae

A thorny deciduous shrub to about two metres, with intensely fragrant pink to deep pink double flowers borne in a single short season. The damask rose is a hybrid of ancient and uncertain parentage and is propagated vegetatively.

The damask rose is of ancient hybrid origin in the Middle East, and its cultivation for perfume and food is centred on Iran, Türkiye and Bulgaria.

• Iran — major producer. Kashan and the surrounding region, where the rose harvest and rosewater distillation are a major annual event.
• Türkiye — major producer. Isparta, the centre of Turkish rose oil and rosewater production.
• Bulgaria — major producer. The Valley of the Roses at Kazanlak, historically the world’s principal source of rose otto.
• Morocco — notable producer. The Dades valley, where rose is grown for both culinary and perfumery use.
• India — notable producer

Picked by hand at dawn, when the volatile oil content is at its peak and before the sun drives it off. Petals for drying are picked slightly later than petals for distillation.

1. Picking — Flowers or buds picked by hand at or shortly after dawn.Why: Volatile content falls through the morning; the timing is not tradition but yield.
2. Sorting — Petals separated from buds, and buds graded by size and colour.
3. Drying — Shade-dried, spread thinly.Why: Direct sun destroys both the colour and the aroma, and the colour is much of what the product is sold on.

Graded informally on species, on whether the product is petal or whole bud, on colour and on aroma. Whole buds command a premium and are used decoratively as much as for flavour. There is no widely applied international standard for the culinary product; the formal grading in this trade is for rose oil and rosewater.

The commercially significant problems are provenance rather than composition: ornamental or craft-grade petals sold without any statement that they are food grade, dyed petals sold as naturally coloured, and — in the rosewater trade specifically — synthetic rose essence diluted and sold as distillate. The last of these is the most consequential and the easiest to detect by smell.

A perennial shrub grown in rows and harvested by hand. The labour intensity is extreme and is why rose products are expensive: the flowers must be picked at dawn, and the yield of oil per tonne of petals is tiny.

Temperate with cold winters and a short intense flowering season. The rose crop is picked over a few weeks in late spring and, for oil, in the few hours after dawn while the volatile content is highest.

Rose has been distilled and eaten across the Persian and Arab world for well over a thousand years, and the technology of distillation itself is bound up with it — the industrial-scale production of rosewater in medieval Persia and the Arab world is one of the earliest large applications of the still. Rose reached Europe as a medicine and a perfume and was a common flavouring in medieval and Tudor cookery before falling almost entirely out of European savoury use, where it now survives mainly as Turkish delight and as a note in confectionery.

A high-value trade dominated by rose oil and rosewater rather than by the dried flower. Bulgaria, Türkiye and Iran are the principal producers, and rose otto is among the most expensive essential oils in the world by weight.
