Rose Petal Jam Tart — almond cream, rose preserve and pistachio

i. Origin & history

Rose petal jam is one of the oldest preserves of the Middle East and the eastern Mediterranean. The petals of the highly scented Damask rose (Rosa damascena) are simmered with sugar and lemon juice into a soft, perfumed jam in which the petals remain visible. In Iran it is morabba-ye gol-e mohammadi; in Turkey, gül reçeli, a speciality of the rose-growing region around Isparta; and in Bulgaria, whose Valley of the Roses is famous for rose oil, rose jam is a beloved national preserve. It is eaten at breakfast with bread and cream, stirred into tea or yoghurt, and offered to guests.

Roses have perfumed sweets in the region for many centuries. Rosewater, distilled from the same Damask roses, flavours Persian rice puddings, ice creams such as bastani, the saffron pudding sholeh zard and countless pastries, and the rose became a symbol of hospitality and refinement.

European cooks also once used rose freely. Rosewater was a standard flavouring in medieval and Renaissance French and English pastries, often paired with almonds — marchpane and almond creams were regularly scented with it — before vanilla largely replaced it in the eighteenth and nineteenth centuries. A rose and almond tart therefore has historical echoes on both sides.

The modern rose petal jam tart is a contemporary fusion rather than a traditional regional dish. It uses the architecture of the French almond tart and the English Bakewell tart — pastry, a layer of jam, almond cream — with the rose preserve and pistachios of Persian and Turkish sweets. It has become popular with bakers who love Middle Eastern flavours, and it is a natural dessert for spring celebrations such as Nowruz, the Persian New Year.

ii. Keeping the rose fragrant through the oven

Rose flavour is delicate and volatile. The aromatic compounds that give rose petals and rosewater their perfume evaporate and fade with prolonged heat, so a tart in which the rose is simply baked for forty minutes can taste only faintly floral. The recipe layers rose in three places to keep it present.

First, the jam goes under the almond cream, not on top. Protected by a thick layer of filling, it heats more gently and keeps more of its scent, and it stays soft and jammy rather than caramelising. Second, a small amount of rosewater goes into the almond cream itself. Rosewater is powerful, and too much makes a tart taste soapy, so a teaspoon is enough. Third, the hot tart is glazed with a little more jam thinned with lemon juice, which brings back a fresh hit of rose at the surface.

Lemon plays a supporting role throughout. Rose jam is very sweet, and its pink colour comes from pigments that stay bright in acidic conditions and turn dull in neutral ones; that is why rose jams are made with lemon juice. A little lemon zest in the almond cream lifts the flavour and keeps the tart from tasting cloying.

The jam layer must be thin. Spread too thickly, it boils up through the almond cream as it bakes and can scorch at the edges. About 2–3 mm is right — enough to see a pink line in every slice.

• 200 g plain flour
• 70 g icing sugar
• 1 pinch salt
• 110 g cold unsalted butter, diced, for the pastry
• 1 egg, for the pastry
• 150 g rose petal jam, plus 2 tbsp to glaze
• 100 g unsalted butter, very soft, for the almond cream
• 100 g caster sugar
• 100 g ground almonds
• 2 eggs, for the almond cream
• 15 g plain flour, for the almond cream
• 1 tsp rosewater
• 1 lemon, zest and 1 tsp juice
• ¼ tsp ground cardamom (optional)
• 30 g pistachios, chopped
• 1 tbsp dried edible rose petals, to decorate

Rose petal jam is sold in Iranian, Turkish, Middle Eastern and Bulgarian shops and online; look for one in which you can see the petals, as these have the most flavour. Rosewater strengths vary considerably between brands, so taste it and use less if yours is strong. For homemade jam, simmer 100 g unsprayed scented rose petals with 300 g sugar, 200 ml water and the juice of a lemon until syrupy. Pistachios are the classic partner for rose in Persian sweets; use the bright green, unsalted kind. The optional cardamom adds a warm, Persian note.

iv. Method

1. For the pastry, rub the flour, icing sugar, salt and cold butter to fine crumbs, add the egg and bring together into a dough. Flatten, wrap and chill for 1 hour.
2. Roll the pastry 3 mm thick and line a 22–23 cm loose-bottomed tart tin. Prick the base and chill for 20 minutes. Heat the oven to 180 °C (350 °F), fan 160 °C. Blind-bake with paper and beans for 15 minutes, then 5 minutes uncovered, until pale golden. Cool for 10 minutes.
3. Spread 150 g rose petal jam evenly over the base of the case in a thin layer.
4. For the almond cream, beat the soft butter and sugar until smooth, then beat in the ground almonds, the eggs one at a time, the flour, rosewater, lemon zest and cardamom.
5. Spoon the almond cream over the jam in dollops and spread gently to the edges, taking care not to mix in the jam. Scatter half the pistachios over the top.
6. Bake for 30–35 minutes, until the almond cream is puffed, golden and set and springs back when pressed.
7. Warm the remaining 2 tbsp jam with the lemon juice and brush it over the hot tart. Scatter with the remaining pistachios and the dried rose petals. Cool for at least 30 minutes before slicing.

v. Tips & common mistakes

• Measure the rosewater. A teaspoon perfumes the whole tart; a tablespoon makes it taste of soap.
• Keep the jam layer thin. Thick jam boils up through the almond cream and can burn at the edges.
• Spread the almond cream gently. Drop it in spoonfuls and coax it together so the jam stays as a distinct pink layer.
• Use real rose petal jam. Rose-flavoured jams thickened with other fruit lack the perfume and the visible petals.
• Add the petals after baking. Dried rose petals scorch in the oven; scatter them on the glazed tart for colour.
• Let it rest before slicing. The jam layer is soft when hot; after 30 minutes it sets enough for clean slices.

vi. Variations

Replace half the ground almonds with ground pistachios for a rose and pistachio tart with a green-tinged filling. Add a thin layer of fresh raspberries over the jam — raspberry and rose is a classic pairing in modern French pâtisserie. Saffron, steeped in a teaspoon of hot water and added to the almond cream, gives a golden Persian twist, and orange-blossom water can replace the rosewater with apricot or quince jam for a different floral tart.

Other rose and pistachio desserts on DessertCat include the rose pistachio cake, the pistachio rosewater cake, Iranian pashmak candy floss, nougat-like gaz, and Turkish delight. For the original almond-and-jam tart, see the Bakewell tart.

vii. Serving & storage

Serve the tart at room temperature, in slices, with a spoonful of crème fraîche, thick Greek yoghurt or clotted cream, and a cup of black tea or mint tea. Fresh raspberries or strawberries on the side suit it well. It is a pretty dessert for spring and summer gatherings, afternoon tea and Nowruz celebrations.

Keep the tart well covered at room temperature for up to 2 days, or in the fridge for up to 4; the almond cream stays moist and the rose flavour mellows. Bring it back to room temperature before serving. The pastry case can be baked a day ahead and the almond cream made up to 3 days ahead and refrigerated. The baked tart freezes for up to a month; add the petals after thawing.
