Pistachio and Lemon Tart

Californian pistachio and Meyer lemon curd tart in a buttery shortcrust with a pistachio praline topping

Origin: California, United States

From the journey of Pistachio.

California is now the world's second-largest pistachio-producing region, surpassed only by Iran. The story of how a nut so deeply rooted in Persian culture came to define the agriculture of the San Joaquin Valley traces a single thread: in 1929, W.E. Whitehouse, a USDA plant explorer, gathered seeds from the Chehel Sotoun garden in Isfahan and from the bazaars of Tehran, bringing them back to California for evaluation. From these Iranian seed collections, the variety that thrived in the Californian conditions (renamed 'Kerman' after the Iranian city whose orchards had been among Whitehouse's sources) became the basis for the entire American industry. Commercial cultivation expanded slowly until 1979, when the Iranian Revolution ended Iranian pistachio exports to the United States almost overnight, and the California industry found itself with both the supply capacity and the suddenly vacated market it needed to expand rapidly. The San Joaquin Valley counties of Kern, Tulare, and Fresno today produce the majority of the American crop, and the Kerman variety remains dominant. California's culinary culture, shaped by the proximity of extraordinary produce, the influence of Californian cuisine's reverence for local ingredients, and the presence of Persian, Middle Eastern, and Mediterranean diaspora communities who brought pistachio-centred cooking traditions with them, embraced the pistachio as a defining local product in the 1990s and 2000s. The pistachio and Meyer lemon tart (the Meyer lemon, cultivated in California since the early 20th century, being the state's other signature citrus) represents this Californian synthesis: a French-influenced pastry form filled with the bright, floral curd of a California-grown citrus and topped with the caramelised crunch of a local pistachio praline.

Ingredients

Pastry

  • 200 g plain flour
  • 25 g icing sugar
  • 100 g cold unsalted butter, cubed
  • 1 egg yolk
  • 2 tbsp ice water
  • 1 pinch fine sea salt

Lemon Curd

  • 4 Meyer lemons (or 3 standard lemons), zest and juice (approximately 120 ml juice)
  • 150 g caster sugar
  • 3 whole eggs plus 2 egg yolks
  • 150 g unsalted butter, cubed and cold

Pistachio Praline

  • 120 g raw pistachios, blanched and peeled
  • 80 g caster sugar
  • 2 tbsp water

Method

  1. Make the pastry: pulse flour, icing sugar, salt, and butter in a food processor until the mixture resembles coarse breadcrumbs. Add the egg yolk and ice water and pulse until the dough just comes together. Turn onto a lightly floured surface, press into a disc, wrap, and refrigerate for 30 minutes.
  2. Roll the pastry to 3 mm thickness and line a 23 cm loose-bottomed tart tin. Trim the edges. Refrigerate for 15 minutes. Preheat the oven to 180°C (fan 160°C). Line the tart with baking paper and baking weights. Blind-bake for 15 minutes, remove the weights and paper, and bake for a further 5 to 8 minutes until the base is dry and pale golden. Cool in the tin.
  3. Make the lemon curd: combine the lemon zest, lemon juice, sugar, eggs, and yolks in a heatproof bowl set over a pan of barely simmering water. Whisk constantly for 10 to 12 minutes until the curd thickens enough to coat the back of a spoon and holds a trail when the whisk is lifted.
  4. Remove from the heat. Add the cold butter cubes one at a time, whisking after each addition until incorporated. The curd will be very thick, smooth, and glossy. Strain through a fine sieve into the cooled pastry case. Smooth the surface. Refrigerate for at least 1 hour until set.
  5. Make the pistachio praline: line a baking sheet with baking paper. Combine the sugar and water in a small saucepan over medium heat, stirring until the sugar dissolves. Continue cooking without stirring until the syrup turns a deep amber caramel, about 5 to 7 minutes. Add the pistachios, swirl once to coat, then pour immediately onto the lined sheet. Cool completely until hard.
  6. Once the praline is completely cold and hard, break into irregular shards. Scatter the praline pieces over the set lemon curd tart just before serving.

Notes

Meyer lemons, a cross between a lemon and a mandarin or sweet orange, have a rounder, more floral acidity than standard Eureka or Lisbon lemons and a much thinner skin. They are widely grown in California but may be harder to source elsewhere; standard lemons with a slightly reduced quantity (90 ml juice rather than 120 ml) and an additional strip of orange zest in the curd make a very good substitute. The praline can be made up to a week in advance and stored in an airtight container; scatter it over the tart only at the last moment to preserve the crunch.
