Method

  1. 1

    Grind. Grind 320 g shelled unsalted pistachios finely in a food processor, about 20 s.

  2. 2

    Heat. Heat 830 ml whole milk, 150 g sugar, 80 ml double cream, 80 ml glucose syrup and ¼ tsp fine salt in a large saucepan over medium-high until small bubbles appear at the edge, 5-7 min.

  3. 3

    Steep. Off heat, stir in the ground pistachios, cover and steep for 1 h.

  4. 4

    Strain. Strain through a muslin-lined sieve into a bowl, pressing hard. Gather the muslin and squeeze out the remaining liquid; discard the pulp.

  5. 5

    Custard. Mix 13 g cornflour with 60 ml whole milk. Return pistachio milk to the pan, whisk in 5 large egg yolks, and cook over medium, stirring and scraping, until it reaches 88 °C, 4-6 min.

  6. 6

    Thicken. Whisk in the cornflour mixture and stir 30 s until thickened. Pour into a clean bowl, cool 20 min, then chill over iced salted water, stirring, until 4 °C, about 1.5 h.

  7. 7

    Churn. Whisk and churn until like thick soft-serve, 15-30 min.

  8. 8

    Freeze. Pack into a container, pressing out air, and freeze until firm, about 6 h.

  9. 9

    Serve. Serve with chopped pistachios.

Storage

Keep frozen in an airtight container; if frozen solid, soften in the fridge for 1-2 h before scooping.
