Ingredients

For the crust:

  • 220 g 1 cup flour
  • ½ teaspoon salt
  • 50 g ¼ cup sugar
  • 115 g 1/2 cup unsalted butter, cold

For the pistachio topping:

  • 110 g (3/4 cup) shelled unsalted pistachios
  • tablespoons flour
  • a pinch of salt
  • 75 g (6 tbsp) sugar
  • 70 g (5 tbsp) butter
  • 1 large egg
  • 1 teaspoon vanilla

For the fruit topping:

  • 200 g rhubarb peeled and chopped
  • 300 g strawberries hulled and chopped
  • the zest of 1/2 lemon
  • 1 tbsp of lemon juice
  • 1 tbsp granulated sugar
  • Icing sugar to dust

Instructions

Prepare the crust:

  1. Preheat oven to 180°C. Butter and flour a 20cm square baking tin.
  2. In a food processor, combine the flour, salt and sugar. Cut the butter into cubes and add to the flour mix and process for about 1 min, until it forms large clumps. 

  3. Pour the dough into the baking square and press down firmly until the base is even.

  4.  Bake for 15 minutes or until very pale golden.

Prepare the fruit mix:

  1. Hull the strawberry and chop them into quarters. Place in a bowl.
  2. Peel and cut the rhubarb into 1 cm pieces. Add to the strawberry.
  3. Add 1 tbsp sugar, 1 tbsp lemon juice and 1/2 lemon zest, toss, cover and set aside.

Prepare the pistachio topping:

  1. Grind the pistachios, flour, salt, and sugar into a powder in your food processor. Add the butter and process until no longer visible. Add the egg and vanilla, blending until it forms a smooth paste.
  2. Spread the filling evenly over the cooked shortbread base.

Bake:

  1. Evenly spread the fruit mix (without the juices) over the pistachio paste.
  2. Bake the slice for 50 minutes, or until golden and a skewer inserted into the pistachio comes out clean. Leave in pan to cool.
  3. Dust with icing sugar to decorate and cut into squares.
  4. Keep left over slice in the fridge in an airtight container.
