How to make pistachio and white chocolate cookies step by step

Step 1 - preparations

• Turn on the oven to convection heating at 170℃.
• Line two large baking sheets from the oven with parchment paper.
• Roughly chop the pistachios - some of them can remain whole.
  100 g pistachios
  
• Chop the white chocolate into smaller pieces.
  100 g white chocolate
  
• Mix together the flour, baking soda, and salt.
  300 g wheat flour, ½ teaspoon baking soda, ½ teaspoon salt
• Melt the butter - e.g., in the microwave and let it cool slightly.

Step 2 - preparing the cookie dough

• Pour the melted butter into a larger bowl, add sugar, and mix with a spoon until combined
  150 g sugar, 170 g butter
  
• Add the egg and egg yolk and mix.
  1 egg, 1 egg yolk
  
• Pour in the mixed flour and stir - the dough will be thick.
  
• Add pistachios and chocolate to the bowl - mix thoroughly.
  
• Scoop portions of dough with a large spoon (I used an ice cream scoop).
  
• Arrange the cookies on the baking sheet, leaving slight gaps - I got 16 cookies.
  

Step 3 - baking pistachio and chocolate cookies

• Place the baking sheets in the preheated oven - I put one closer to the top and the other closer to the bottom, leaving some space between them, and bake for about 8-9 minutes.
• After this time, swap the baking sheets and bake for another 5-7 minutes - until they are nicely browned.
• Remove the baked cookies with the baking sheets from the oven and leave them to cool slightly - during this time they will stop being very soft and will become crispy.
