Equipment

Ingredients
 

  • 227 grams (1 cup) Unsalted butter softened, minimum 82% fat
  • 227 grams (2 cups - 3 tablespoons) All-purpose flour (plain flour)
  • 110 grams (½ cup + 1 tablespoon) Coarse Polenta flour
  • 110 grams (½ cup + 1 tablespoon) Fine white sugar (caster sugar)

Instructions
 

  • Preheat the oven to 300℉/150℃ (no fan). Grease the baking tin, then line it with baking parchment paper.
  • Put the softened butter, sugar, and flours into a food processor fitted with the paddle attachment.
  • Blend the shortbread ingredients on low speed for 10-20 seconds, then on medium for 1-2 minutes until a lumpy dough forms.
  • Press the shortbread dough into the lined baking tin and smooth off the top with the back of a spoon. Score the surface with cutting lines and prick all over with a fork.
  • Bake the polenta shortbread for 40 minutes until the top is golden brown. Move the pan onto a wire cooling rack, and immediately cut through the scored lines to the base of the tin again to form the cookies while it is in the pan but still soft. Leave to cool completely.
  • Lift the shortbread out of the pan using the edges of the parchment paper, cut through the cookies again if needed, and serve.

Notes

Always weigh ingredients by the gram using a digital scale rather than measuring by volume for best results. 
It's very important the butter is soft. If it is too cold/hard, the mixture will not combine properly. 
The better the quality and fat content of your butter, the better this shortbread recipe will turn out. 
All ovens vary, so use an oven thermometer to make sure you are baking at the right temperature.
