Ingredients:
- 1 cup (227g) cold unsalted butter, cubed
- 1/2 cup (100g) granulated sugar (superfine preferred)
- 2 1/4 cups (280g) sifted all-purpose flour
- 1/4 teaspoon fine sea salt (optional)
Instructions:
- Preheat oven to 325°F (160°C). Line an 8x8 inch (20cm square) baking pan with parchment paper, ensuring an overhang remains.
- In a large bowl, beat the cold, cubed butter and sugar together on medium-low speed until just combined and slightly creamy. Do not overbeat.
- Gradually add the sifted flour and salt to the butter mixture. Mix on the lowest speed or use a wooden spoon until the mixture resembles coarse, damp sand. Stop mixing the instant no dry flour is visible.
- Dump the dough into the prepared pan. Press firmly and evenly into the base using the bottom of a measuring cup or your knuckles. Ensure the edges are crisp.
- Prick the entire surface liberally with a fork (docking). Chill the dough in the refrigerator for a minimum of 45 minutes.
- Before baking, use a sharp knife to score the shortbread into desired fingers or squares.
- Bake for 18–22 minutes. The shortbread should be set and just barely golden at the edges; the center should remain pale.
- Immediately upon removing from the oven, re-cut along the scored lines while still hot. Let cool completely in the pan before lifting out using the parchment overhang.
