Preparation
Step 01
Preheat the oven to 350°F (175°C)
Step 02
Butter a 9x9 or 8x8 inch square baking pan. Alternatively, you can use a round cake pan and cut the shortbread into triangles.
Step 03
In a food processor, combine the caster sugar, flour, salt, and butter and pulse until it resembles coarse breadcrumbs but is smooth and pliable. If it's too dry and crumbly, pulse it a bit longer.
Step 04
Pour the mixture into the greased baking pan.
Step 05
Firmly press the mixture down with your fingers.
Step 06
Prick the shortbread with the tines of a fork, creating rows. It's also possible to run a knife between each row of fork tines to make cutting the shortbread easier once it's baked. You can also prick the shortbread with a fork right after it comes out of the oven; this will make the holes more noticeable, as holes tend to close during baking.
Step 07
Bake the shortbread for 30 to 35 minutes or until golden and firm to the touch.
Step 08
Let cool, then cut and serve.
