Bake: Shortbread can be used in a vast amount of ways

Shortbread in its simplest form has just three ingredients — butter, sugar, and flour, says Michelle Darmody.

If you substitute the butter for another form of fat, the name of the biscuit changes and it is called shortcake rather than shortbread.

The original shortbread is one part butter, two parts sugar, and three parts flour. Modern recipes tend to be slight variations on the original.
