In an electric mixer fitted with a paddle attachment, cream ghee confectioner's (icing) sugar, essence, and salt on medium speed for 5 minutes. Change to a dough hook attachment, add the flour, and knead into a soft dough. Leave covered for 4 hours.
Pre-heat oven to 120 deg C (250 deg F). Line baking trays with greaseproof paper.
Using a teaspoon, scoop a heaped teaspoon portion of dough and roll between your palms into a ball, each the size of a marble. Place on the baking tray, spaced well apart. Using a small fork, make impressions by pressing lightly on the centre of each ball, and sliding the fork away from the centre to prevent sticking. (For round-shaped cookies, roll into balls, and press lightly in the centre with your finger).
Bake for 20 - 25 minutes, until cookies turn lighter in colour. Transfer to a cooling rack. When completely cooled, store in airtight containers.
