Step #2 Prepare a baking tray lined with parchment paper.
Step #3 First of all, beat the butter in a bowl with a wooden spoon to soften it.
Step #4 Beat in the sugar, followed by the sifted flour & semolina.
Step #5 Work the ingredients together with the spoon, pressing them to the side of the bowl, then finish off with your hands until you have a smooth mixture that doesn't leave any bits in the bowl.
Step #6 Divide the mixture into 9, & shape each portion into a ball (dust the work surface with flour if you find the mixture too sticky to work with).
Step #7 Flatten each one slightly & prick the centre with a fork (but not all the way through).
Step #8 To make it look pretty, make a 1 cm crinkly border on the top by lightly pressing a fork making a slight indent working all the way around (working for the edge towards the centre).
Step #9 Make sure that the biscuits are at least 1/2 inch in thickness (with the indentations at the edges).
Step #10 Place onto the prepared baking sheet, very well spaced out as they will spread out quite a bit during baking.
Step #11 Bake them for 50-60 mins on the centre shelf of the oven (keep an eye on it after 45 mins - the edges seem to colour more easily than the top) – it should have turned pale gold & feel firm in the centre.
Step #12 Remove from the oven & dust the top this with caster sugar.
Step #13 Leave it to cool for 5 mins on the baking tray before transferring them onto a wire rack to cool completely.
