Made these biscuits today - I used to make them with the little ones - no egg required!
100g butter 50g sugar (I only used 30g) 150g SR flour (I used wholemeal)
Preheat oven to Gas 4 / 180 C / 160 fan. Lightly butter two baking trays. Beat the butter in a bowl until soft / add the sugar and beat again, then gradually add the flour. Bring the mix together with your hands = soft dough. Form into 16 pieces (walnut size) and place on the trays. Dip a fork into water and press on the dough balls to flatten. Cook for 15-20 mins.
