In a mixing bowl add sugar, flour, lavender and salt mix together. Then add slightly softened butter and rub mix though hands until well combined

Lay some cling film on clean surface and place mix on cling film. Roll mix into a sausage shape crimping ends of cling film so it's rolled tightly. Place in fridge to harden. Once hardened unwrap cling film and cut slices around 1cm thick. They will expand whilst cooking.

Place biscuits onto a baking tray (suggest baking paper to avoid sticking) leave space between biscuits as will expand. Bake in a preheated oven at 150 degrees for around 10-15 Minutes. Once done lift out and sprinkle caster sugar on top and leave to cool. Any question please ask. Enjoy
