Shortbread all butter petticoat tails

Shortbread all butter petticoat tails are a buttery shortbread biscuit sold by Sainsbury's in the United Kingdom. Classified as a Sugary snack and a biscuit, it carries a Nutri‑Score of E and falls in NOVA group 3, reflecting its high fat (27.8 g), saturated fat (18.1 g), sugar (16.2 g) and moderate salt (0.59 g) per 100 g, while providing 6 g of protein and 2.3 g of fiber. These values make it energy‑dense (518 kcal/100 g) and less suitable for low‑calorie or low‑sugar diets, though its simple ingredient list of wheat flour, butter, sugar and sea salt may appeal to those seeking a traditional shortbread taste.
