Originally delivered by horse and cart to Scottish villages in the 1800s, Walker’s shortbread is now globally acclaimed – and a World Market bestseller. Still family owned and a UK-household favorite, this gluten-free, chocolate-chip variety is a modern update to the line. Using a rice-flour blend in the simple recipe – along with sugar, creamery butter, dark chocolate chips, and a hint of salt – means even those on a restricted diet can indulge.
