Lincoln biscuit
A Lincoln biscuit is a circular shortcake biscuit, most commonly decorated on one side with a pattern of raised dots. It is commonly purchased in Ireland. The McVitie's version had the word 'Lincoln' embossed on the center of the biscuit. Lincoln biscuits can be found in Irish supermarkets and are manufactured by Jacob's. The basic recipe has come under academic scrutiny and commercial analysis. In 2004, the Campden and Chorleywood Food Research Association set up a research project to understand the textural properties that influence consumer acceptance of short dough biscuits (e.g. Lincoln type). Ingredient functionality influences the hardness, crunchiness, and breakdown properties which can vary and be used to measure acceptability. In Argentina, Kraft Foods produces Galletitas Lincoln, rectangular Lincoln biscuits with the familiar dot pattern, under the Terrabusi brand name. Bibliography
