Cooked porridge in homage to Meal Monday (traditionally the second Monday in February):

During the 17th century, Scottish university students lived in very basic accommodation and were required to bring their own fuel, faggots or peat, to maintain a fire. Their diet was meagre too, largely consisting of oatmeal, which they would make into porridge. … As the students’ country homes or farms were some distance from the city Universities, an occasional long weekend was scheduled to permit them to replenish their supplies.
