This is red pudding from wikipedia:~
Red pudding is a meat dish commonly served mainly only at chip shops in parts of Scotland as an alternative to fish (see fish and chips). The ingredients consists of bacon, beef, port, pork rind, suet, rusks, spices, salt, beef stock, beef fat and colouring.
This clumpy red coloured food is then formed into a large sausage-like shape of roughly eight inches in length, no different to its black and white pudding family. To encase it, the food is coated thick in batter and then deep fried, ready to be taken away served hot. Bought on its own it's known as a single red, or when accompanied by chips it is known as a red pudding supper.
The taste is said to be similar to a saveloy, a type of pork sausage, though battered sausage is also served in Scotland (in addition to red pudding on menus) that could be more akin to saveloy.
