A medieval fish patties recipe found on cookit.e2bn.org
These fish cakes are based on the osterhlaf (a seafood loaf). Salmon is mentioned by Ælfric (an English abbot, and prolific writer who lived around 955 to 1010) but other fish could be used. These are individual patties rather than one large loaf which is difficult to manage cooking on a modern cooker. The oatmeal gives them a light crunchy texture, quite different from fish cakes made with potato.
