Roll in flour; or they can be egged and crumbed like croquettes.

Drop into boiling lard; drain on brown paper, and serve hot.

Fresh fish can be used in the same way, and is very nice.
Breadcrumbs, softened in milk, can be used instead of potato, but are not so good.
FISH HASH.
Use either fresh fish or salt.

If the former, double the measure of salt will be needed.

Prepare and mix as in fish balls, allowing always double the amount of fresh mashed potato that you have of fish.
