This is a recipe from the old time Fisherman, if a Newfy says "Fish" he means Cod, everything else has a name, Mackeral, Tuna etc.
Bruise refers to the ships bread or biscuit that is still available in stores in parts of Canada, They used to carry an axe on board to chop wood and "bruise" the bread. They are roughly oval, 1 1/2" -2" thick and about 4 inches long, ( And hard as cast iron )
Soak Salt Cod and biscuit over night in separate containers (2 biscuits per Lb of Cod )
Change water, boil till Cod falls off bones (can pick out bones at this time )
Drain biscuits add Cod
Add reduced Salt pork WITH grease
Mix.
You can add potato's and onions if you have them.
The BEST (?) beverage to serve with this is "Screech" Like fine wine, you throw away the cap on opening. (unlike fine wine it might make you go blind

)
If you can not get real Screech make do with a mix of cheap rum and grain alcohol.
This is NOT a joke, this is what those old birds lived on back before WWII When Newfoundland was an Independent Country.
