Grind together all ingredients listed for the fish balls such as the celery, onions, swerve, fish, salt etc.
Mix the grinded ingredients as much as possible. The longer it is mixed the softer it will become.
Wet hands and form fish balls.
Slice the carrots and onions into a pot. (Carrots are for flavor only and not for actual consumption as they are not keto permitted) Add enough water to cover all ingredients in the pot totally.
Add 4 tablespoons salt and 3 tablespoons swerve. Bring to boil.
Add fish balls to pot while water is still at a boil.
Boil fish for two hours.
Check pot often and add water as much as you see fit. Add less water for a more gooey texture or more for a more liquidy style.
