BLUE, MACKEREL, SALMON, STEELHEAD, TROUT, AND OTHER FATTY
FISH EXCEPT TUNA
Eviscerate fish within 2 hours after they are caught.
Keep cleaned fish on ice until ready to can.
NOTE: Glass-like crystals of magnesium ammonium
phosphate sometimes form in canned salmon. There is no way
for the home canner to prevent these crystals from forming,
but they usually dissolve when heated and are safe to eat.
PROCEDURE: Remove head, tail, fins and scales. Wash
and remove all blood. Split fish lengthwise, if desired.
Cut cleaned fish into 3-1/2-inch lengths. Fill hot, pint
jars, skin side next to glass, leaving 1-inch headspace.
Add 1 teaspoon of salt per pint, if desired. Do not add
liquids. Adjust lids and process.
