The king salmon I had caught proved to be a female. This serendipitous occurance allowed my father to execute the plan.
Execution? A trip to the local hardware store to buy a cheap plastic collinder, an hour washing salmon eggs in the sink of our fishing lodge kitchenette, another trip to a local grocery for a box of salt, more fiddling in the kitchen sink, then waiting overnight to see if the result of all this effort is edible.
To my surprise the result was not only edible, but pretty good. Caviar!
An intense salmon taste different but reminiscent to smoked salmon. Served on crackers with cream cheese the bright golden orange caviar was a nice treat after a day out fishing.
