Flake the bluefish into the bowl of a food processor. Add the cream cheese and sour cream and pulse to combine. Add the onions, lemon juice, and Worcestershire, then pulse again to combine to a chunky consistency. Season with cayenne, salt, and pepper to taste. Hand mix in umami, shallots, onions, and chives. Serve immediately or store in an airtight container for up to 5 days.
Notes
If you let it sit for a few hours, the flavor will be better!
