For an extra layer of flavor, consider adding a pinch of dill or a dash of hot sauce. If you don't have nova lox, smoked salmon can be substituted. Be sure to remove any skin and bones before chopping. This dip can be made up to 24 hours in advance. Just store it in an airtight container in the refrigerator. Serve with bagel chips, crackers, cucumber slices, or carrot sticks for a delightful appetizer spread.
