What each ingredient does
- Cooked ham
- Provides savory, meaty flavor and the bulk of the filling.
- Nut meats
- Add crunch and a nutty richness that contrasts with the soft egg.
- Hard-boiled eggs
- Give the filling body and a creamy texture once ground and bound together.
- Mayonnaise dressing
- Adds moisture and fat so the mixture spreads smoothly and stays cohesive.
