What each ingredient does
- Walnuts or hickory nuts
- Provide the main body and crunch of the filling.
- Celery
- Adds crisp texture and fresh, mild flavour to the filling.
- Mayonnaise
- Binds the chopped nuts and celery into a creamy, moist filling.
- Lemon juice
- Adds acidity that brightens the rich mayonnaise and nuts.
- Melted butter
- Coats the bread to add richness and help keep it from soaking up the filling.
