Rye bread
Provides the sturdy base and structure that holds the filling together.
Butter
Adds richness and a fat barrier that helps keep the bread from soaking up moisture.
Chopped cucumber
Adds cool, crisp moisture and fresh texture to the sandwich.
Chopped green onions
Adds sharp, aromatic bite that balances the richness of the dressing.
Mayonnaise dressing
Adds fat and creaminess that binds the filling and moistens the bread.
