Ingredients
Method
- Divide slices of bread between four plates and spread with butter all the way to the crust. Arrange the cucumber slices over the butter, overlapping in a fish scale pattern.
- In a medium mixing bowl, vigorously stir the eggs, mayonnaise, sour cream, and salt until combined and the egg yolks have broken apart and become part of the sauce.
- Spoon the egg salad over the cucumbers, then arrange the pickled herring evenly across each sandwich. Top with watercress and garnish with fresh dill.
