Using a cheesecloth (or paper towels), squeeze all excess liquid out of the grated potatoes. In a large bowl, combine grated potatoes with remaining waffle ingredients.
Add half the potato mixture to the waffle iron and cook for 15 minutes. Cook time may vary depending on your waffle iron. You want your waffle to have a nice golden crisp on the outside.
Hollandaise
In a blender, add egg yolks, lemon juice, dijon mustard, and paprika together.
Blend on high, while slowly pouring in your melted butter. This should create a nice creamy hollandaise.
Assembly
Cut the waffle in quarters and layer smoked salmon on each slice.
Place poached egg on top of the smoked salmon then pour on a spoonful of hollandaise.
Garnish with a piece of dill and serve with some arugula or salad on the side.
