Method
If the potatoes are raw, peel and cube them and boil in salted water over medium-high heat until soft, about 12 minutes. Drain, mash and cool.
Drain the salmon, remove the skin and large bones, and flake into a bowl.
Add the mashed potato, eggs, sliced green onion, half the dill, half the lemon juice, the Dijon and pepper and mix well.
Shape into 8 patties about 2 cm (3/4 inch) thick and press both sides into the cornmeal. Chill 15 minutes if they feel soft.
Heat the oil in a large non-stick skillet over medium heat until shimmering.
Fry the cakes for 4 to 5 minutes per side, until golden and crisp and hot through, 74°C (165°F) in the centre because they contain egg.
Stir the Greek yogurt with the rest of the dill and lemon juice. Serve the cakes with the sauce and the salad greens.
Tips
- Chill the shaped cakes 15 minutes so they hold together.
