Tips
Make sure potatoes are completely cooled before grating to prevent the mixture from becoming too wet and falling apart during cooking.
Use a heated, well-oiled griddle to ensure the potato cakes develop a crispy golden crust without sticking to the surface.
Fold the smoked salmon slices into thirds and arrange at an angle for an elegant restaurant-style presentation.
Good to Know
Refrigerate assembled plates for up to 2 hours before serving. Store leftover lemon sour cream in squeeze bottle in refrigerator for up to 3 days.
Bake and cool potatoes up to 1 day ahead. Make lemon sour cream up to 2 days ahead. Form and cook potato cakes up to 4 hours ahead, reheat in warm oven before serving.
Serve immediately while potato cakes are warm. Best enjoyed fresh as greens will wilt if left assembled too long.
Common Mistakes
Don't grate hot potatoes as they'll create a mushy mixture that won't hold together when cooking.
Don't skip oiling the griddle or potato cakes will stick and break apart when flipping.
