This is how she made them:
Chunked up some sweet potato and russet potato, boiled then mashed, stirred into a leftover flaked salmon fillet with some breadcrumb, egg beaters and old bay/s/p. Dipped patties in more breadcrumb and pan fried. Sauce is Greek yogurt with a touch of mayo, added lemon juice, old bay, garlic powder and hot sauce. YUM - and I got a good ten cakes out of one piece of salmon! I liked the combo of sweet and white, gave it both good flavor and texture.
