Salmon and Whitefish Cakes with Horseradish Cucumber Sauce

These elegant salmon and whitefish cakes offer a sophisticated twist on a classic seafood staple. By combining succulent salmon with mild whitefish and a medley of sautéed carrots and leeks, these patties achieve a balance of delicate sweetness and savoury depth. The addition of matzo meal ensures a light, firm texture that holds beautifully during frying, making them an excellent choice for those seeking a dairy-free alternative to traditional fish cakes.

Served alongside a cooling cucumber and horseradish sauce, this dish is perfect for a light spring lunch or as a refined starter for a dinner party.

These cakes can be prepared in advance and chilled, allowing the flavours to develop before a quick sear in the pan.
