I have a weakness for smoked fish for breakfast. I don't know if it comes from my Cornish ancestors, but a plate of fine kippers, toast, and tea has always seemed a morning treat. The last time I had truly great kippers was in 2010, visiting a friend who lives in Eastbourne, in England. Here in Northern California, while we can get excellent, local smoked salmon, kippers are hard to come by. However, I do get smoked sturgeon occasionally, which, sautéed in a touch of olive oil, can be delicious, but sturgeon tends to be dry. I recently looked up a recipe for a sauce for smoked fish that I tried today for the first time, thinking it might be a good way to counteract the dryness of the sturgeon.
While I'd never ruin a good kipper with a sauce, and I think this recipe might be even better on an oilier fish than sturgeon (like smoked salmon), it turned out quite nicely. I finely minced equal parts of red onion and capers, and then added about half as much fresh horseradish, a few teaspoons of sherry vinegar (the recipe calls for red wine vinegar, but sherry vinegar is what I had in the house), and a couple of tablespoons of mayonnaise. I was too lazy to pick a few leaves of parsley from the garden, but a little green would have been a nice touch. These ingredients all mixed together made a nice topping for my smoked sturgeon this morning. I can see this being good on almost any fish dish. Give it a try.
