This seems like a very odd combination, but your guests will be amazed, and you shouldn't be surprised when asked for the recipe. The salad is rare delicious on a hot summer day and ideal to serve while waiting for the meat on the barbecue to be ready. You can use self-smoked fish for this salad, but given the small amount, packets from the fishmonger or supermarket are recommended. Instead of trout, you can take smoked herring, halibut, or mackerel (or a mix of these if you need to multiply the recipe. The salmon contrasts nicely in color, so it is best to keep it in proportion (50%).
