Little toasts are one of my favorite nibbles to serve guests, and of all the many varieties I’ve put together over the years, this smoked salmon toast however is the one that gets gobbled with the most ferocity. People go crazy over smoked salmon! Of course, the appeal here goes beyond the fish—there’s also the cooling lemon crème fraîche, the sharp, tangy pickled onion, and the refreshingly crunchy cukes. The elements truly harmonize. On weekends when I suspect I’ll have friends around, I often make the components in advance so these toasts can be assembled in a pinch for an elegant, impromptu brunch.
