Smoked Salmon Mousse Cups with Cucumber & Caviar

May 31, 2026
The smoked salmon mousse cup looks like something that requires a pastry team. It doesn't. Smoked salmon blended with cream cheese, lemon, dill, and horseradish — then lightened with folded whipped cream — produces a mousse of genuinely restaurant-quality texture and flavor that pipes beautifully and can be made 24 hours ahead.
The folded cream is the step that creates the lightness; don't skip it and don't overmix once it's in. Piped into cucumber cups or small glasses, topped with a curl of salmon roe and a dill frond — it's the bite that makes people ask how you made it.
Ingredients (makes 24 cups):
For the Cups: - Option A: 4 large English cucumbers, cut into 1-inch cylinders, centers scooped to form cups - Option B: 24 small shot glasses, spoons, or endive leaves for a more elegant, modern presentation
Smoked Salmon Mousse: - 9 oz cold-smoked salmon, roughly chopped - 5 oz full-fat cream cheese, softened - ⅔ cup heavy cream (cold) - 2 tablespoons fresh lemon juice + zest of 1 lemon - 1 tablespoon fresh dill, finely minced - 1 tablespoon fresh chives, minced - 1 teaspoon fresh horseradish (grated) or ½ teaspoon prepared - 1 teaspoon capers, finely minced - Salt and white pepper
Garnish: - 2 ⅞ oz salmon roe, trout caviar, or good-quality black lumpfish roe - Cucumber ribbons (peeled with a vegetable peeler into thin strips) - Fresh dill fronds - Lemon zest - Flaky sea salt - Microgreens
Mousse Instructions: Process smoked salmon and cream cheese in a food processor until very smooth, scraping down the sides. Add lemon juice, lemon zest, dill, chives, horseradish, capers, salt, and white pepper. Process until combined and smooth. Taste — the mousse should be bright, smoky, and well-seasoned.
In a separate chilled bowl, whip the cold heavy cream to soft peaks. Using a spatula, fold the cream into the salmon mixture in two additions — work gently to maintain the airiness. Taste for seasoning. Transfer to a piping bag fitted with a large round or star tip. Refrigerate up to 24 hours.
Cucumber Cups: Slice cucumbers into 1-inch-thick rounds. Use a small melon baller or ½ teaspoon to scoop out a well in the center of each round, leaving the base intact. Pat completely dry.
Assembly: Pipe a generous swirl of smoked salmon mousse into each cucumber cup or serving glass. Twist a thin strip of cucumber ribbon into a small curl and place on top of the mousse. Add a small spoonful of salmon roe or caviar (about ½ teaspoon). Place a small dill frond. Finish with a pinch of lemon zest and a grain of flaky salt.
Arrange on a chilled platter. Serve immediately or refrigerate for up to 1 hour.
The Mimosa Pairing Logic: Smoked salmon and Champagne is one of the most widely known pairing combinations in fine dining — the salmon's richness and smokiness are perfectly complemented by the wine's acidity and effervescence. These cups are designed specifically to amplify a classic orange mimosa, blood orange mimosa, or grapefruit mimosa — the citrus in the drink echoes the lemon in the mousse and brightens the salmon's flavor.
Pro Tips: The folded whipped cream is what creates the mousse's lightness — do not skip this step or process the cream directly into the salmon. Over-mixing after folding deflates the mousse and produces a dense, heavy result. For maximum impact, chill the serving platter in the freezer for 30 minutes before plating.
