Ingredients
For the Mousse
- 8 oz hot-smoked salmon skin removed, at room temperature
- 6 oz cream cheese softened to room temperature
- 1/3 cup heavy cream cold
- 2 tbsp fresh lemon juice
- 1 tbsp fresh dill finely minced, plus more for garnish
- 1 tsp prepared horseradish drained
- 1/4 tsp white pepper freshly ground
- 1/8 tsp cayenne pepper
For Assembly
- 2 large English cucumbers about 14 inches each
- 1/2 tsp flaky sea salt for finishing
- 24 small fresh dill fronds for garnish
- 1 tbsp capers drained and patted dry, optional
Instructions
Prepare the Mousse Base
- Place the smoked salmon in a food processor and pulse 8-10 times until broken into small pieces. Add the softened cream cheese and process for 30 seconds until the mixture is smooth with no visible salmon chunks.
- Add the lemon juice, minced dill, horseradish, white pepper, and cayenne. Process for another 15 seconds until fully incorporated. Scrape down the sides of the bowl with a rubber spatula.
- With the processor running on low, slowly drizzle in the cold heavy cream through the feed tube. Process just until the mixture becomes light and fluffy, about 20 seconds. Do not over-process or the cream may begin to separate.
- Taste and adjust seasoning. The mousse should have a pronounced salmon flavor balanced by bright acidity and gentle heat. Transfer to a bowl, press plastic wrap directly onto the surface, and refrigerate for at least 1 hour to allow flavors to meld and the mousse to firm.
Prepare the Cucumber Rounds
- Wash and dry the English cucumbers. Using a sharp knife or mandoline, slice into rounds approximately 1/4-inch thick. You should get about 12-14 slices per cucumber.
- Arrange the cucumber slices in a single layer on paper towels. Blot the tops gently with additional paper towels to remove excess surface moisture. This step prevents the mousse from sliding and keeps the appetizers crisp.
Assemble and Garnish
- Transfer the chilled mousse to a piping bag fitted with a large star tip (such as Ateco 826 or Wilton 1M). If you don't have a piping bag, use a zip-top bag with one corner snipped off.
- Pipe a generous rosette of mousse onto each cucumber round, starting from the center and spiraling outward. Each portion should be approximately 1 tablespoon.
- Finish each piece with a small dill frond, a few flakes of sea salt, and if desired, a single caper. Serve immediately or refrigerate uncovered for up to 2 hours before serving.
Notes
For best results, ensure cream cheese reaches true room temperature (68-70°F) before processing. Cold cream cheese creates a grainy texture.
Hot-smoked salmon produces a richer, more pronounced flavor than cold-smoked (lox). If using cold-smoked salmon, reduce the lemon juice to 1 tablespoon to prevent overwhelming the delicate fish.
The mousse can be prepared up to 2 days ahead. Bring to cool room temperature for 15 minutes before piping for easiest handling.
For cocktail parties, prepare cucumber rounds and pipe mousse up to 2 hours ahead. Add garnishes just before serving to maintain their fresh appearance.
