In a lidded container, prepare the sauce by mixing all ingredients well. Close the lid and let the flavors blend.
In a bowl, combine the salmon with the sauce, mix well, and set aside for a few minutes to allow the flavors to develop.
Cut the avocado in half, remove the pit, and scoop out the flesh. Mash it into a smooth cream, season with a little salt, and mix well.
Place a round mold (ring) in the center of a plate. Add a layer of mashed avocado at the bottom, then fill the mold to the top with the salmon mixture, pressing gently with a spoon to smooth the surface.
Refrigerate for 7-8 minutes to help it set.
Carefully remove the mold, sprinkle with chopped chives, and serve.
Make sure that before preparing your tartare, all ingredients are chilled. This ensures the dish stays fresh and enhances the overall texture and flavor. Enjoy!
