Begin by pouring enough salted water into a medium saucepan to fill it two inches deep, then bring the water to a gentle simmer over medium heat. Carefully place the fresh salmon fillet into the water and poach it for 5-8 minutes until it turns opaque and flakes easily with a fork. Once cooked, remove the salmon from the water and set it aside to cool down.

While the salmon cools, finely mince one shallot and a handful of fresh chives to add bright flavor to your salmon rillettes. Then, cut a lemon in half and juice it, ensuring to catch any seeds. This is an excellent time to gather all your prepped ingredients together, so everything is within reach for mixing later.

Once the salmon is cool enough to handle, flake it into a large mixing bowl using a fork. Add the softened butter and mayonnaise to the flaked salmon and combine them until you achieve a creamy consistency. Then, fold in the minced shallots, chives, and freshly squeezed lemon juice. Season with kosher salt and pepper, adjusting to your taste for that perfect flavor balance in your salmon rillettes.

Transfer your luscious salmon rillettes to a charming serving bowl or a decorative jar. For the best flavor experience, let it sit at room temperature for about an hour before serving, which allows the flavors to meld beautifully. If you’re not serving right away, cover it tightly and refrigerate, taking it out 30 minutes before serving to soften. Pair your rillettes with sliced baguette and enjoy this elegant appetizer!
