Tangy créme fraiche unites poached and smoked salmon in this quick and easy spread that's perfect for weekend brunch.
Bring 2 inches of water to a boil in a medium pot. Reduce heat to a simmer and season generously with salt. Add fresh salmon and poach until just cooked through, about 4 minutes. Remove with a slotted spoon and transfer to a plate. Let cool completely.
Combine creme fraiche, shallot, and chives in a medium bowl. Add poached and smoked salmon, gently stirring until just incorporated, with some flakes of fresh salmon remaining. Season with salt and pepper. Spread can be made 1 day ahead and stored in refrigerator. Before serving, top with chives and endive. Serve with crackers.
