To poach salmon: In a deep skillet, place salmon skin side down. Pour enough liquid (white wine is good, but water works, too) to cover the salmon. Bring to a simmer, but do not boil. Poach for 5 to 10 minutes or until the flesh is opaque. Remove salmon from liquid, then remove skin. Cool.
To prepare rillettes: Crush the poached salmon with a fork. Mix in the smoked salmon, egg yolk, softened butter, salt and pepper.
Line two small loaf pans (41/2 by 21/2) with foil, pack the mixture in, cover with plastic wrap and refrigerate for at least an hour.
Slice and serve on farmhouse bread or small slices of a baguette, accompanied by rosé Champagne.
