Then add: Pepper, Garlic, Lemon zest, Dijon, Dill, Parsley, and Cayenne. Mix briefly.
10 Add the egg white, followed gradually by the cold cream and finally the lemon juice.
11 Mix just until everything is incorporated and the sausage becomes tacky enough that some mixture sticks to your inverted palm.
12 Keep the mixture below about 40°F throughout.
4. Fry a test patty
13 Definitely do this before stuffing. Cook a tablespoon in a skillet and check: Salt, Lemon, Dill, Pepper, and Texture The flavor should be relatively delicate. I'd resist the temptation to pile on seasoning because salmon and shrimp are doing most of the work.
5. Stuff
14 Stuff fairly loosely into the casings. Make links about 5 inches long. Then refrigerate uncovered for an hour or two before cooking. That gives the casing a chance to dry slightly and the sausage mixture time to firm.
6. Cooking
15 These would be excellent poached and then grilled, particularly for the stream.
16 Bring water to around 170°F / 77°C—not a boil.
17 Poach the links gently until the centers reach about 135–140°F.
18 Remove and dry thoroughly.
19 Then finish quickly on a moderately hot grill or skillet to brown the casings, taking them to 145°F internally.
20 That gives you much better control than trying to grill the raw seafood links from beginning to end.
