Create a flour well on a clean work surface. Crack eggs into the well, add squid ink and salt.
Gradually incorporate flour with a fork, then knead for 8-10 minutes until smooth and elastic.
Wrap dough and let rest at room temperature for 30 minutes.
Divide dough into 4 portions. Flatten and roll through a pasta machine, gradually reducing thickness.
Cut pasta into linguine or spaghetti, dust with flour, and form into nests.
Heat olive oil in a skillet, add garlic and red pepper flakes, cook until fragrant.
Add seafood, cook until just opaque (3-4 minutes), season with salt and black pepper.
Boil salted water, cook pasta for 2-3 minutes until al dente. Reserve pasta water.
Toss pasta with seafood sauce, adding pasta water if needed for a silky texture.
Garnish with fresh parsley and a squeeze of lemon juice.
