Pick your pasta shape: Any type of pasta works; spaghetti, linguine, shells.
Salt your pasta water: It should taste like the sea. This is your only chance to season the pasta itself.
Use fresh or quality cooked crab: Dungeness is ideal, but whatever you use, make sure it’s sweet, fresh, and fully picked through.
Toast the pine nuts: A few minutes in a dry pan brings out their nutty flavor and adds welcome crunch.
Rinse the capers: A quick rinse removes excess brine so they add pop, not punch.
Taste before serving: With lemon, capers, and Old Bay, seasoning can build quickly. You may not need any additional salt.
Use heavy cream, not half-and-half: The higher fat content holds up better to lemon and heat, so the sauce stays smooth instead of splitting.
