Step 1Heat large skillet over medium-high heat and add oil. When oil is hot, add shallots and cook until softened and aromatic, about 2 to 3 minutes. Add garlic and stir 20 seconds. Add wine and bring to boil. Reduce heat to low, add cockles, cover and simmer.
Step 2Meanwhile, add linguine to boiling salted water.
Step 3Check cockles after 1 to 2 minutes to see if any have opened; if so, remove them to covered plate. Cover skillet and continue cooking until all cockles have opened. Discard any that do not open. Return cockles to skillet.
Step 4Cook pasta until al dente, about 10 minutes, drain quickly and place in serving bowl. Pour cockles and sauce from skillet on top, sprinkle with parsley, then serve.
