For garnish, capers, sliced black olives & parsley
Cook oil, butter, flour and chicken broth until it thickens. Add garlic, artichoke hearts (chopped), lemon juice and cheese. Continue cooking until flavors blend - about five minutes. Add capers and parsley. Top the pasta dishes with small, sliced black olives.
To cook the Linguini: Bring six quarts of water to a boil in a large pot. Add one tablespoon olive oil and two teaspoons of salt. Add the linguini and keep boiling until tender but firm (al dente), 8 to 10 minutes. Drain pasta and immediately toss with artichoke sauce. Sprinkle each dish with small, black, sliced olives.
