Hi nicklord1-I don't know what clams you're using, so you might want to consider finding out approximately how many clams are in a kilo and adjust your servings that way. What I dois this: I scrub the clams with a brush under running water to get rid of the snad on the shells. Then I leave them in water to I've added some flour. This gives the clams an internal cleansing. Next in a pot big enough to hold the clams, I'll heat some olive oil and saute chopped onion and garlic, Then I add white wine, boil for a minute, add the clams and cover the pot,shaking the pot every now and then.That way the clams steam with the onion, garlic and the wine. Then I check for clams that haven't opened, throw them away, and sprinkle the clams with chopped parsley and freshly ground black pepper. I have my spaghetti, boiled al dente and I mix it into the clams. Bon Appetit!!
