A question about a recipe: The (Not Barefoot) Contessa's Fish Pasta

I would suggest using dry white wine and the oil cured olives appear black.

Wine in a recipe with fish is usually to cut the fishy flavor and not so much to add sweetness. Dry white wine is probably better but if all you have on hand isn't terribly dry, taste afterwards and adjust the acidity as necessary, such as with some white wine vinegar or lemon juice.

The most common kind of oil-cured olive is black. They have a particular shriveled look to them, like big raisins.
