For homemade ketchup, combine 10 diced plum tomatoes, a third cup sugar, a quarter cup wine, one diced onion, and two teaspoons salt in a saucepan. Cook over a low heat until reduced and thickened. For paprika, slice a red pepper into strips. Roast in the oven at 190°F (90°C) for about two to three hours, or until dried out. Grind finely in a food processor or coffee grinder. (One pepper yields about three tablespoons paprika.)
