or the Tomato Tartar Sauce
In a small saucepan, bring the tomato sauce, wine, and garlic to a boil, stirring, over high. Reduce the heat to a simmer and reduce the mixture by half without stirring. Set aside to cool.
In the bowl of a food processor, combine the cooled reduction, mayonnaise, green onions, and gherkins. Process until smooth or desired consistency. Transfer the mixture to a bowl and stir in the parsley, hot sauce, and salt. Season to taste. Cover and refrigerate for at least an hour. Sauce can be made a day in advance.
