1 1/2 cups olive oil
1 tablespoon red wine vinegar
1/4 cup lemon juice
1 tablespoon Worcestershire sauce
2 tablespoons anchovy paste
1/2 teaspoon mustard powder
4 cloves garlic, crushed
3 tablespoons sour cream
1/2 cup grated Parmesan cheese

In a food processor or blender, combine the olive oil, vinegar, lemon juice, Worcestershire sauce, anchovy paste, mustard, garlic, sour cream and Parmesan cheese. Process until smooth. Pour into a glass container, seal, and refrigerate until ready to use.

dmv notes: very tasty, I cut the recipe in half using 2/3 c. olive oil and less parm.
