Anchovy paste?

I am attempting to make my own caeser dressing. I am following a recipe from Better Homes and Gardens, one of my favorite cook books. However the recipe calls for 3 anchovies! Since we do not eat anchovies, I am replacing them with anchovy paste. I also do not have a mini blender or food processor ( I think I will be getting one soon). The.... concotion... is currently the color of mocha! I don't believe I have ever seen caeser dressing this color! I will keep you updated on the result tomorrow!
