Make the Anchovy Paste - On a cutting board, chop the anchovy fillets, minced garlic, and ¼ teaspoon salt together. Use the side of the knife to help scrape and mash into a paste.
Make the Caesar Dressing - In a medium bowl, whisk together the anchovy paste, egg yolk, lemon juice, zest, mustard, ½ teaspoon salt, and black pepper. Gradually whisk in olive oil until a thickened, smooth emulsion forms. Whisk in the parmesan cheese.
