Ingredients:
- 1 large egg yolk
- 2 cloves garlic, minced
- 1 teaspoon Dijon mustard
- 1 tablespoon lemon juice, freshly squeezed
- 1/2 teaspoon Worcestershire sauce
- 1/4 cup grated Parmesan cheese, finely grated
- 1/2 cup extra virgin olive oil
- 2 tablespoons vegetable oil
- Salt and freshly ground black pepper to taste
- Optional: 1-2 anchovy fillets, finely minced
Instructions:
- In a medium mixing bowl, whisk together the egg yolk, minced garlic, Dijon mustard, lemon juice, and Worcestershire sauce until combined.
- Whisk in the grated Parmesan cheese.
- Gradually drizzle in the olive oil very slowly while whisking constantly. This is crucial for a smooth emulsion. Continue drizzling slowly until the dressing begins to thicken.
- Slowly drizzle in the vegetable oil, whisking continuously until the dressing is fully emulsified and smooth.
- Season with salt and freshly ground black pepper to taste. Add minced anchovy (or anchovy paste) if using.
- Cover the bowl and refrigerate for at least 30 minutes to allow the flavors to meld (optional).
