Ingredients:

  • 2 large cloves Garlic, peeled
  • 4-6 Anchovy Fillets, oil packed, drained
  • ½ tsp Kosher Salt
  • ½ tsp Black Pepper, freshly ground
  • 1 large Egg Yolk (pasteurised or very fresh)
  • 1 tsp Dijon Mustard
  • 2 Tbsp Fresh Lemon Juice
  • 1 tsp Worcestershire Sauce
  • ½ cup Light Olive Oil or Extra Virgin Olive Oil
  • ½ cup Neutral Oil (e.g., Canola, Grapeseed)
  • ½ cup Parmesan Cheese, finely grated
  • 2–4 Tbsp Ice Cold Water (for thinning)

Instructions:

  1. Prepare the Umami Paste: Finely mince the garlic cloves and the anchovy fillets. Combine the minced garlic, anchovies, salt, and pepper on the cutting board. Mash them together into a fine, smooth paste using the flat side of a knife or a mortar and pestle. Scrape the paste into the mixing bowl.
  2. Establish the Emulsion Base: Add the paste, the egg yolk, Dijon mustard, lemon juice, and Worcestershire sauce to the mixing bowl. Whisk vigorously for 30–60 seconds until the mixture is pale yellow, slightly foamy, and thoroughly combined. Ensure all these ingredients are at room temperature to aid emulsification.
  3. Drizzle and Emulsify (The Critical Phase): Combine the two oils in a small measuring jug with a spout. While whisking continuously and rapidly, introduce the oil one drop at a time for the first two minutes. Once the mixture thickens noticeably (it should resemble a thin mayonnaise), gradually increase the drizzle to a very thin, steady stream. Continue whisking until all the oil is incorporated and the dressing is thick, creamy, and pale yellow.
  4. Finish and Season: Fold in the finely grated Parmesan cheese using a spatula. Taste the dressing and adjust seasoning with salt, pepper, and potentially lemon juice. If the dressing is too thick, whisk in 1–2 tablespoons of ice-cold water to achieve the desired pouring consistency. Cover and refrigerate for a minimum of 30 minutes to allow the bold flavours to meld and deepen before serving.
