Start by peeling your garlic cloves and adding them to a grinder or food processor. Toss in the whole egg, the extra yolk, mustard, sugar, salt, red wine vinegar, and Italian seasoning.

Grind or blend everything until the mixture is smooth and the sugar and salt are fully dissolved. This base should smell fragrant and slightly tangy from the vinegar and herbs.

Now comes the important part: adding the oil slowly. Pour in a little oil at a time while blending, letting the mixture thicken before adding more. This gradual process is what gives the dressing its creamy, emulsified texture.

Continue adding oil until you reach your desired consistency. I usually stop around ¾ cup for a thicker dressing, but you can go up to 1 cup if you want it a bit thinner.

Once done, transfer the dressing to a small bowl and let it rest for 5–10 minutes. This short wait allows the flavors to blend beautifully.
