Step 1: Add the 1/3 cup milk, anchovies, garlic, 2/3 of the cilantro + the pepper to a blender & pulse to combine. W/the motor running, pour the oil in what the Portuguese call a "fio" (or fine thread). Keep whirring until the oil is incorporated & the mixture thickens (30 sec to 1 1/2 min depending on the equipment).
Step 2: Scrape the dip into a serving bowl & stir in the olives. Mince the remaining cilantro, sprinkle on top & serve. If the dip thickens more than desired, stir in 1-2 tbsp of milk.
