Preparation:
Place the zest, juice, mustard, garlic, egg yolks, pepper, salt, and bread in a blender or food processor and puree to a smooth paste.
With the machine running, drizzle in the oil. If the aioli appears too thick, add 2 tablespoons of water at a time to adjust the consistency. Store in an airtight jar in the refrigerator for up to 2 weeks. |
