Mince and mash garlic cloves to a paste with a pinch of salt using a large heavy knife.
2 garlic cloves
Whisk together 1 yolk, 2 teaspoons lemon juice, and ½ teaspoon mustard in a bowl.
1 large egg yolk, 2 teaspoons fresh lemon juice, ½ teaspoon Dijon mustard
Combine ¼ cup EVOO, 3 Tablespoons vegetable oil (if using), and add slowly to yolk mixture, whisking constantly, until all oil is incorporated and mixture is emulsified. (If mixture separates, stop adding oil and continue whisking until mixture comes together, then resume adding oil.)
¼ cup extra-virgin olive oil, 3 Tablespoons vegetable oil,
Whisk in garlic paste and 12 kalamata olives. Season with more salt, if needed (remember the kalamata olives are pretty salty-tasting. Add fresh ground black pepper, if desired).
12 pitted kalamata olives,
Chill, covered, until ready to use. May be stored in the refrigerator as long as the use-by date on the carton from the egg yolk you used.
Serve with homemade fries, pretzels or pretzel chips, burgers, chicken, or steamed artichokes.
