Creamy Mustard Vinaigrette
Ina Garten, Barefoot Contessa

3 tablespoons Champagne vinegar
1/2 teaspoon Dijon mustard
1/2 teaspoon minced fresh garlic
1 extra-large egg yolk*, at room temperature (see Note)
3/4 teaspoon kosher salt
1/4 teaspoon freshly ground black pepper
1/2 cup good olive oil
Salad greens or mesclun mix for 6 to 8 people

In a small bowl, whisk together the vinegar, mustard, garlic, egg yolk, salt, and pepper. While whisking, slowly add the olive oil until the vinaigrette is emulsified. Toss the greens with enough dressing to moisten and serve immediately.

Note: If you're worried about raw egg, just omit it.
