This is my very favorite salad vinaigrette. The recipe is from The Barefoot Contessa and yes, it has a raw egg in it. If you are worried about it just use a organic farm fresh egg or omit it. Personally, I think it adds such a creamy consistency to this dressing that I can't imagine the recipe without it!
1/2 teaspoon Dijon mustard
1 egg yolk, at room temp
1/2 teaspoon minced garlic
3 tablespoons champagne or white wine vinegar
salt & pepper to taste
1/2 cup olive oil
Whisk together first 5 ingredients, then slowly whisk in olive oil until emulsified.
Sometimes I like to add a little lemon too, if I'm feeling saucy!
