from ButterYum
makes 1 1/4 cups
3/4 cup extra virgin olive oil (use really good quality)
1/2 cup red wine vinegar
1 teaspoon kosher salt
1 teaspoon ground black pepper
Combine ingredients together until homogenous. I like to mix and store my homemade dressings in this nifty dressing shaker, but a jar with a tight-fitting lid also works.
