Here's my basic salad dressing recipe. You will never buy that bizarre-o stuff in a bottle again and it takes seconds to make:
Simple Balsamic Vinaigrette
2 Tbs. white balsamic vinegar
1/4 cup extra virgin olive oil
1 garlic clove, finely grated or chopped
1 tsp. dijon mustard
salt and pepper
In a small bowl, whisk together the vinegar, garlic, mustard, salt and pepper. While whisking, Slowly add in the olive oil in a stream. The mustard will act as an emulsifier and will keep the vinaigrette from separating. Taste for seasoning and enjoy.
