This is my go-to salad dressing. I never get tired of it. It works with practically any kind of salad including with fruits, unless it’s a ‘classic’ salad which requires a special dressing, such as Caesar, Caprese, Greek, etc.
Be sure to use a high quality champagne vinegar. It’s the Wild West out there regarding being able to use the term “champagne” when it comes to making vinegars.
Mustard is used as a surfactant to keep your emulsified dressing in suspension. That means the oil and vinegar will take much longer to separate.
EQUIPMENT: jar with a tight seal such as a canning jar
