Notes
Tips and Tricks
Tools - A food processor and a glass jar with a tight lid work well for this recipe.Use dry herbs - Dry the parsley and chives after washing them. Extra water can thin the vinaigrette and shorten its storage time.Use a mild olive oil - A strong or bitter olive oil can overpower the fresh herbs. Choose one with a mild taste.Taste after chilling - Cold temperatures can soften the taste of vinegar, salt, and herbs. Taste the vinaigrette after it chills and adjust the seasoning as needed.Let the oil warm slightly - Olive oil may become thick in the refrigerator. Let the jar rest at room temperature for several minutes before shaking.
Storing
Store in the Refrigerator - Keep the vinaigrette in a covered glass jar in the refrigerator for up to 5 days.Mix Before Serving - The oil and vinegar will separate while stored. Shake the covered jar or stir the vinaigrette before serving.Discard if Spoiled - Throw the dressing away if the herbs become slimy or if the vinaigrette develops an unusual smell.
