Most recipes calling for herbs cite a volume amount. But this measurement is not helpful at the supermarket when you’re faced with herbs tied into bunches or stuffed into plastic clamshells.
To make shopping easier, we bought multiple bunches and clamshells of 12 commonly used herbs, chopped or minced them according to the prep method we use most often for each type, and measured the yield to determine a weight-to-volume equivalency.
The yields below are an average volume for the weight cited. Keep in mind that the yield can vary, particularly with woody herbs such as rosemary and thyme, and clamshells don’t always deliver on the promised amount (for example, we discovered that many ¾ ounce packages contained only ⅝ ounce of herbs).
