When a recipe calls for a “sprig” of a fresh herb like thyme, rosemary, or mint, how much is that? While there isn’t a truly clear-cut answer, you can follow this guideline. Unless the recipe specifies otherwise, I think of a sprig as a single stem of a fresh herb about 4 inches long. But if the herbs I’m working with seem to be unusually sparse or bodacious, I’ll use a little more or less accordingly.
Rub dried herbs between the palms of your hands before using them. This crushing action helps release their flavor.
