When substituting ground thyme for rubbed thyme, use a 1:1 ratio; however, ground thyme is more concentrated in flavor, so you may want to start with slightly less. Typically, about 1 teaspoon of ground thyme can replace 1 teaspoon of rubbed thyme. Adjust according to your taste preference, as the potency can vary.
With thyme one fresh sprig equals one-half teaspoon of dried thyme. In general, use two to three times the amount of fresh thyme as dried. When adding to soups and stews, crush the leaves between your hands before stirring it in your recipe.
A sprig is a single stem snipped from the plant. It is composed of a woody stem with paired leaf or flower clusters ("leaves") spaced ½ to 1" apart.
Generally, one sprig of fresh thyme is equivalent to about 1/3 teaspoon of dried thyme. Therefore, 12 sprigs would equal approximately 4 teaspoons of dried thyme. If you prefer to measure in tablespoons, that would be about 1 tablespoon plus 1 teaspoon of dried thyme. Keep in mind that dried herbs are more concentrated in flavor than fresh ones, so adjust to taste if needed.
