Question: what is the difference between ground thyme and dried thyme?
Answer: As a general rule, 1 teaspoon of dried herb is equal to 1/2 teaspoon of ground, according to The Reluctant Gourmet. So, do a bit of simple math: Since 1 teaspoon of dried herb equals 1/2 teaspoon of ground, replace the tablespoon of fresh thyme (from the previous example) with 1/2 teaspoon of ground.
