Parsley is one of the most commonly used leaf spices in western cooking, as it has a pleasant light, fresh aroma, and blends very well with most other spices, savory or earthy. It works well both hot or cold, and complements meats, cheeses, vegetables, beans, or grains equally well. Parsley is easy to use and often unlocks aromas and flavors of other ingredients very well.
Protip: dry parsley can be used in most recipes as a substitute for fresh parsley at a ratio of 3 for 1 – i.e., if the recipe calls for 3 tsp of fresh parsley, use 1 tsp of dry. Add parsley as close to the end of your cooking as possible (2-3 minutes before serving is ideal), so it does not burn or become lifeless from overcooking!
