My favorite herb is Parsley!

Explanation:

When using Parsley fresh, I recommend removing the bitter stem from the plant only if you are garnishing a dish. When cooking with this herb, the bitter stem can distract from the light flavor of the herb itself, and when topping a dish for presentation (or flavor) only using the leaves are recommended! This ensures you achieve the undertone flavor and scent of the herb, while not overpowering the dish itself.

When using fresh parsley, the stem should be used if you are combining the herb into the dish. The stem can compliment the rest of a dish when baked, and especially in breads. When using parsley in a bread or other doughy food, the bitterness of the stem and the light flavor of the leaves create a pleasant break in flavor, and turn a mediocre bread to a fantastic one!

when using the herb dried, its just perfect for dressing up pasta dished as a garnish, while still adding to the overall flavor of the meal. In summery, Parsley is a versatile herb when dried or fresh, you just have to know when to keep the stem and when to put it aside.

Hope this helps! good luck on your test :)
