Herbs(rau thơm) are a very significant part of Vietnamese cuisine. They are appreciated for their medicinal qualities as well as the diverse flavors and aromas they provide. Large quantities of herbs are typically serves at each Vietnamese meal. In Vietnamese culture, herbs are considered cooling, or yin, and help counter warming elements, or yang, for a balanced and satisfying meal.
Leafy vegetables are often known as rau in Vietnamese, though the word rau is often omitted when referring to most herbs; for example, rau tiá tô is usually just called tiá tô. The word thơm means fragrant or aromatic. Rau thơm is a general term for herbs.
Herbs are both easy to use and easy to grow. I recommend growing your own herbs for greater mindfulness and appreciation of your meal as well as convenience and freshness. Most herbs are eaten raw in salads or added as garnish.
Some of the most important herbs in Vietnamese cuisine are outlined below. Many have similar uses and can replace familiar herbs in a dish for a new twist. Many of these herbs can also be combined into a salad called rau sống to accompany just about any dish.
