What is the origin of cilantro, and how is it used in different cuisines?
Cilantro, also known as coriander, is an herb native to the Middle East and Mediterranean regions. It has been used for thousands of years in various cuisines, including Mexican, Indian, Chinese, and Thai cooking. The leaves and seeds of the plant are used in different ways, with the leaves typically used fresh or dried to add flavor to dishes like salsas, salads, and curries. The seeds, on the other hand, are often ground into a spice and used to add warmth and depth to stews, soups, and braises.
The use of cilantro varies significantly across different cultures, reflecting the diverse flavor profiles and cooking techniques of each region. In Mexican cuisine, cilantro is a staple herb used to add freshness and flavor to dishes like tacos, guacamole, and salsa. In Indian cuisine, cilantro is used to make chutneys, salads, and curries, where it is often combined with other herbs and spices to create complex flavor profiles. Similarly, in Chinese and Thai cooking, cilantro is used to add flavor to stir-fries, soups, and salads, where it is often paired with other aromatics like ginger and garlic.
Why do some people experience a soapy taste when eating cilantro, while others do not?
The phenomenon of experiencing a soapy taste when eating cilantro is a common complaint, with some people finding the herb to be unbearably unpleasant. Research suggests that this may be due to a genetic variation in the OR6A2 gene, which codes for an olfactory receptor that is responsible for detecting certain aldehyde chemicals. These chemicals are found in cilantro and are responsible for its distinctive flavor and aroma. People who have a certain variation of the OR6A2 gene may be more sensitive to these chemicals, which can result in the perception of a soapy or metallic taste.
The genetic basis of the soapy taste phenomenon is supported by studies that have shown that identical twins are more likely to share the same preference for cilantro than fraternal twins. This suggests that there is a strong genetic component to the perception of cilantro’s flavor, and that individual differences in taste perception may be influenced by genetic factors. Additionally, cultural and environmental factors may also play a role in shaping our preferences for cilantro, with people who are exposed to the herb from a young age being more likely to develop a taste for it.
How does the flavor of cilantro change when it is cooked or heated?
When cilantro is cooked or heated, its flavor and aroma undergo significant changes. The heat causes the volatile compounds in the herb to break down and evaporate, resulting in a milder and more subtle flavor. This is why cooked cilantro often tastes less pungent and soapy than fresh cilantro. Additionally, the heat can also bring out the natural sweetness in the herb, making it taste more balanced and complex. This is why cooked cilantro is often used in dishes like stews, braises, and curries, where it can add depth and warmth to the flavor profile.
The change in flavor when cilantro is cooked or heated is also due to the breakdown of the herb’s cell structure. When cilantro is fresh, its cells are intact, and the volatile compounds are trapped inside. However, when the herb is heated, the cells break down, and the compounds are released, resulting in a more muted flavor. This is why it is often recommended to add cilantro towards the end of cooking, so that its flavor and aroma can be preserved. By adding it at the end, the heat can still bring out the natural sweetness in the herb, but the flavor will not be lost due to overcooking.
