Thai cuisine, revered worldwide for its aromatic flavors, owes a significant part of its charm to the humble basil. However, not just any basil, but three distinctive types that each bring a unique twist to the table. Thai basil, Holy basil, and Lemon basil, each with their own distinctive flavors that give Thai food its distinctive character.
Thai basil, with its sweet anise-like scent and hint of licorice, is the most commonly used variety in Southeast Asia and Western kitchens. Holy basil, on the other hand, is a favorite among the Thai people for its spicy, peppery, clove-like taste. Lastly, Lemon basil, as its name suggests, brings a refreshing hint of lemon to dishes. Dive in, as we explore the fascinating world of this herb and its role in transforming everyday meals into culinary delights.
Understanding Thai Basil
At the heart of Thai cuisine, we find an unassuming, yet powerful player: Thai Basil, or Ocimum basilicum.
Aromatic Characteristics
Thai basil is a remarkable herb. This intriguing scent results from its rich content of essential oils, lending a unique aromatic identity. There’s an undercurrent of a slight spiciness in this herb that surprisingly is absent in its cousin, sweet basil. It’s the intricate amalgamation of these scents that makes Thai basil top tier in the culinary world.
Essential oils, packed with aromatic compounds, primarily fuel Ocimum basilicum‘s notorious aroma. Among these compounds, eugenol emerges as a distinctive contributor, with bonus potential health benefits like facilitating relaxation in blood vessels thereby, lowering blood pressure.
Cultivar-dependent Volatile Composition
What really shapes its aroma profile? It’s all down to its volatile composition. Its aromatic profile includes compounds such as linalool, estragole, and methyl chavicol. What’s intriguing is that the concentration of these compounds varies across different cultivars of Thai basil, adding diversity to its scent and flavor.
Physical Characteristics
Thai basil stands compact and sturdy, with shiny, slightly serrated, and narrow green leaves. It garners attention with its purple stem which, much like other plants in the mint family, assumes a square form. The leaves grow in an opposite and decussate manner. This herb blooms in the form of a thryse, presenting a purple inflorescence and pink flowers upon opening. Clocking in at a maximum height of 45cm (1ft 6in), it’s small but never overlooked.
So, let’s admire how this humble herb plays such instrumental roles, all the way from being an aromatic powerhouse to offering potential health benefits. Thai basil sure does capture the essence of subtlety and complexity in an exquisitely balanced manner.
Culinary Uses of Thai Basil
Thai Basil, appreciated for its unique anise or black licorice flavor, takes center stage in multiple Southeast Asian dishes. The versatility of Ocimum basilicum is seen across a variety of dishes, enhancing flavor profiles and adding an aromatic punch.
Stir-Fries and Sautes
In stir-fry recipes, Ocimum basilicum often steals the show. Specifically, the Thai Basil Shrimp Stir Fry, which comes alive with the combination of Thai basil, garlic, ginger, and soy sauce, exhibits the herb’s potent punch. Its robust presence enhances the dish’s overall flavor, making it a beloved choice for stir-fry dishes far and wide.
Curries and Soups
Thai basil’s role isn’t just limited to stir-fries. It’s a fundamental element in Thai and Vietnamese curries, where it adds complexity and depth of flavor to the dishes. The iconic Vietnamese dish, Pho, employs Thai basil as a garnish to lend its characteristic aromatic flavor.
Fried Rice
Fried rice dishes benefit from the addition of Thai basil. This unique flavor component, with its herbaceous and subtly spicy undertones, makes fried rice dishes more aromatic, boosting their appeal.
Spring Rolls and Noodle Bowls
Pairing Thai basil with other fresh ingredients, such as carrots, lettuce, and green onions in fresh spring rolls and noodle bowls, balances the anise flavor of the herb. This careful blending of flavors showcases the dynamic and transformative effect of Thai basil in Southeast Asian cuisine.
Substituting Thai Basil with Other Varieties
Thai basil’s unique flavor profile can be challenging to replicate exactly, but alternatives do exist. Let’s discuss how sweet basil and holy basil compare and can sometimes substitute Ocimum basilicum.
Difference between Thai Basil and Sweet Basil
Thai Basil and Sweet Basil, both varieties of Ocimum basilicum, show noticeable differences. Known as the most commonly utilized basil type, Sweet Basil swaps in for Thai basil in many recipes, delivering a satisfactory outcome. It’s important, though, to comprehend the inherent differences. This herb boasts an anise-like, slightly spicy flavor constituting its signature flavor profile. Sweet basil, on the other hand, lacks that distinct characteristic. Instead, it brings a smoother, sweetly perfumed character to dishes, absent the spiciness inherent to Thai basil.
Renowned chef Khaengkarn suggested supplementing sweet basil with mint is a viable solution to reconcile this lack of spicy underbite. However, striking a balance with sweet basil might necessitate alterations to a recipe, such as reducing sugar or increasing the salt or spice content.
The Role of Holy Basil
Another basil variety, Holy Basil (Ocimum tenuiflorum), offers a completely different flavor profile. Often found in Ayurvedic and folk medicine, holy basil possesses a stronger, more medicinal taste compared to Thai basil, centered around intense notes of pepper and clove. While its flavor remains distinct and more intense, using holy basil as a direct substitute for this herb in culinary dishes isn’t typical. It’s limited accessibility in the US has led to many chefs opting for Thai basil as a closer alternative in flavor and aroma.
So, while each basil variety retains its unique bouquet, finding a precise match for Thai basil may prove difficult. Nonetheless, creative use of sweet and holy basil might just provide a surprising substitute in your culinary adventures.
Growing and Buying Thai Basil
Navigating the journey of nurturing Thai basil from seed to a flourishing green plant or finding the freshest leaves in your local market, can be quite an adventure. Let’s delve into the practical aspects of acquiring and growing this extraordinary herb.
Finding and Buying Thai Basil
Thai basil, with its sweet anise intensity, makes a significant impact on numerous Southeast Asian dishes. Its distinct flavor profile is often desired in Thai curries or a Taiwanese three cup chicken. Yet, for the adventurous cook residing in cities with a Southeast Asian population, sourcing fresh Ocimum basilicum might be simpler than expected. Specialty groceries catering to these communities often stock Thai basil.
Simultaneously, due to the rising popularity and demand for this herb, some farmers in these cities are now cultivating Thai basil and selling it at local farmers’ markets. Additionally, its availability online means it’s within reach of anyone. To ensure you get the best, keep an eye out for Thai basil leaves characterized by a bright color and lively, non-droopy demeanor.
Tips for Growing Thai Basil
Thai basil, a tender perennial hardy in USDA plant hardiness zone 10, can be grown from seeds or cuttings. For growers based in regions with a more temperate climate, it’s traditionally grown as an annual due to its susceptibility to frost.
When considering planting Thai basil, initiating seed germination inside about six weeks before the final frost date in the spring is advisable. After which, transplanting the seedlings outdoors is best done late in the spring, ensuring soil temperatures are consistently around 70 degrees, and night temperatures remain above 50 degrees.
On the other hand, you can sow seeds directly outdoors when the risk of frost has completely subsided. Seeds should be about one-quarter of an inch in the ground and 12 inches apart, ensuring seedlings have enough room to develop and air can circulate freely.
Remember, Thai basil thrives in fertile, well-draining soil with a pH ranging from 6.5 to 7.5. To enrich the soil, consider incorporating organic compost. Also, an ideal environment offers 6 to 8 hours of full sunlight each day.
Watering is another crucial aspect of growing Thai basil. Keep the soil moist, particularly during rainless periods. Water thoroughly but avoid over-saturating by ensuring the top 1-2 inches of soil have dried before watering again.
