Understanding and Preparing Agathi Leaves
Agathi keerai, also known as Sesbania grandiflora or the vegetable hummingbird tree, is a fast-growing, soft-wooded tree native to Southeast Asia. Its leaves and flowers are valued for their high nutritional and medicinal properties, used extensively in both traditional cuisine and Ayurvedic medicine. With a slightly bitter, earthy taste and a crunchy, fibrous texture, these leaves are a nutritious addition to any meal when prepared correctly.
Before cooking, proper preparation is essential to ensure a pleasant culinary experience and remove any bitterness. Follow these simple steps:
- Harvest or Purchase Fresh Leaves: Choose fresh, tender leaves with a vibrant green color. Avoid any bunches with wilted or yellowing leaves.
- Strip the Leaves: Gently run your fingers along the stem to easily strip the leaflets. The small, tender stems can also be used, but the thicker ones should be discarded.
- Rinse Thoroughly: Wash the leaves multiple times in a large bowl of water to remove any dirt, sand, or debris. Rinsing in salted water is a traditional method to ensure they are fully clean.
- Blanch (Optional): For a milder flavor, some people blanch the leaves in boiling water for a minute or two before proceeding with their chosen recipe. This also helps soften the leaves and reduces bitterness.
- Chop: After draining, give the leaves a rough chop to prepare them for cooking.
Popular Agathi Leaf Recipes
Traditional South Indian Poriyal
Poriyal is a dry, stir-fried preparation and one of the most common ways to enjoy agathi keerai. This simple recipe brings out the leafy green's unique flavor while balancing its bitterness.
- Heat oil in a wok and add mustard seeds and urad dal. Let them splutter.
- Add dried red chilies, crushed garlic, and finely chopped onions. Sauté until the onions turn translucent.
- Add the washed and chopped agathi leaves. Stir-fry for a few minutes until they begin to wilt.
- Season with salt and a pinch of turmeric powder. Sprinkle some water, cover, and cook on low heat until the leaves are tender.
- Add freshly grated coconut and mix well for another minute before serving.
Flavorful Agathi Sambar
For a more substantial meal, agathi leaves can be cooked into a sambar, a lentil-based vegetable stew. This is a great way to incorporate the leaves into a comforting, nutritious dish.
- In a pressure cooker, combine two cups of cooked toor dal with a cup of agathi leaves, water, and turmeric.
- Cook until the leaves are tender.
- In a separate pan, prepare the sambar base with tamarind pulp, tomatoes, onions, and your preferred sambar spices.
- Mix the cooked agathi leaves and dal mixture into the sambar base. Simmer until the flavors are well combined.
Cooling Agathi Leaf Soup
Perfect for reducing body heat, a simple soup can be made by boiling agathi leaves with minimal spices. In traditional Siddha medicine, a soup of agathi spinach, small onion, pepper, and cumin is used to heal stomach ulcers.
- Boil chopped agathi leaves with small onions, a few peppercorns, and cumin seeds in water.
- Cook until the leaves are tender and the flavors have infused.
- Strain the liquid and serve the warm, nutrient-rich soup.
