This Gobi Manchurian is packed with texture and flavor. It combines crispy, double-fried battered cauliflower with a spicy, tangy sauce. It's no surprise that this Indo-Chinese classic, also known as Chindian cuisine, is one of the most popular Indo-Chinese recipes in the world.
In a large bowl, combine the cornstarch, all-purpose flour, salt, Kashmiri red chili powder, and pepper. Gradually mix in enough water to form a thick but runny batter. Add the cauliflower florets and toss until well coated.
Fry the Cauliflower:
Heat oil in a large pot between 160°C and 170°C (320°F and 340°F). Deep fry the battered cauliflower in batches for about 3 minutes or until cooked through. Remove from the oil and drain on a wire rack. Increase the oil temperature to 180°C (355°F) and fry the cauliflower again in batches until golden brown and crispy. Remove and drain again.
Make the Sauce:
In a large deep sauté pan or karahi, heat 2 tablespoons of oil over medium heat. Add red onion, garlic, ginger, green chili, and the white parts of the spring onion. Season with salt, MSG (if using), and white pepper. Stir fry until the garlic is soft.
Add the capsicum and continue to stir fry for 2 minutes. Stir in the soy sauce, red chili sauce, tomato ketchup, and water. Simmer for 3-4 minutes.
Thicken the Sauce:
Prepare a cornstarch slurry by mixing 1 teaspoon cornstarch with 1 tablespoon water. Add to the sauce and simmer for 1 minute, or until the sauce thickens.
Combine and Serve:
Add the fried cauliflower to the sauce, toss to coat, and cook until hot. Garnish with the green parts of the spring onion. Serve immediately.
