The sour and spicy flavor of Nellore-style fish curry is achieved by using tamarind pulp for sourness and a generous amount of red chili powder, along with a blend of spices like fenugreek seeds, mustard seeds, and curry leaves, for the spice.
Detailed Explanation:
Nellore-style fish curry is renowned for its bold and tangy taste. Here's how to recreate it:
- Tamarind Pulp: The primary souring agent is tamarind. Soak a lemon-sized ball of tamarind in warm water for about 30 minutes. Squeeze out the pulp and discard the seeds and fibers. The tamarind pulp provides the signature tang.
- Red Chili Powder: Use a high-quality, vibrant red chili powder. Nellore cuisine is known for its spiciness, so don't be shy with the chili powder. Adjust the quantity to your spice preference, but aim for a fiery kick.
- Spice Blend: A specific blend of spices is crucial. This typically includes:
- Fenugreek Seeds (Methi): Adds a slightly bitter and pungent note. Roast them lightly before grinding for enhanced flavor.
- Mustard Seeds (Rai): Provides a sharp, nutty flavor. They are usually tempered in oil until they splutter.
- Curry Leaves: Imparts a distinct aroma and flavor. Add them during tempering and also as a garnish.
- Other Spices: Turmeric powder (for color and health benefits), cumin seeds (for earthy flavor), and coriander powder (for body) are also commonly used.
- Tempering: Tempering the spices in oil is essential. Heat oil (mustard oil is preferred) and add mustard seeds. Once they splutter, add fenugreek seeds, cumin seeds, and curry leaves. This releases their flavors into the oil, which then infuses the entire curry.
- Cooking the Curry: Sauté onions until golden brown, then add ginger-garlic paste and sauté until the raw smell disappears. Add the spice powders (red chili, turmeric, coriander) and sauté briefly. Pour in the tamarind pulp and bring to a simmer. Add salt to taste. Gently add the fish pieces and cook until they are done, being careful not to overcook them.
Pro Tip:
Use firm, white-fleshed fish like seer fish (kingfish) or pomfret, as they hold their shape well during cooking and absorb the flavors beautifully. Avoid fish that flakes easily.
