Nethili Thokku Recipe – Spicy Anchovy Pickle the Tamil Way

Nethili Thokku is one of the most beloved condiments in Tamil Nadu — a fiery, tangy anchovy pickle that pairs perfectly with curd rice, idli, dosa, or plain steamed rice. Made with dried Nethili (anchovies), this thokku is a flavour bomb that keeps well for weeks. Here’s the authentic recipe.

What is Nethili Thokku?

Thokku is a thick, oil-based pickle or chutney from Tamil Nadu cuisine. Unlike fresh chutneys, thokku is cooked down with oil and spices to create a shelf-stable, intensely flavoured condiment. Nethili Thokku uses dried anchovies as the base, giving it a deep umami richness that is uniquely coastal.

Ingredients

• 200g dried Nethili (anchovies) – cleaned and rinsed
• 20–25 dry red chillies (adjust to taste)
• 1 large onion, roughly chopped
• 10 garlic cloves
• 1 tsp tamarind paste (or small gooseberry-sized tamarind soaked in water)
• 1 tsp mustard seeds
• 1 sprig curry leaves
• ½ tsp turmeric powder
• 1 tsp fennel seeds
• Salt to taste
• 5–6 tbsp sesame oil (nallennai)

Method

1. Prep the anchovies: Rinse the dried Nethili 2–3 times in cold water. Drain and set aside.
2. Dry roast: In a dry pan, lightly roast the red chillies and fennel seeds for 1–2 minutes until fragrant. Cool and grind to a coarse powder.
3. Make the base paste: Grind onion, garlic, and tamarind together into a smooth paste.
4. Cook the base: Heat sesame oil in a heavy kadai. Add mustard seeds and curry leaves. Once they splutter, add the onion-garlic-tamarind paste. Cook on medium heat for 10–12 minutes until the raw smell disappears and oil separates.
5. Add spices: Add turmeric and the ground chilli-fennel powder. Mix well and cook for 2 minutes.
6. Add the Nethili: Add the rinsed anchovies and mix gently. Cook on low heat for 12–15 minutes, stirring occasionally, until the fish is fully cooked and the thokku thickens.
7. Finish: Taste and adjust salt. The thokku should be thick, glossy, and deeply red. Add a splash more sesame oil on top before removing from heat.

Serving Suggestions

• With curd rice — the classic Tamil comfort combination
• As a side with idli or dosa for breakfast
• Mixed into plain steamed rice with a drizzle of ghee
• As a spread on bread or roti for a fusion twist

Storage

Store Nethili Thokku in a clean, dry glass jar. It keeps for up to 2 weeks at room temperature and up to 2 months in the refrigerator. Always use a dry spoon to scoop — moisture will reduce shelf life.

Tips for the Best Thokku

• Use sesame oil generously — it acts as a natural preservative and enhances flavour
• Don’t rush the cooking — slow cooking on low heat develops the deep flavour
• Adjust chilli quantity based on your heat preference
• A little extra tamarind adds a pleasant tang that balances the heat
