• 1500 mlWater (For boiling potatoes)
• 8 gFine salt (5 g for boiling water, 3 g for seasoning)
• 15 mlNeutral oil (Sunflower or canola)
• 120 gYellow onion, finely diced
• 6 gGarlic, finely grated (About 2 cloves)
• 2 tspGround cumin
• 1.5 tspGround coriander
• 0.5 tspTurmeric
• 0.5 tspBlack pepper
• 0.25 tspRed chili flakes (Optional but traditional for gentle heat)
• 20 gFresh cilantro, finely chopped

• 15 mlLemon juice
• 12Spring roll wrappers (About 20 x 20 cm squares)
• 30 gAll-purpose flour (For sealing paste)

Instructions

1. 1

   Boil the potatoes: add the cubed potatoes to 1500 ml water and stir in 5 g of the salt. Bring to a steady boil, then cook until the cubes are tender but not waterlogged, about 10–12 minutes. Drain very well and let the steam escape for 5 minutes so the filling stays dry and crisp when fried.

2. 2

   Build the spice base: warm 15 ml neutral oil in a skillet over medium heat and cook the onion for 6–8 minutes until soft and lightly golden. Add the garlic and cook for 30 seconds, then stir in cumin, coriander, turmeric, black pepper, and chili flakes for 20 seconds to bloom the spices. This quick toasting deepens aroma and prevents the filling from tasting flat.

3. 3

   Finish the filling: add the drained potatoes to the skillet and toss to coat in the spiced onion mixture. Mash about one-third of the potatoes with a spoon while leaving the rest in small chunks for texture, then mix in the remaining 3 g salt, cilantro, scallions, and lemon juice. Cool the filling to room temperature for 15 minutes so steam does not soften the wrappers during folding.

4. 4

   Prepare a sealing paste: whisk 30 g flour with 45 ml water until smooth and thick like glue. Keep it covered so it does not crust over while you fold. A proper paste is essential for tight seams that will not open in hot oil.

5. 5

   Fold the sambosa: place one wrapper on a board and cut it in half to make two rectangles, then fold each rectangle lengthwise into a long strip. Spoon 30–35 g filling near one end and fold into a triangle, continuing to flip the triangle along the strip until you reach the end. Brush the final flap with sealing paste and press firmly for 10 seconds to lock the edge.

6. 6

   Fry until crisp: heat 800 ml neutral oil in a pot to 175°C and fry 4–5 sambosa at a time for 3–4 minutes, turning halfway, until deep golden and blistered. Maintain the temperature between 170–180°C so the pastry crisps without absorbing excess oil. Drain on a rack for 2 minutes before serving to preserve crunch.
