Before You Start
A samosa is judged by its shell at least as much as by what is inside. The pastry should crack cleanly when you bite it, not chew or bend. No single trick gets you there. It comes from a firm, under-hydrated dough, a long and slow fry, and a seal strong enough that no filling escapes into the oil and burns. The filling is the easier part: potato, peas, and whole and ground spices, seasoned boldly because the pastry around it adds almost no flavour. This recipe uses the cone fold you see at North Indian samosa stalls. You pack the cone generously, close it, and fry in batches over patient, moderate heat, not quick and hot.
Where This Dish Comes From
The pastry tradition behind the samosa did not begin in India. Filled pastry triangles and pockets, fried or baked, were being made in Central Asia and the Middle East long ago, and the samosa's ancestor is usually traced back to those lands by food historians. It travelled to the subcontinent along trade routes and into royal kitchens in the medieval centuries, a good while before the Mughals arrived. Early Persian and Arabic texts describe a meat-filled pastry called sanbusak or something similar. Once in India it was adapted widely, with fillings changing to suit regional and religious diets. The familiar spiced potato and pea filling gained its hold in North India only after Portuguese traders brought the potato in the sixteenth and seventeenth centuries, so the vegetarian potato samosa most people picture today is a fairly recent version of a much older pastry form. Variants still differ across India, from the flatter, differently folded Bengali shingara to South Indian versions with other spicing, which is why it would be inaccurate to tie the samosa to a single Indian region. India adapted it and then diversified it from within.
Step by Step
-
Prep
Make a stiff, lightly hydrated dough
Work the oil or ghee into the flour, ajwain and salt with your fingers until a handful holds its shape when squeezed. This step of rubbing in fat is what gives fried pastry its flaky layers. Pour in the cold water bit by bit and knead into a stiff, smooth dough, firmer than roti dough, that doesn't stretch when pulled. Cover it with a damp cloth and let it rest for 30 minutes.
-
Cook
Cook the filling
Warm the oil and let the cumin and fennel seeds sizzle until fragrant. Stir in the ginger and green chillies for a moment, then the peas, and cook for 2 to 3 minutes. Add the coriander powder, garam masala, amchur, chilli powder and salt, followed by the mashed potato, breaking it up only partly so some texture stays. Keep cooking for a further 2 to 3 minutes until the spices cling to everything, and finish with the fresh coriander. Let it cool completely before filling, because warm filling softens and weakens the pastry while you work.
-
Prep
Roll out and halve the pastry
Break the rested dough into 6 even balls. Roll every ball into an oval roughly 15cm long and 2 to 3mm thick, and cut each oval across the middle into two semicircles. You will end up with 12 pieces.
-
Prep
Form each cone and fill it
Pick up a semicircle and brush its straight edge lightly with flour-water paste. Curl it into a cone and press the seam firmly shut. A weak seam is the commonest reason samosas burst open in the oil. Spoon in the cooled potato mixture generously, packing it down but stopping short of the very top.
-
Prep
Close the top
Pinch pleats into the open top edge and press them shut with a dab more flour-water paste, then flatten the base a little so the samosa can stand upright. If it is sealed properly, it will keep its shape when you squeeze it gently.
-
Cook
Fry slowly over moderate heat
Bring the oil to roughly 300 to 325°F (150 to 160°C), clearly cooler than for most deep-frying, and on purpose. Slide in a few samosas at a time and fry gently, turning now and then, for 15 to 18 minutes, until they are deep golden and firm all over. The long, gentle fry cooks raw pastry right through to a flaky crispness without the outside browning before the inside sets. Hotter, faster frying produces a pale, blistered or doughy shell.
-
Cook
Drain and rest before serving
Lift the samosas out with a slotted spoon and set them on a wire rack, not paper towels, which hold steam against the underside and soften it. Let them rest a few minutes before serving; they bite cleanly once they have firmed up a little out of the oil.
Swaps That Work
Ghee in the dough instead of oil gives a richer, more old-fashioned flavour, and it can take the place of some or all of the oil. For variety, add cauliflower, carrot or paneer to the filling or use them in place of some of the potato, although classic samosas keep mostly to potato and peas. Fennel seeds can simply be left out if you have none; they add a gentle anise note that is traditional but not essential. Frozen peas work as well as fresh and go into the pan without thawing.
Turning the Heat Up or Down
Chilli heat in the filling comes from the fresh green chillies and the red chilli powder, and you can adjust both before you cook. For a milder samosa, leave out the green chillies and cut back on or skip the chilli powder, relying on garam masala and amchur for flavour. For a hotter filling, use more of both and add some crushed dried red chilli. Taste the filling while it is still warm, because flavours dull a little once cold, and adjust salt and chilli together instead of separately.
Where Cooks Often Slip
Dough that is too soft or too wet gives pastry that bubbles, blisters or turns tough instead of flaky, so keep it firm and add only as much water as it takes to bring it together. If the filling is still warm when you shape the samosas, it steams inside the pastry and softens it from within before frying even begins; cool it fully first. Oil that is too hot colours the outside before the middle is cooked, so you get a pale or raw-tasting centre beneath a dark crust. Keep the heat moderate and be patient about timing. Finally, a poor seal at the seam or the top pleat is why a samosa splits and leaks filling into the oil, which also darkens the oil faster for the rest of the batch. Press seams firmly and be generous with the flour paste.
Keeping and Warming Up Leftovers
To keep it: Fried samosas will keep for up to 3 days in a sealed container in the refrigerator. You can also shape samosas and freeze them unfried: lay them on a tray until solid, then move them to a freezer bag, where they last up to 2 months. Fry them straight from the freezer at a slightly lower temperature for a few extra minutes instead of thawing first, since thawing can make the pastry soggy before it reaches the oil. If you make the filling ahead, the cooked mixture keeps in the fridge for up to 3 days.
To warm it up: Put fried samosas back into a 375°F (190°C) oven or an air fryer for 8 to 10 minutes, until the pastry crisps up again and the filling is hot in the middle. A microwave can't match that, as it leaves the pastry soft and slightly chewy. Cooked samosas coming from the freezer need a few extra minutes, and you should check that the centre is hot before serving.
Kitchen Safety Note
Cool boiled potatoes and the cooked filling promptly after cooking and don't leave them standing at room temperature; refrigerate them within about two hours if you aren't using them right away. If possible, use a thermometer to keep the frying oil between 150 and 160°C. Oil that overheats and starts smoking has begun to break down and should not be reused. Keep frying oil for later only if it stayed in a sensible temperature range and still smells clean. Throw it out when it has turned dark, smells sharp and acrid, or has served more than a handful of frying sessions, and never top up badly degraded oil with fresh oil to stretch its life.
