Potato biryani (aloo biryani)

Biryani is not just a rice dish, but the art of layering (Dum). In this vegetarian version, the potato plays the main role, capable of absorbing every drop of the spicy gravy while the rice on top steams and remains fluffy and fragrant. The essence of the technique is to seal the semi-cooked rice and the juicy base in a pot, so the flavours mature hermetically together.

  • Sieve
  • Mixing bowl

Allergen Information

⚠️ Milk (butter)

Instructions

1

Put the rice in a bowl and gently wash in cold water 3-4 times until the water runs clear. Then soak in cold water for 20 minutes.

Tip: Washing removes surface starch so grains don't stick. Soaking allows grains to elongate and break less during cooking. (Hydration).
2

Peel the potatoes and cut into 3-4 cm cubes. Boil in salted water for approx. 8-10 minutes until the outside is soft but the centre is still hard (parboiled). Drain.

Tip: Parboiling is needed because potatoes would soften with difficulty in the acidic medium during layering. (Slowing of pectin breakdown in acid).
3

Heat the oil and butter in a large saucepan. Add the finely chopped onion and fry over a medium heat until golden brown.

Tip: Darker golden brown onion gives the Biryani its characteristic caramelised base flavour. (Maillard reaction).
4

Stir in the crushed garlic and garam masala. Fry for half a minute until intensely fragrant, then toss in the parboiled potatoes.

Tip: Spices release their aromas when dissolved in fat. (Extraction of aromatic compounds).
5

Pour approx. 100 ml water over the potatoes, add salt and the vinegar. Cook for 2-3 minutes to form a thick gravy.

Tip: This gravy will turn into steam and permeate the rice.
6

Meanwhile, cook the soaked rice in boiling salted water for 4-5 minutes until 'al dente'. Drain.

Tip: The rice should only be 70% cooked, the rest is achieved in the steam.
7

Spread the drained rice over the potato base. Do not mix! Sprinkle the top with fresh coriander. Cover tightly and steam over the lowest possible heat for 15-20 minutes.

Tip: This is the 'Dum' technique: trapped steam cooks the dish and forces flavours into the rice. (Steaming).
8

Before serving, gently toss to mix the yellow spiced rice and white rice.

Tip: Use a fork so as not to break the grains.

Recipe FAQ

Why did my rice break?
You probably overcooked it during pre-cooking, or stirred it too vigorously. Basmati rice must be handled gently, and only cooked to 70% doneness during pre-cooking.
Can I replace apple cider vinegar?
Yes, with fresh lemon juice. The goal is acidity to counteract the starch.
