Heat a cast-iron griddle (tava) and add oil. Let the oil heat up.
Once the oil is hot, add fenugreek seeds and roast them well. Then, add cumin seeds and roast them until fragrant.
Add a little turmeric powder, then add the long-cut potatoes that have been washed and drained.
On medium heat, saute the potatoes for 2-3 minutes, mixing them well. Continue to stir occasionally for about 5-7 minutes until they are well roasted. There's no need to cover them with a lid.
Create a space in the centre of the pan where some oil remains. Add the crushed garlic cloves and saute them until they turn a light golden colour.
If desired, add the dry red chillies.
Mix all the ingredients together well on medium heat.
Add the finely crushed black peppercorns and salt to taste.
Saute everything together for another 2-3 minutes on medium heat.
The dish is ready to be served.
Tips: This recipe is very flavourful and doesn't require chilli powder or even the dried red chillies if you prefer; only the black pepper and salt are sufficient.
