Peel and cube the potatoes. Slice the bamboo shoots if they are not pre-sliced.
Heat oil in a pan over medium heat. Add cumin seeds and let them sizzle.
Add finely chopped onions and cook until they turn golden brown.
Stir in the ginger-garlic paste and cook for another 2 minutes until the raw smell disappears.
Add diced tomatoes, turmeric powder, coriander powder, red chili powder, and salt. Cook until the tomatoes become soft and the oil starts to separate from the masala.
Add cubed potatoes and sliced bamboo shoots to the pan. Mix well to coat the potatoes and bamboo shoots with the spice mixture.
Pour in enough water to cover the vegetables. Bring to a boil, then reduce heat and let it simmer for about 20-25 minutes or until the potatoes are cooked through and tender.
Stir in the garam masala and cook for an additional 2-3 minutes.
Garnish with freshly chopped coriander leaves.
Enjoy your meal!
