Chop cauliflower florets to 1½ inch in size. Add them to slightly hot water and set aside for 3 to 4 mins. This step helps to remove any impurities and makes the cauliflower tender.

Drain the water and rinse the cauliflower well. Drain them completely to prevent excess moisture in the dish.

Cube potatoes to ¾ by ¾ inch. You can also slice them to ¾ inch. Keep them immersed in a bowl of water until used. This helps the potatoes to cook faster as they soak up some moisture.

Mince ginger and garlic. Keep this aside for later use.

Heat oil in a pan and add cumin seeds. When they sizzle, add ginger, garlic, and sauté for 30 seconds. This step releases the aroma of the spices and adds flavor to the dish.

Then add the onions and stir-fry until transparent. This step helps to bring out the sweetness in the onions.

Add the potatoes and green chili. Stir-fry for 2 to 3 mins. Cover and cook on a low to medium heat until they are half done. If required, you can splash some water so they cook faster.

Keep stirring in between and cook covered. This ensures even cooking and prevents the potatoes from burning.

When they are slightly tender but still undercooked, add the cauliflower and stir-fry for about 3 mins. This step helps to distribute the heat evenly and prevents the cauliflower from becoming mushy.

Add red chili powder, turmeric, roasted cumin powder, garam masala, and coriander powder. Mix well to combine the spices evenly.

Sprinkle 2 to 3 tablespoons of water all over the aloo gobi or across the sides of the pan and mix well. This step helps to keep the aloo gobi moist without drying out.

Cook covered, stirring every few minutes, until both aloo and gobi are almost fork-tender. Add salt and continue to cook covered on a low flame until the potatoes are soft and fully cooked.

The veggies will release moisture at this stage and cook quickly. So keep an eye not to overcook gobi at this stage. It must remain slightly crunchy yet cooked.

Next, add the tomatoes and kasuri methi. Fry on a medium to high flame until the raw smell of tomatoes is gone. This step adds a burst of flavor and texture to the dish.

If needed, add a little oil at this stage. It takes about 2 to 4 mins for the raw smell of tomatoes to go away.

Sprinkle amchur if using. Finally, garnish aloo gobi with coriander leaves. Sprinkle some lemon juice if you want. Serve with rice, roti, or any bread.
