1. You could add more green chillies or black pepper according to your spice level.
2. Drain the cauliflower florets well before tossing them in the tempered hot oil to avoid any spluttering of oil or burns.
3. The Cauliflower absorbs enough salt from soaking in salted water so there’s no need to add more salt, but you could do a taste testing in the end and check to see if it needs more. And if you want to add more salt do sprinkle a little water after adding it then sauté till the water evaporates.
