Trim the broccoli and boil or steam for 5-6 mins until tender but firm to the bite. Drain and cool under cold running water. Heat the oil in a wok or large frying pan, then add the asafoetida, cumin seeds, sesame seeds, chilli, mustard seeds and the curry leaves. Cook for 1 min until fragrant, then add the onion and cook another 2 mins.
Throw in the paneer, ginger and garlic, and season. Cook on a medium heat for 4-5 mins until the paneer turns golden. Add the broccoli and mix through the paneer and spices, then add lemon juice, mace and twist of pepper.
