Called a few different spice shops in the area and none of them stock Rajah products, most of them suggested Kitchen King Masala as an alternative.
Ingredients are as follows:
Coriander, Chilli, Turmeric, Cumin, Dal, Fenugreek, Pepper, Salt, Cardamom, Ginger, Cinnamon, Cloves, Nutmeg, Mustard, Garlic, Mace, Asafoetida.
A little worried about this, based on the ingredients do you think it would be ok to add this as a substitute for Rajah Madras powder?
