Heat oil in a pan at medium heat. Once it’s hot, add cumin seeds and fennel seeds. Wait for few seconds or until it’s become a slightly brown in color. Add green chili and saute it for few sec. Add mutter (peas), corn kernel and little salt (please note chaat masala and black salt also adds to salt so don’t add too much of salt at this stage). Saute it till all moisture from mutter and corn dries away. Add chaat masala, chili powder, crushed coriander, amchoor powder, coriander & mint chutney and black salt into it. Coriander mint chutney gives a nice minty taste to it.
