TIP: Basting is not needed as the required oil is already soaked in the chicken during marination. This helps the chicken to be cooked well from within. It will also make the chicken soft and juicy. If you feel you can still do it. No harm.
NOTE: Other refined oil can also be used instead of mustard oil during marination, but trust me the mustard would sensitize an altogether different set of taste buds than the usual ones. You should, at least, try this once….
