Donot cut the chicken and appply Tandoori masala to it, in the usual way we do for tandoori chicken. You can have small cuts in between the chicken. Now open small can of beer and close the top with potato. Its like not allowing all the beer to vaporise. Now place this in the chicken inside and slowly cook the chicken in oven at low 250 F or in low flam oven for 2 hrs.
Corona beer gives little lemon flavor. If you like any other beer even that is Ok.
