Preheat the oven at 200℃
Bring the chicken to room temperature
In a mortar and pestle put up all the listed ingredients for marinade except oil and bash them up well.
Now add oil to this and form a paste
Rub this paste all over the chicken, inside out.
Make sure you cover all the nook and crannies
Crack open the can and pour it in another can till it is just half full
Then lower the cavity of the chicken on top of the beer can and press it tight so that it just looks as if the chicken is sitting on the can
Carefully sit the chicken on the very bottom of the oven
Cook for 1 hour 10 minutes to 30 minutes or until the flesh pulls away from bone
All ovens have different temperature so you might have to just keep a little longer
Once done carefully remove the can and cover the chicken
