Preheat the oven (top and bottom heat) to 230°.
Wash the chicken and pat dry, no offal is needed. Mix the spices for the rub in a bowl and rub the chicken completely. If you brush the chicken with some olive oil beforehand (approx. 1 tbsp.), the dry marinade will stick better.
Then put the rooster aside and let the Rub take effect.
Pour away or drink half of the beer and place the can in the middle of a wide (round) bowl. Wash the lemon well, cut it in half and squeeze one half. Add the juice to the beer in the can - watch out, it foams! Also put the garlic and the thyme, which has been washed naturally beforehand, into the can.
I also added 2 small slices of the remaining lemon.
Now it is time to put the chicken on the beer can and put it with the shell into the oven. Now roast the chicken at 230° for 10 minutes, then turn down to 165° and cook in the oven for another 50 - 60 minutes.
Then take the dish out of the oven (again, skill is required) and remove the tin from the chicken - we chose the rough, albeit somewhat unclean, multi-towel and pot cloth solution.
Place the chicken on a plate/plate/wood board, divide it with a large knife/poultry shears and put it on the table.
