Sapporo Japanese Beer is now on sale at Lidl Deltebre at 1.99 a can. These are big cans.Albeit the beer is brewed in Canada it still has that distinctive smooth taste served cold from the fridge. I have had the stuff from Japan and the taste is the same. The can itself is very sturdy indeed and what I do is save a couple of empty cans.
Close your Barbecue lid and let the temperature get high and then half fill the beer can with water or you can use beer and place a chicken on top with the can going into the cavity then close the lid. The chicken is then cooked and is wonderfully moist with a nice crisp outside. I have done it this way just found this to show you.
