I have a ProQ Excel, similar in style/size to the WSM. The charcoal basket is quite large and obviously for long cooks of 7 hours or so I fill it right up. But should it always be filled? What if I'm only doing 3 hrs for a whole chicken for example? If I only fill it part way will it reach the desired temperature?
Also another question. I used a 5kg bag of briquettes (admittedly from Asda, so questionable quality) using the minion method. I put about 2.5 litres of boiled water from the kettle in the water pan, and for the whole 4-5 hours had the vents open fully. The temperature would NOT go above 200F! After about 4 hours the heat dropped 50F as the charcoal had burnt out. Luckily I was cooking lamb and it had hit 60C giving a nice pinkish meat.
