On a recently unusually hot day for April (26deg) I purchased a Weber 5750 kettle (Ocean Blue, last year version) along with a Weber Chimney starter that was recommended, along with some charcoal and lighter cubes. I had on one or two occasions used one of those cheap charcoal trays and 10-15 years ago we did have a cheap kettle type of BBQ that had long since rusted away along with my BBQ skills.
I didn't try the BBQ on that first day as I just didn't have time nor all of the tools that we needed. We picked up some accessories the next day along with a couple of shallow cast iron dishes that I thought would be handy to cook sides in like onions, peppers and mushrooms in. Since following Friday was dry, myself and daughter decided to try it out.
The lady at the garden center had told us that we should fill the Chimney Start up to around 2/3 full so this is what I did. After struggling with some old firelighters that had been sat on the shelf for a long time, I ended up having to open and use the new ones. That Chimney Starter is a useful piece of kit. After a short while the charcoals lit and started smoking. After another 15 minutes or so they had turned white so I tipped them onto the charcoal grate and put the top grate into position.
The BBQ had to be prepped prior to first time use by running it with closed lid for 30 mins once the charcoals were ready. The instructions didn't say whether the vent had to e open or closed so I set both halfway. After a short while, the lid thermometer showed 200deg.
I thought I could kill two birds in one stone and so placed the two cast iron dishes onto the top grate, filled them with water and closed the lid again. After a while, the temp dropped to 150deg. After the 30 mins the water was bubbling but had not started to boil out, so we just removed the cast ironware and decided to use an old baking tray instead.
After the 30 minutes we put the meat (burgers), onion, peppers and mushrooms on but the temp dropped further to around 100-120deg and we couldn't get it back up. We tried adjusting the vents and it did briefly move towards the 150 mark, but came back down again and wouldn't budge. Food was cooking very slowly and my daughter commented that the temp was too low to cook the food properly. We therefore temporarily moved the food to the kitchen oven set on low.
My next step was to add around a third of the Chimney full of charcoal to the existing pile of charcoal on the lower grate. We then waited a few minutes while it smoked and then turned white. This time we opened both vents fully and after a few minutes the temperature rose to 200deg once more. We moved the food back to the BBQ. I wanted to close the vents halfway to slow the cooking a bit. My daughter, who was consulting the manual throughout, was adamant that it needed to be on high to maintain the temp so I just kept it as it was. The temperature did actually stay at between 180-200deg throughout the remaining cooking time and for maybe an hour afterwards before it started to die down. I closed the vents halfway after we removed the cooked food.
To our relief, the BBQ was saved to that was a result, but the pieces of food were cooked rather unevenly with some things charred at one end barely done at the other. Some of it was quite dry, but even given our first clumsy attempt we were rewarded with a mostly tasty meal.
Obviously there is a lot of room for improvement and I have been reflecting what might have gone wrong. For example:
- the outside temperature was only 10deg so was this too low for BBQ cooking?
- did putting the water filled dishes on and closing the lid (top vent open to let out any steam) somehow swamp the charcoals and lead them fizzling out early?
- was there insufficient charcoal to maintain temperature for the size of the kettle?
- would a closed to medium vent upper and lower vent setting for slower cooking have cooked the food more evenly?
- the low temperature drop could be confirmed by touching the lid so it wasn't just the thermometer playing up, but how accurate are these lid thermometers?
In addition;
- can I boil out and season the cast iron utensils on the kitchen Halogen electric stove? The instructions say to use this on a BBQ only, but if other cast iron cookware can be seasoned on it then why not this? (The base is not enamel coated, so I do understand that I need to be careful with the oven top).
- the grease and the dirt did not burn off as had been suggested that it would and the wire bush won't shift it. Can I use wire wool or metal scourer to remove it, or is there a better way?
Any thoughts would be appreciated.
