Common Charcoal Grilling Mistakes

1. Using lighter fluid

Lighter fluid works, and it also leaves a chemical taste that no amount of smoke covers up, particularly on fast cooks where the food goes on soon after the coals do. Match-light briquettes are the same problem in a more expensive package: they are just briquettes pre-soaked in the stuff. The fix costs about the price of two bags of charcoal and lasts a decade — a chimney starter, some newspaper, one match. It is faster than fluid too, because the coals come out evenly lit rather than lit on the outside and cold in the middle.

2. Pouring the chimney too early

This is the most common single error, and it is easy to make because a chimney looks dramatic long before it is ready. Flames coming out of the top mean the paper and the bottom layer are burning; that is not the signal. The signal is the coals at the very top turning gray with ash, which tells you the whole load has caught. Pour before that and you get a fire that keeps climbing while you are trying to cook, then collapses without warning twenty minutes later. Give it the full 10 to 15 minutes and use the time to prep the food.

3. Spreading the coals evenly across the grate

An even bed of coals seems logical — even heat, even cooking — and it is the arrangement that causes the most burnt dinners. It leaves you nowhere to put food that is browning too fast, so when something flares your only options are to take it off the grill or watch it char. Bank every coal onto one half of the grate instead. The empty half is not wasted space; it is the entire reason charcoal is forgiving. Sear over the coals, move across when you need to, close the lid to finish. The setup is covered properly in charcoal grilling for beginners.

4. Lighting too much charcoal

More fuel feels like more control and is the opposite. A grill loaded with charcoal radiates so much heat that closing the intake vent barely touches it and the “cool” side is not cool, so the escape hatch you built does not work. One full chimney is the everyday amount for a 22-inch kettle; half that for a small grill or a small amount of food. Amounts for every kind of cook are in our charcoal cheat sheet.

5. Not preheating the grate

Pouring the coals and immediately putting food on gives you a hot fire and a cold grate, which is exactly the condition food sticks to. Fit the cooking grate, close the lid, and give it five to ten minutes before anything goes on — then brush the hot grate one last time. Most sticking that gets blamed on oil, or on the grate being cheap, is a preheating problem.

6. Cooking with the lid in the wrong position

The lid is not decoration and it is not a permanent setting. Thin, fast food over direct heat — burgers, dogs, thin steaks — is fine with the lid off. Anything thick that has to cook through needs the lid closed so the grill works like an oven, or the outside will be finished long before the middle is. The rough rule: if it will be done in under about eight minutes, lid off is fine; longer than that, lid down and move it to the indirect side.

7. Opening the lid every two minutes

Every time the lid comes off, the heat you built up leaves and a rush of oxygen hits the coals, which spikes the fire and then leaves it lower than before. On a short cook this costs you consistency; on a long one it is why a rib cook takes an hour longer than the recipe said. Check when you have a reason to check — a flip, a temperature reading, adding fuel — and otherwise leave it alone.

8. Choking the vents to control the heat

Closing the vents down does lower the temperature, and closing them a long way does something else: it starves the fire of oxygen so it smoulders instead of burning, and a smouldering fire makes bitter, sooty smoke that settles on the food. If the fire is too hot, close the bottomvent partway, leave the top vent open, and wait five to ten minutes for the fire to respond before touching it again. Closing both vents fully is how you put the fire out at the end of the cook — that is its only job.

9. Pressing the burgers (and other fat-driven flare-ups)

Pressing a patty with the spatula squeezes rendered fat straight onto the coals, which produces the flare-up, which burns the outside of the burger, while the juice you just squeezed out is the thing that would have kept it moist. There is no upside. When a flare does happen — and it will, because fat drips — move the food to the empty side of the grill and close the lid. It dies in seconds without air and without fuel dripping into it. Do not throw water on it: that throws ash over everything.

10. Cooking to time instead of temperature

Every timing in every recipe is a guess about a fire that is not yours, on food that is not the same thickness as yours. The USDA is explicit that color is not a reliable indicator of doneness — a burger can brown through and still be under temperature, or look pink and be perfectly safe. An instant-read thermometer in the thickest part, checked against the USDA safe minimums, converts the whole thing from guessing to knowing, and it is the cheapest upgrade in barbecue. The full field is in best meat thermometers.

Two more worth avoiding

• Wire-bristle brushes.A bristle that works loose can end up in food and then in someone’s throat, and the injury data shows the problem getting worse rather than better. Bristle-free scrapers and steam-style brushes do the same job; the ones we’d buy are in best grilling tools.
• Leaving ash in the bowl. Ash holds moisture against the steel and rusts a grill from the inside, and a bed of old ash also blocks the bottom vent so your next fire never gets the air it needs. Sweep it out once everything is cold.

The pattern behind all of them

Nine of these ten are impatience in different costumes: pouring early, skipping the preheat, opening the lid, chasing the temperature with big vent moves, cutting into food instead of probing it. Charcoal rewards doing less, more slowly, than instinct suggests. The fire does what you tell it — it just answers about five minutes after you ask.
