💡 Tip 1 — Overlapping for Even Burns: Overlap each briquette by about one-third over the next for the most consistent snake burn. Gaps in the snake cause temperature dips and can stall the burn progression entirely.
💡 Tip 2 — Starter Coal Placement Matters: Place your 10–15 lit coals at one end of the snake only. Using too many starter coals raises the initial temperature too high, defeating the purpose of the low-and-slow snake method.

Do not allow that the name fool you, the charcoal snake has any relation to real snakes hanging in your grill. Really it is made up of clever arrangement of blocks from coal, that turns average kettle in the cookout in something, what burns softly and slowly, as well as careful smoker would want. The idea itself is nice and simple.

One arranges long line from unlit blocks along the edge of your #Weber, later one lights little group in one end. While those burned coals burn themselves down, they step by step light the nearby unlit blocks, forming continuous, self-keeping fire chain. Here everything about it in short summary.

How to Make a Charcoal Snake in a Weber Kettle

This method comes from the method of Minion, called after a folk called Jim Minion. The basic thought is, that burned blocks from coal can slowly and passive light unlit ones, while they burn their way along the line. The #Weber kettle became the favorite for this effect, because one does not need special tools or constantly watch during cook.

What makes it so attractive is simply how easy the whole process is.

For setting, usually one lays two rows on the bottom, two more up on them and then one single row on the top. Some favor two wide rows with only one layer up instead. The main point is ensure, that in your snake is not any gap, one wants it as continuous as possible.

If one wants extra taste of smoke simply toss some little wood chunks above it before close the cover.

For start your charcoal snake burn, you need a bit of attention. Light around twelve blocks (or maybe 18 until 24 for bigger grill) in tube for smoking. When they shine red hot, use tongs to lay them in one end of the snake.

One aims for around 10 until 12 burned blocks as starting spot. Do not try add more, easily one overheats the cause. Open the upper vent all the way first, later, when the heat arrives in around 75 degrees under the wanted, turn it to quarter or half.

Close the bottom vent almost entirely.

This effect works well with ribs, brisket and pork shoulder. Usually the cook lasts between 6.5 and 7 hours, keeping the heat in 235 until 250 degrees. Half-turn snake in 22-inch #Weber can keep around 260 degrees during almost 6 hours, although it requires around 45 minutes four reach the heat first.

Blocks from coal are the most used, because their same form gives more stable and expected burn. Natural coal works also, but the results not always are this safe. Get a dual thermometer if it is possible, the built-in dome gauge on many grills is not quite precise enough to trust.

Mind also the weather. Cold days make that your charcoal snake burn itself more quickly. One thing that surprised me is, that fresh coal without pre-lighting can leave carbon taste on the meat.

Use a watercheck in those low temperatures, so that you stay more easily in 250 or less.
