Smoked ribs in a kamado: 3-2-1, 2-2-1 or no wrap

Each number is a phase, in hours. In the 3-2-1, the rack spends three hours bare in the smoke, two wrapped with a little liquid and one unwrapped, painted with sauce. That comes to about six hours. Steven Raichlen, who first came across it while researching his book Best Ribs Ever, gives a working range of 225-250 °F (107-121 °C) and recommends it mainly for spare ribs (costillar de panceta) and their trimmed version, the St. Louis.

The 2-2-1 takes an hour off the smoke: about five hours for baby back ribs (loin ribs, costillar de lomo), which are shorter and leaner. It is the only line our table gives for ribs, with 110-120 °C in the chamber and 90-93 °C internal; here it is refined by cut and by cooker. Raichlen even proposes a 2-1-1 when the 2-2-1 leaves baby backs too soft. And our barbecued ribs recipe follows a 3-1-1 at 130 °C with a final direct sear.

No wrap means smoke from start to finish, with sauce at the end if you want it. It gives more bark and more bite; the same recipe suggests it this way: about four hours at 110 °C without paper and half an hour with sauce.

The Big Green Egg and Kamado Joe rib recipes consulted run hotter and shorter. Big Green Egg's baby back recipe cooks at 325 °F (163 °C) with the convEGGtor: an hour and a half uncovered and an hour covered in a tray with apple juice. Kamado Joe's pork rib recipes run at 300 °F (149 °C): about two hours for a baby back, one of them wrapped, and about three for a St. Louis, also in foil. None skips the wrap, but the wrapped stretch is around an hour: that supports moving from 3-2-1 to 3-1-1, or from 2-2-1 to 2-1-1, in a kamado. With only three hours, the hot route works, with a different bark.

Ask for the rack "whole, uncut" ("entero, sin cortar"): at the counter, costillar means strips cut across the bones by default. The full order is in the guide to cuts and equivalents; here is just what you need to choose a method.

- Baby back: loin or carré rack (costillar de carré or de lomo), short and curved, 1-1.3 kg. - Spare ribs: belly rack (costillar de panceta), longer, flat and fatty, 1.5-2 kg. This is the cut the 3-2-1 was made for. - St. Louis: the squared-off belly rack, without the breastbone or the cartilage at the tip. It weighs less and cooks more evenly.

According to Iowa State University Extension, a rack of spare ribs has between 11 and 13 bones, and close to half its weight is bone and cartilage; in a baby back the proportion is similar, and the number of bones depends on the trim. Its weights, for American racks, are slightly lower than the cuts guide's: about 0.9 kg for a baby back and 1.1-1.6 kg for spare ribs. Ask for the weight when you order.

Ibérico or Duroc pork has more marbling than Spanish white pork, which is raised lean, and that gives it more leeway unwrapped; white pork dries out sooner and welcomes the paper. This is reasoning, not a measurement: start with a short wrap and adjust.

A whole rack of spare ribs rarely lies flat on the grate of a large kamado, about 46 cm across. Cut it in two, roll it or stand it up in a rib rack: its spec sheet says up to five racks, but on a 46 cm kamado three or four fit depending on their size, and a small kamado may lack height under the dome.

The membrane is the silvery skin on the bone side. If you leave it on, neither smoke nor rub gets through it and it cooks up leathery. Lift a corner with the tip of a knife, grip it with kitchen paper and pull diagonally.

Salt or rub goes on in advance. Iowa State Extension notes that many recipes season at least four hours ahead; one of Kamado Joe's recipes is happy with half an hour. The night before, covered in the fridge, also works. More rub does not give more flavour, it gives more salt, and there is no sourced dose in grams per kilo: start light.

A binder is optional. A very thin layer of mustard only helps the rub stick and you cannot taste it at the end. A little oil does the same.

There is no need to bring it to room temperature: half an hour out of the fridge while you light the fire is enough, and USDA FSIS advises against going beyond two hours.

Ribs always go indirect: over a direct fire they char before they soften, as the guide to direct and indirect cooking explains. On a Big Green Egg Large, the convEGGtor or a 44.5 cm cordierite deflector does the job; on a Kamado Joe Classic, the half-moons. Leave an air gap between deflector and grate and, in that gap, two drip trays with a little water in the bottom or on spacers, as their spec sheet advises: sitting dry on hot ceramic, the fat smokes sooner and turns bitter.

The target is 110-120 °C in the chamber, measured with a probe at grate level. The dome thermometer reads the air above and, with the deflector in, can differ from the grate by 10-25 °C, according to the guide to thermometers and probes. Clip an ambient probe to the grate, close to the rack without touching it. A ThermoPro TP25 with four probes leaves one for the chamber and others for one or two racks.

The charcoal goes in with the Minion method: a basket full of unlit charcoal and a handful of glowing coals on one side. That load is more than enough for ribs.

The wood, following the guide to smoking woods, is two or three chunks, about 100-150 grams, buried at different depths. For pork, apple chunks, cherry and olive all work; with hickory, use a single chunk. Put the meat on when the thick white smoke from lighting turns almost clear, ten to twenty minutes later.

After that, open the lid as little as possible and always with burping: lift it about five centimetres, wait about five seconds and then open fully.

Wrapping speeds up the cook, because it cuts the evaporation that cools the surface, and it softens the meat, because the rack cooks in its own steam. Raichlen sums it up: wrapping in foil is boiling them in their own juices. That gives you the tenderness, and also a soft bark and a slightly washed-out flavour.

- Foil: airtight. It is the fastest and most tender route, and the one that punishes the bark most. Use a double sheet, because the bones puncture a single one. - Butcher paper: lets some of the steam through. Kamado Joe explains it in its beef rib recipe: foil is not permeable and partly steams the bark. A 45.7 cm-wide roll of butcher paper wraps a rack with room to spare. - Nothing: more bark and more bite, in exchange for more time and some risk of drying out a lean white pork rack.

In a kamado, wrapping matters less than in a smoker. The sealed chamber holds in plenty of moisture, the bark takes longer to form and wrapping early leaves it soft. The sensible move is to halve the wrapped phase or switch to paper. That is a deduction from the data cited here, not a measurement of our own.

The liquid is a small splash: in our St. Louis recipe, 100 ml of apple juice and 50 g of butter for two racks. Jeff Phillips, who publishes the 2-2-1 on a Big Green Egg, prefers to add nothing.

The moment is set by the bark: set, mahogany in colour and not sticking to your finger. In one recipe Kamado Joe gives a reference of at least 74 °C (165 °F) internal. Ribs also hit the stall, but because they are thin it lasts much less than on a brisket or a pulled pork. Wrapping to get through it is the Texas crutch.

With ribs, a probe pushed in tells you little: the meat is thin and the tip easily touches bone. The three tests Raichlen describes work better.

- Bend test: lift the rack with tongs from the middle. If it bows easily and the surface cracks, it is done. Our recipe makes this concrete: it bends about 30° without breaking; if it snaps, it has gone too far. - Toothpick: it slides in between two bones with only slight resistance. - Bone showing: the meat pulls back and leaves the ends of the bones exposed.

Temperature confirms. Our table gives 90-93 °C internal; Raichlen puts the finish between 195 and 205 °F (90-96 °C) and Kamado Joe at about 200 °F (93 °C). Measure it with an instant-read thermometer such as the ThermoPro TP19H, between two bones and without resting the tip on the bone, which throws the reading off.

Why is 63 °C not enough? USDA FSIS sets 145 °F (62.8 °C) with a three-minute rest for whole cuts of pork. From there ribs are safe but, as Iowa State Extension points out, still tough. Tenderness arrives when the collagen between the bones turns to gelatine, at about 88-93 °C internal.

The sauce goes on in the last 15-30 minutes. It contains sugar, and sugar burns and turns bitter if it spends hours in the heat.

The direct sear is optional. In our St. Louis recipe the deflector comes out, the temperature goes up to 260 °C and the ribs get 60-90 seconds a side. That means moving hot ceramic: proper gloves and somewhere ready for the deflector, on stone or metal and away from your feet. And burp before opening: after hours with the vents almost closed, the chamber builds up unburnt gases and the sudden rush of air ignites them at once; that is the flashback.

Resting is short: 10 minutes in our recipe, about 20 wrapped in Kamado Joe's baby back recipe. Longer only cools them.

To carve, put the rack bone side up: that way you can see where each bone runs. Cut between the bones with a long knife, in a single stroke. If they fall apart as you cut, they went too long in the wrapped phase. Leftovers go in the fridge within two hours, or one if it is above 32 °C (90 °F): that is the USDA FSIS rule.

The table sums up method, temperature and approximate time by cut. For servings, 1 kg of ribs on the bone feeds about two people; the full calculation is in the last FAQ.

- Dry: the chamber was hotter than you thought, or a lean rack spent the whole time unwrapped. Measure at the grate and try paper. - Tough: they need more time. Carry on until they pass the bend test and the toothpick. - Falling apart: too long wrapped or too much liquid. Raichlen suggests shortening the wrapped phase by 30 to 60 minutes. - Soft bark: foil or wrapping too early. Open the paper for the last 10-15 minutes. - Bitter: almost always dirty smoke, from putting the meat on in white smoke, too much wood or throttled vents. The guide to bitter smoke and creosote explains it. If the bitterness is only in the glaze, it was burnt sauce.
