Quick answer
Yes, if you own a Big Joe and want smash burgers, cuttlefish or griddled vegetables without giving up half a grate of live coals. It is cast iron with a smooth face and a ribbed face, declared compatible with Big Joe I, II and III. It weighs 6.35 kg, needs drying and oiling after every use, and is no use on a 46 cm Classic.
Cast iron, 60.96 x 30.48 x 1.91 cm and 6.35 kg: exactly half of a 24-inch grate. It sits in the Divide & Conquer rack of a Big Joe I, II or III and leaves the other half free for the grate. Big Joe only: it will not fit a Classic.
The Half Moon Griddle for Big Joe (model BJ-HCIGRIDDLE) is a reversible cast iron half-moon: one smooth griddle face and one ribbed grate face. The listing publishes 60.96 x 30.48 x 1.91 cm and 6.35 kg. Those 60.96 cm are exactly 24 inches, the diameter of the Big Joe, and the 30.48 cm are half of that, so it takes up precisely one semicircle of the [Divide & Conquer](/glosario#divide-and-conquer) rack. Kamado Joe declares it compatible with Big Joe I, II and III. Declared manufacturer: Premier Specialty Brands, LLC; country of origin, China; documentation in English.
The point of a half griddle is not having to choose. You mount this piece on one half of the Divide & Conquer and the standard grate on the other: smooth plate for pressing the patty of a [smash burger](/recetas/hamburguesa-smash-kamado) and grate alongside for toasting the bun over the coals. Flipped over, the ribbed face leaves sear marks and drains fat into the grooves, useful for vegetables and thin cuts. With 6.35 kg of iron in a half-moon (the listing's 1.91 cm is overall height including the ribs; by weight the solid iron averages around 6 mm, our estimate), the thermal mass is considerable: it takes a while to come up to temperature, but then it does not collapse when cold meat lands on it.
The fit is as simple as it is restrictive. This piece is for the 61 cm ring of the Big Joe, and for that alone. On a Classic Joe, a Big Green Egg Large or any 46 cm kamado it will not go in even on the diagonal; for those there is the Classic version of the same griddle, already in our catalogue. On a Big Green Egg XL, which is also around 61 cm, the listing declares nothing, neither for its grate nor for its own multi-level system: measure before taking the fit for granted. In the Big Joe you can drop it to the level nearest the charcoal for a hard sear or raise it to the upper level for a gentler griddle.
The drawbacks lie almost entirely in what the listing leaves unsaid. It specifies neither whether it comes pre-seasoned nor whether the iron is bare or enamelled; when in doubt, treat it as bare iron: plan on a thin coat of oil and a good heating before first use, and on drying and oiling it after every wash, like any cast iron; our [guide to cast iron on a kamado](/guias/hierro-fundido-y-dutch-oven-en-kamado) walks through the ritual. It publishes neither a warranty nor a maximum temperature. The 6.35 kg make themselves felt when you lift it out hot through the mouth of the kamado. What is on record: 4.7 out of 5 from 299 ratings and number 229 in Amazon.es's list of barbecue and smoker griddles. Today it shows as in stock and without a Global Store label; if you see another seller, check where it ships from.
We have not had it in our hands, and our Big Green Egg Large will not take it. What the listing does say, along with the physics of cast iron, is that the measurements match the Big Joe to the millimetre and the material is the right one for griddling over coals. Verdict: if you own a Big Joe and are missing the griddle half of the Divide & Conquer, this is the official piece that fits; if your kamado measures 46 cm, look for the Classic version.
The official half griddle for the Big Joe: solid cast iron, two faces and exact 24-inch measurements. Big Joe only, no seasoning declared, and 6.35 kg you will notice when lifting it out hot.

MixRBBQ Half-Moon Ceramic Heat Deflectors (Kamado Joe Big Joe I/II/III, 2-pack)
It is the natural partner in the Divide & Conquer: a half-moon deflector on the lower level of one half for indirect cooking and this griddle on the other for searing, two real zones without dismantling anything between stages. Note that it comes as a pack of two half-moons, so you can also cover the whole ring for long roasts. Stock comes and goes: if it is missing, any half-moon deflector declared for the Big Joe does the same job.

WMF BBQ Heat-Resistant Leather Gloves 40 cm (Pair)
A 6.35 kg cast iron half-moon is not moved with tongs or a tea towel. To flip it to the ribbed face or lift it out hot through the mouth of the Big Joe you need leather gloves that cover the forearm. These, at 40 cm, cover the forearm; check the temperature their listing declares before reaching in next to the charcoal.

Weber Cast Iron Protector 17889, 200 ml fine-mist spray
The listing does not declare whether the griddle comes seasoned, and in any case cast iron wants a film of grease after every wash to keep rust away. A spray made for cast iron, like this 200 ml one, is the convenient way to lay that thin coat over both faces and into the grooves of the ribbed face, where a brush leaves gaps.

FAQ
Will it fit my Kamado Joe Classic or a Big Green Egg Large?
No. It measures 60.96 x 30.48 cm, exactly half of a 24-inch grate, and is declared only for Big Joe I, II and III. On a Classic Joe or a BGE Large, at 46 cm, there is no way to seat it; for those the same griddle exists in a Classic version, in our catalogue as the Half Moon Griddle Classic. If your kamado is a Big Green Egg XL, at around 61 cm, measure first: the listing does not mention it and the Egg does not use the Divide & Conquer rack.
What is the difference between the smooth face and the ribbed face?
The smooth face is a griddle: full contact with the food, ideal for pressing a smash burger, cooking cuttlefish, eggs or chopped vegetables that would fall between the bars of a grate. The ribbed face works like a cast iron grate: the ridges leave sear marks, fat runs into the channels and the food does not stew in its own juices. You switch faces by flipping the plate when cold or, if hot, by lifting it out of the kamado first with serious gloves: it is 6.35 kg of iron, and the fat pooled in the grooves will flare if tipped onto the coals.
How do you season and clean a cast iron griddle?
The listing does not say whether it comes seasoned, so treat it as though it does not: wash it, dry it completely, spread a very thin coat of oil over both faces and heat it in the kamado until it stops smoking. After each use, scrape off the residue while hot, let it cool until you can handle it in a glove and only then rinse with water and no harsh soap: cold water on searing-hot cast iron can crack it. Dry it immediately on the still-warm kamado and oil it again. No dishwasher and never leave it wet: bare iron rusts overnight, and faster still in a coastal home.
Do I need anything else to use it on the Big Joe?
You need the Divide & Conquer rack, which is the Big Joe's multi-level system and where this half-moon sits; the listing mentions no handles or legs. If your Big Joe came with it as standard, you need nothing else to get started. Beyond that, it is worth having leather or aramid gloves to handle 6.35 kg of hot iron, and a spray or oil for seasoning. If you want the other half indirect, a half-moon deflector for the Big Joe completes the two-zone set-up.
