Couscous steamer
A two-part steamer for couscous: a perforated upper chamber sits over a lower pot that produces steam. Clay, basketry and metal forms are documented in different places and periods.

Tanjia jar
A purpose-made terracotta vessel, also called tangia or kallouch, for Marrakech’s slow-cooked tanjia. Potters make it mainly in Marrakech; a fernatchi cooks the closed jar among managed furnace embers.
A jar with the dish’s name
Tangia names both the meal and the vessel used to cook it. A 2021 World Intellectual Property Organization study calls the jar tangia or kallouch and describes it as a terracotta amphora specially designed for the dish. It says the jar is mainly produced in Marrakech and uses the same terracotta as tagines. In a recent account of the city’s practice, a visitor buys an unglazed clay urn from a potter. The jar’s exact capacity and dimensions are not supplied in these sources.
The WIPO study suggests that the familiar cooking vessel may have developed from an amphora used for carrying and storing liquids. It presents this as an apparent evolution, not a securely dated sequence. The documented vessel is best understood through its current form and use rather than an asserted antiquity. It is distinct from the shallow dish and conical lid called a tagine: the tangia is a jar that can be closed and placed among embers.
From the potter to the hammam furnace
The jar connects craft production with shared city infrastructure. In Marrakech, the WIPO study records terracotta tangias made mainly in the city. For cooking, meat and seasonings are placed inside, the mouth is covered with paper secured by wire, and the vessel is set in wood-fire embers under the supervision of the fernatchi, the furnace attendant. A recent Smithsonian account describes the urn placed in residual embers beneath the wood-fired furnace that heats a hammam. The attendant manages the heat; the jar does not generate it.
That arrangement lets a household use heat already maintained for the bathhouse rather than fire a separate oven. The vessel contains the food while surrounding embers provide slow heat. The documented Marrakech recipe places the jar in managed ashes beside the furnace rather than directly in the fire, with the attendant redistributing and replenishing ash. This is a cooking vessel for braising, not evidence of pressure cooking or room-temperature preservation.
A place-bound, fragile form
The strongest documented association is with Marrakech, Morocco: the WIPO study links both production and the named dish to the city, and the official tourism council presents tanjia as a signature local specialty. These accounts support local manufacture and traditional use; they do not establish that every jar is made there or supply a first date for the practice.
Terracotta is the jar’s defining material and a practical limit: the WIPO study explicitly calls the utensil fragile. It supplies no standard capacity, measurements, cleaning method or seasoning instructions, so these details should come from the maker of an individual vessel rather than be assumed from another pot. Its relation to the recipe is recorded in the linked Tanjia marrakchia page.
History
A 2021 WIPO study identifies a purpose-made terracotta tangia, also called kallouch, mainly produced in Marrakech. It cautiously suggests that the cooking jar developed from an amphora used to transport and store liquids, but gives no date for the change. Contemporary use is reported in 2026. This supports continued use, not an invention date.
Equipment details
CapacityNo inspected source gives a capacity.
SizeNo inspected source gives dimensions.
PowerNo power The vessel is passive; its documented heat comes from wood-fire embers managed by the furnace attendant.
How you get oneBought from a maker The WIPO study says the jar is mainly produced in Marrakech; a 2026 account describes a local potter selling an unglazed example.
CareA WIPO study identifies the terracotta utensil as fragile but gives no cleaning, seasoning or storage protocol. Ask the maker about care for the individual jar.
Made of
- Terracotta (fired clay) — Vessel body
The 2021 WIPO study says it is the same terracotta used for tagines. A 2026 account describes a contemporary unglazed example; glaze is not asserted for all tangias.
Limits
The terracotta jar is described as fragile.

Scoping study on the gastronomic tourism sector in MoroccoThe tangia or kallouch jar is purpose-made from terracotta, mainly produced in Marrakech, using terracotta also used for tagines.
The study cautiously suggests evolution from a liquid-transport and storage amphora, without dating it.
The study describes the jar as fragile and documents paper closure and cooking in embers supervised by the fernatchi.
