The Copper Pot (Nhas): Its Revival in Moroccan Kitchens
Walk the metalworkers' souk in Fez or Marrakech and the ring of hammer on copper still fills the air. Copper — nhas — was once the aristocrat of the Moroccan kitchen, prized for the way it answers instantly to heat, and for the beauty of a hand-hammered surface. Cheap aluminium and steel pushed it aside for daily cooking, but a revival is under way, driven by both cooks who value its performance and buyers who value the craft.

- Copper responds to heat faster than any other cookware metal, giving precise control.
- Cooking copper must be lined — traditionally tinned — because bare copper is reactive with food.
- It excels at sugar work and preserves, where its responsiveness prevents scorching.
Why copper cooks so well
Copper conducts heat roughly twice as fast as aluminium and many times faster than stainless steel, and just as importantly it responds instantly when you change the flame. Turn the heat down and a copper pan cools almost at once; turn it up and it follows. For a cook that means real, immediate control — the difference between a sauce that catches and one you rescue in time. This is why professional kitchens the world over still reach for copper for delicate work.
In the Moroccan tradition, copper's responsiveness suited the careful reduction of syrups for pastries, the cooking of jams and fruit pastes, warm milk and tea water, and the gentle work of confectionery. Grand Fassi households kept whole batteries of hammered copper, much of it as much for display and status as for the stove, gleaming on kitchen walls.
The lining question and safety
Bare copper reacts with acidic and salty foods, which can taint flavour and is not something you want leaching into every meal. That is why cooking copper is lined: traditionally with a thin coat of tin applied by the same craftsmen who hammer the pots, and in some modern pieces with stainless steel. The one classic exception is a copper preserving or sugar pan used unlined for jam, where the high sugar concentration and short contact time make it safe and where bare copper actually helps the set.
If you buy an antique or souk copper pot to cook in, check the lining. Worn tin that shows copper through the base needs re-tinning — a service the coppersmiths still offer — before you use it for food. A great deal of the copper sold to visitors is decorative: trays, ewers and lidded pots meant for looking at, not cooking in. Know which you are buying, and treat purely decorative pieces as tableware and ornament.
- Tinned lining: the traditional food-safe surface; have it re-done when it wears through.
- Unlined only for jam: a dedicated sugar pan is the sole safe unlined use.
- Decorative vs cooking: most tourist copper is ornamental — confirm before cooking in it.
What to cook in nhas, and caring for it
Play to copper's strengths: syrups and sugar for pastries such as chebakia and sellou binders, fruit jams and quince or fig pastes, warm-milk desserts, and any sauce where precise, responsive heat matters. It is less suited to long, unattended braises — a clay tagine or heavy stockpot does that better — and its thin tin lining dislikes very high, empty heat, which can melt tin.
Copper tarnishes to a warm brown and needs occasional polishing to shine, traditionally with a paste of lemon, salt and a little flour or vinegar. Cook over gentle to moderate heat, never scour a tinned interior with harsh abrasives, and hand-wash and dry it. Cared for, a good copper pot outlives its owner — part of the reason the craft, and the pots, are being rediscovered by a new generation.
Frequently asked questions
Is it safe to cook in Moroccan copper pots?
Yes, provided the pot is lined — traditionally with tin — so food never touches bare copper. Bare copper reacts with acidic and salty foods and should not be used for everyday cooking. The one exception is an unlined copper sugar pan used for jam, where high sugar concentration and brief contact make it safe. Always check an old pot's lining and have worn tin re-coated.
Why is copper cookware so expensive?
Genuine hand-hammered, properly lined copper is labour-intensive to make: the metal is costly, the hammering and tinning are skilled handwork, and good pieces are thick and heavy. You are paying for both performance and craft. Much cheaper copper on sale is thin, decorative and not meant for cooking, so a low price usually signals an ornamental piece rather than real cookware.
What is copper best for in Moroccan cooking?
Anything that rewards fast, precise, responsive heat: sugar syrups and confectionery, fruit jams and pastes, warm-milk desserts, and delicate sauces that scorch easily in slower pans. Its instant response prevents the catching and crystallising that ruin sugar work. It is less suited to long unattended braises, which clay or a heavy stockpot handle better.
How do I clean and maintain a copper pot?
Hand-wash it and dry it promptly, and never scour a tinned interior with harsh abrasives that strip the lining. The exterior tarnishes naturally and can be polished with a traditional paste of lemon, salt and a little flour or vinegar when you want it to shine. Cook over gentle to moderate heat and avoid heating a tinned pan empty, as extreme heat can damage the tin.
