Is Brass Safe for Cooking? What to Cook, What to Avoid
Brass cookware is fine for frying, boiling and dry dishes, and needs a tin lining (kalai) for sour or salty food. What to cook and what to avoid.
Yes, brass is safe for cooking when it is used the traditional way. Unlined brass is fine for frying, boiling and dry dishes; sour or salty food needs a vessel with a tin lining (kalai), and cooked food should not be stored in brass. That is the whole rule. The rest of this guide is the detail.
The short answer
- Frying, boiling, dry roasting, rice: unlined brass is fine.
- Tomato, tamarind, curd, lemon, vinegar: only in brass with intact kalai.
- Storage: do not keep cooked food in brass. Move it to steel or glass.
- Green spots inside: clean them off completely before the vessel is used again.
We make no health or nutrition claims for brass cookware in this guide. This is about using the metal correctly.
What reacts and why: sour and salty food
Brass is an alloy of copper and zinc. Acids react with both. The acids in everyday cooking come from tomato, tamarind, lemon, curd and vinegar. When they sit hot against bare brass, the food takes on a metallic, bitter taste and the surface of the vessel is attacked. Salt adds to the effect, most of all when salty food is left standing.
Fats, plain water, milk and dry grains do not react in this way during normal cooking. That is why the line falls where it does.
Safe without kalai: deep frying, boiling water or milk, dry roasting, rice
A heavy brass kadhai holds heat steadily, which is why halwais use one for frying. Unlined brass suits:
- Deep frying puri, pakora, jalebi and namkeen.
- Boiling water or milk.
- Dry roasting sooji, besan, peanuts or spices.
- Cooking plain rice.
Empty the vessel once you are done. Do not leave oil or milk sitting in it overnight.
Needs kalai: curries with tomato, tamarind, curd, lemon
Kalai is a thin layer of tin wiped onto the inside of the hot vessel. It is the traditional barrier between sour food and brass. The inside of a tinned kadhai looks silvery or soft grey, not yellow.
| Dish | Unlined brass | Brass with intact kalai |
|---|---|---|
| Puri, pakora, deep frying | Yes | Yes, with oil in before heating |
| Boiled water, milk, plain rice | Yes | Yes |
| Tomato gravy, sambar, rasam | No | Yes |
| Kadhi, curd curries | No | Yes |
| Pickles, chutneys, anything with vinegar or lemon | No | Cook, then transfer at once |
Two cautions with kalai. Tin melts at about 232°C, so never heat a tinned vessel empty. And tin wears with use, so when yellow metal shows through the lining, re-tin before cooking sour food in it again. Both are explained in kalai explained.
Do not store cooked food in brass
Cooking takes minutes. Storage takes hours, and that is when reactions have time to happen. Once the meal is served, move leftovers to steel or glass. This applies to tinned vessels as well, since any thin spot in the lining is exposed for longer. It applies most of all to dal, curries, pickles and anything salted.
Serving plates, glasses and lotas
Serving is different from cooking and storing. Food sits on a brass thali for the length of a meal and is then washed off. Dry and mild foods such as roti, rice, sabzi and sweets are served on brass in many homes. Keep pickle, lemon wedges and curd in a separate steel or glass katori.
Plain drinking water in a brass glass or lota is traditional. Use it for short periods and rinse the vessel daily. Avoid juices, lassi, chaas and lemon water in brass. Our glasses and the wider serveware range, 570 pieces in all, are listed with their material so you can see what is brass, copper or steel.
Care that keeps it safe
- Wash soon after use and dry at once. Brass left wet goes green.
- If green spots (verdigris) appear inside, scrub them off completely and rinse well before using the vessel for food or water. See why brass turns black or green.
- Inside a tinned vessel: soft sponge and dish soap only. No steel wool, lemon or tamarind.
- Outside: lemon and salt or Pitambari, as in the Hindi guide पीतल के बर्तन कैसे साफ करें.
- Check the lining every few months and re-tin when brass shows through.
Our cookware range has 67 pieces, including brass kadhai with kalai from 1 to 3.5 litre. A brass utensil is also a common Dhanteras purchase; see Dhanteras gifts.
