The local cuisine of Punjab is heavily influenced by the agriculture and farming lifestyle prevalent from the times of the ancient Indus Valley civilization. Dishes similar to tandoori chicken may have existed during the Harappan civilization during the Bronze Age of India. According to the archeologist Professor Vasant Shinde, the earliest evidence for a dish similar to tandoori chicken can be found in the Harappan civilization and dates back to 3000 BC. His team has found ancient ovens at Harappan sites which are similar to the tandoors that are used in the state of Punjab. Physical remains of chicken bones with char marks have also been unearthed.<ref>Template:Cite journal</ref><ref>Template:Cite web</ref><ref name="eco">Template:Cite news</ref> Harappan houses had keyhole ovens with central pillars which were used for roasting meats and baking breads.<ref>Template:Cite web</ref> Sushruta Samhita records meat being cooked in an oven (kandu) after marinating it in spices like black mustard (rai) powder and fragrant spices.<ref>Template:Cite web</ref> According to Ahmed (2014), Harappan oven structures may have operated in a similar manner to the modern tandoors of the Punjab.<ref>Template:Cite book</ref>
There are many styles of cooking in Punjab. In the villages many people still employ the traditional methods and equipment for cooking purposes. This includes wood-fired and masonry ovens. Modern methods include cooking on gas cookers. Tandoori style of cooking involves use of the tandoor.<ref>Template:Cite news</ref> In India, tandoori cooking is traditionally associated with Punjab<ref>[1] The Rough Guide to Rajasthan, Delhi and Agra By Daniel Jacobs, Gavin Thomas</ref> as Punjabis embraced the tandoor on a regional level.<ref>Template:Cite web</ref> This style of cooking became popular throughout India after the 1947 partition when Punjabis resettled in places such as Delhi. According to Planalp (1971), "the Panjab-style underground oven known as tandur is becoming increasingly popular in New Delhi" pointing to the Punjabi style of the tandoor.<ref>Planalp, Jack M. (1971) Heat Stress and Culture in North India.

Punjab is a major producer of wheat, rice and dairy products. These products also form the staple diet of the Punjabi people. The state of Punjab has one of the highest capita usage of dairy products in India.<ref>Times of India Template:Cite web</ref> Therefore, dairy products form an important component of Punjabi diet.
Dairy products are a staple in Punjabi cuisine.<ref>Template:Cite book</ref> Both cow milk and water buffalo milk are popular. Milk is used for drinking, to add to tea or coffee, to make homemade dahi (yogurt), for butter and making traditional Punjabi cottage cheese called paneer.<ref>Template:Cite book</ref> Traditionally, yogurt is made every day using the previous day's yogurt as the starting bacterial culture to ferment the milk. Curd is used as dressing for many raita dishes, to prepare kadhi, to prepare cultured buttermilk (chaas), and as a side dish in a meal.<ref>Misra, R., 2011.

Tandoor
Template:Further
According to Ancient Pakistan - An Archaeological History by Mukhtar Ahmed,<ref>Ahmed, Mukhtar (2014) Ancient Pakistan - An Archaeological History: Volume IV: Harappan Civilization - Theoretical and the Abstract. Amazon. [6]</ref> Harappan oven structures may have operated in a similar manner to the modern tandoors of the Punjab. The tandoor is traditionally made of clay and is a bell-shaped oven, set into the earth and fired with wood or charcoal reaching high temperatures. According to Roy Hayter<ref>Hayter, Roy (1992) Food Preparation and Cooking: Levels 1 & 2. Macmillan International Higher Education,[7]</ref> the original versions of the tandoor "in the Punjab, a province in the north-west of India, were sunk neck deep in the ground". He further states that modern versions can also rest above the ground.
Etiquette of eating is considered a major part of the cuisine. Every Punjabi household follows certain regional etiquette. The word etiquette has many local names depending on the particular region of Punjab. Though certain etiquette varies regionally, there are many etiquette practices that are common throughout Punjab. Communal dining is a norm in Punjabi families.
Bringing and sending fresh fruits, sweets and food items as gifts to family members is a common practice in Punjab, particularly during the spring season. Food items are distributed among neighbors as well on special occasions and as a sign to show hospitality. Mango is considered a delicacy and produced widely in Punjab,<ref name="TRTA Pakistan Mangoes">Template:Cite web</ref> and mango parties are common during the fruit's harvest season. Watermelon and radish at food stalls are shared among friends and relatives.
An invitation to a meal or tea is typically distributed few days beforehand. Denying the invitation for no major reason is considered a breach of etiquette.
Table setting is done before the arrival of the guests.
Family members or any occupants within one home make sure to eat together during the dinner. If any other person is present in the vicinity, then they are offered meals as a way of giving respect. It is considered rude to start eating food without asking others to participate in a meal. It is customary to offer food to anyone in your vicinity before eating. The invited guest or elder person is given special respect and attention. Usually the invited guest is requested to start the meal. It is considered rude if the host starts eating without taking into account the attendance of all guests.
Punjabi families use a hybrid style of South Asian and European utensil etiquette most of the time. The bread and rice are eaten with the hands. Desserts are eaten with spoons. Soup spoons are used for consuming soup and forks are used for eating noodles. Chewing food with one's mouth open and burping in front of others is considered rude. In the villages of Punjab, an additional common plate is usually placed on the table for any bones left from the consumption of bone meat. Placing leftovers on the floor or on the table floor is considered bad etiquette.
The roadsides often serve as suburban eatery centers. They can also be a communal place to sit and chat. Some serve on the same concept of the greasy spoon.
Punjabi cuisine has spread internationally. Punjab in London has been family-run since 1946 and is the UK's oldest North Indian restaurant.<ref>Template:Cite web</ref> The New Punjab Club,<ref>Template:Cite web</ref> located in Hong Kong, became the world's first Punjabi restaurant to earn one Michelin star in 2019.<ref>Template:Cite web</ref>
