Dal

In Indian cuisine, dal (also spelled daal or dhal pronunciation: [d̪aːl]), parippu, pappu, or paruppu are dried, split pulses (e.g., lentils, peas, and beans) that do not require soaking before cooking. India is the largest producer of pulses in the world. The term is also used for various soups prepared from these pulses. These pulses are among the most important staple foods in South Asian countries, and form an important part of the cuisines of the Indian subcontinent.
The word dāl (dal) derives from the Sanskrit verbal root dal- "to split", which is inherited from Proto-Indo-European *delh₁- "to split, divide".
Lentils are among the most ancient cultivated foods; they have been found in human settlements dating back to the Bronze Age. Researchers have dated the preparation and cooking of split dal as far back as 800-300 BC.
Dal as a staple food has been mentioned in many ancient religious texts, including the Yajurveda, the Mahayana Buddhist Laṅkāvatāra Sūtra, and the Bible:
Dal are often prepared in three different forms:
The hulling of a pulse is intended to improve digestibility and palatability. It also affects the nutrition provided by the dish, significantly increasing protein and reducing dietary fibre content. Pulses with their outer hulls intact are also quite popular in the Indian subcontinent as the main cuisine. Over 50 different varieties of pulses are known in the Indian subcontinent.
Dal is frequently eaten with flatbreads, such as rotis or chapatis, or with rice. The latter combination is called dal bhat in Nepali, Gujarati, and various other Indian languages. In addition, certain types of dal are fried, salted, and eaten as a dry snack, and a variety of savory snacks are made by frying a paste made from soaked and ground dals in different combinations, to which other ingredients, such as spices and nuts (commonly cashews) may be added.
Dal preparations are eaten with rice, chapati and naan on the Indian subcontinent. The manner in which it is cooked and presented varies by region. In South India, dal is often called "paruppu". It is primarily used to make a dish called sambar. It is also used to make parippu that is mixed with charu and rice. Ground chana dal is used to make a paste called besan, which is used in the preparation of many dishes including bhaji and Mediterranean dishes like farinata.
Most dal recipes are quite simple to prepare. The standard preparation begins with boiling a variety of dal (or a mix) in water with some turmeric, salt to taste, and then adding a fried garnish at the end of the cooking process. In some recipes, tomatoes, kokum, unripe mango, jaggery, or other ingredients are added while cooking the dal, often to impart a sweet-sour flavour.
The fried garnish for dal goes by many names, including chaunk, tadka/tarka, bagar, fodni, and phoran. The ingredients in the chaunk for each variety of dal vary by region and individual tastes. The raw spices (more commonly cumin seeds, mustard seeds, asafoetida, and sometimes fenugreek seeds and dried red chili pepper) are first fried for a few seconds in the hot oil on medium/low heat. This is generally followed by ginger, garlic, and onion, which are generally fried for 10 minutes. After the onion turns golden brown, ground spices (turmeric, coriander, red chili powder, garam masala, etc.) are added. The chaunk is then poured over the cooked dal.
As the main ingredient of dal is the pulse used, it gains much of its nutritional properties from the pulse.
