Ghee

Ghee is a type of clarified butter, originating from India. It is commonly used for cooking, as a traditional medicine, and for Hindu religious rituals.

Description
Ghee is typically prepared by simmering butter, which is churned from cream, skimming any impurities from the surface, then pouring and retaining the clear liquid fat while discarding the solid residue that has settled to the bottom. Spices can be added for flavor. The texture, color, and taste of ghee depend on the quality of the butter, the milk used in the process, and the duration of boiling time.

Etymology
The word ghee comes from घृत (, ) 'clarified butter', from घृ, ghṛ-, 'to sprinkle'; it is cognate with the Ancient Greek word χριστός (khristós, 'rubbed, anointed'), from which the English word Christ is derived.

In Hinduism
Traditionally, ghee is made from bovine milk, either cow or water buffalo. Ghee has been used in rituals since the Vedic period and it is a sacred requirement in Vedic yajña and homa (fire rituals), through the medium of Agni (fire) to offer oblations to various deities (See: Yajurveda).

Fire rituals are utilized for ceremonies such as marriage and funerals. Ghee is required in Vedic worship of mūrtis (divine deities), with aarti (offering of ghee lamp) called diyā or dīpa and for Pañcāmṛta (Panchamruta) where ghee along with mishri, honey, milk, and dahi (curd) is used for bathing the deities on the appearance day of Krishna on Janmashtami, Śiva (Shiva) on Mahā-śivarātrī (Maha Shivaratri). There is a hymn to ghee. In the Mahabharata, the Kaurava were born from pots of ghee.

Ghee is also used in bhang in order to heat the cannabis to cause decarboxylation, making the drink psychoactive.

In Buddhist scripture, stages of dairy production are used as metaphors for stages of enlightenment. The highest-stage product, sarpir-maṇḍa, is theorised to be ghee or clarified butter.

Culinary uses
Ghee is common in cuisines from the Indian subcontinent, including traditional rice preparations (such as biryani). In Maharashtra, polis or Indian flatbreads are accompanied with ghee. For example, 'Puranpoli', a typical Maharashtrian dish is eaten with much ghee. In Rajasthan, ghee often accompanies baati. All over North India, ghee tops roti. In Karnataka and Tamil Nadu, ghee tops dosa, and kesari bhath. In Bengal (both West Bengal and Bangladesh) and Gujarat, khichdi is a traditional evening meal of rice with lentils, cooked in a curry made from dahi (yogurt), cumin seeds, curry leaves, cornflour, turmeric, garlic, salt and ghee. It is also an ingredient in kadhi and Indian sweets, such as Mysore pak, and varieties of halva and laddu. Indian restaurants typically incorporate large amounts of ghee, sometimes brushing naan and roti with it, either during preparation or just before serving. In the state of Odisha ghee is widely used in regional Odia cuisines such as Khechedi and Dalma. Particularly the satwik type of food prepared in most temples in Odisha uses ghee as a major ingredient in their culinary tradition. Ghee is widely used in South Indian cuisine for tempering curries and in the preparation of rice dishes and sweets. South Indians have a habit of adding ghee to their rice before eating it with pickles and curries. South Indians are among the biggest consumers of ghee. The people from Andhra Pradesh especially use ghee for the preparation of savoury and sweet dishes alike. Ghee is important to traditional North Indian cuisine, with parathas, daals and curries often using ghee instead of oil for a richer taste. The type of ghee, in terms of animal source, tends to vary with the dish; for example, ghee prepared from cow's milk (গাওয়া ঘী, gaoa ghi) is traditional with rice or roti or as a finishing drizzle atop a curry or daal (lentils) whereas buffalo-milk ghee is more typical for general cooking purposes.

Ghee is an ideal fat for deep frying because its smoke point (where its molecules begin to break down) is 250 C, which is well above typical cooking temperatures of around 200 C and above that of most vegetable oils.

Flavor
The main flavor components of ghee are carbonyls, free fatty acids, lactones, and alcohols. Along with the flavor of milk fat, the ripening of the butter and the temperature at which it is clarified also affect the flavor. For example, ghee produced by the clarification of butter at 100 C or less results in a rich and mild flavor, whereas batches produced at 120 C produce a strong flavor.

Differences from clarified butter
Ghee differs slightly in its production from that of clarified butter. The process of creating clarified butter is complete once the water is evaporated and the fat (clarified butter) is separated from the milk solids. However, the production of ghee includes simmering the butter, which makes it nutty-tasting and aromatic.

A traditional Ayurvedic recipe for ghee is to boil raw milk and let it cool to 43 C. After leaving it covered at room temperature for around 12 hours, add a bit of dahi (yogurt) to it and leave it overnight. This makes more yogurt. This is churned with water, to obtain cultured butter, which is used to simmer into ghee.

Nutrition and health
Like any clarified butter, ghee is composed almost entirely of fat, 62% of which consists of saturated fats. Most commercial preparations in India were also found to contain significant amounts of trans fats. It has negligible amounts of lactose and casein and is, therefore, acceptable to most people who have a lactose intolerance or milk allergy.

There are mixed opinions about whether ghee consumption is associated with an increased risk of cardiovascular disease. The British Dietetic Association, British Nutrition Foundation, National Health Service, Heart and Stroke Foundation of Canada and World Health Organization advise people to limit ghee consumption due to its high saturated fat content.

Preparation methods
There are five common methods through which ghee is prepared. Industrial preparation on the other hand is done by using "white butter", usually sourced from other dairies and contractors.



Milk butter
Sour raw milk is churned into butter. The butter is boiled in an open pan to allow the water to evaporate. The hot ghee is transferred and stored.

Direct cream
Fresh cream, cultured or washed cream is directly converted to ghee. This method requires a long heating time and produces a caramelized flavor.

Cream butter
Milk is separated into cream which is then churned into butter. The butter undergoes heat clarification to produce ghee.

Pre-stratification
This method is suitable for large quantities of butter. Butter is melted at 80 - 85 C for 30 minutes. Layers of protein particles, fat and buttermilk are induced. The buttermilk is drained out. The remaining layers of fat are heated to a temperature of 110 C to remove moisture and develop flavor.

Packaging
Ghee is generally found to be packaged in airtight glass jars. They should be kept away from direct sunlight as sunlight can cause moisture to build inside the jar. Moisture can cause deterioration to the ghee's quality as well as reduce its shelf life. To prevent the acceleration of the oxidation process, they should be protected from anything that causes it, such as UV rays from sunlight and fluorescent lights. If the jar is unopened, it does not need to be refrigerated as long as the previously mentioned conditions are met. Once opened, they can be stored in a kitchen cabinet for up to three months. Afterwards, it may be left in the refrigerator for up to a year. The refrigerator causes ghee to harden but if it is left at room temperature for a while, it will soften up again.

Composition
Ghee may be made of milk from various domesticated ungulates, such as cows, buffaloes and sheep. The composition of ghee varies depending on the animal whose milk has been used. The vitamin A content ranged from 315 to 375 μg per 100 grams. Palmitic acid and oleic acid were two of the main fatty acids found in both cow and sheep ghee. The saturated fatty acid profile was 53.9 to 66.8%, the unsaturated fatty acid profile was 22.8 to 38.0% and the other fatty acids was 3.5 to 10.4%. Cholesterol amounts ranged from 252 to 284 mg/100 grams.

Market
The market size of ghee in India is 10,000 crore rupees or US$1.5 billion as of 2016. India is the world's largest producer of buffalo and cow milk and consequently also the largest producer and consumer of ghee.
