Basics.

n everyday usage, a vegetable is any part of a plant that is consumed by humans as food as part of a savory meal. The term "vegetable" is somewhat arbitrary, and largely defined through culinary and cultural tradition. It normally excludes other food derived from plants such as fruits, nuts and cereal grains, but includes seeds such aspulses. The original meaning of the word vegetable, still used in biology, was to describe all types of plant, as in the terms "vegetable kingdom" and "vegetable matter".

Originally, vegetables were collected from the wild by hunter-gatherers and entered cultivation in several parts of the world, probably during the period 10,000 BC to 7,000 BC, when a new agricultural way of life developed. At first, plants which grew locally would have been cultivated, but as time went on, trade brought exotic crops from elsewhere to add to domestic types. Nowadays, most vegetables are grown all over the world as climate permits, and crops may be cultivated in protected environments in less suitable locations. China is the largest producer of vegetables, and global trade in agricultural products allows consumers to purchase vegetables grown in faraway countries. The scale of production varies from subsistence farmers supplying the needs of their family for food, to agribusinesses with vast acreages of single-product crops. Depending on the type of vegetable concerned, harvesting the crop is followed by grading, storing, processing and marketing.

Vegetables can be eaten either raw or cooked and play an important role in human nutrition, being mostly low in fat and carbohydrates, but high in vitamins, minerals and fiber. Many governments encourage their citizens to consume plenty of fruit and vegetables, five or more portions a day often being recommend

Sweets were fed to the gods in ancient Mesopotamia^[6]:6 and India^[6]:16 and other ancient civilizations.^[7] Dried fruit and honey were likely the first sweeteners used in most of the world, but the spread ofsugarcane around the world was essential to the development of dessert.^[6]:13

Sugarcane was grown and refined in India before 500 BCE^[6]:26 and was crystallized, making it easy to transport, by 500 CE. Sugar and sugarcane were traded, making sugar available to Macedonia by 300 BCE and China by 600 CE. In South Asia, the Middle East and China, sugar has been a staple of cooking and desserts for over a thousand years. Sugarcane and sugar were little known and rare in Europe until the twelfth century or later, when the Crusades and thencolonialization spread its use.

Europeans began to manufacture sugar in the Middle Ages, and more sweet desserts became available.^[8] Even then sugar was so expensive usually only the wealthy could indulge on special occasions. The first apple pie recipe was published in 1381.^[9] The earliest documentation of the term cupcake was in "Seventy-five Receipts for Pastry, Cakes, and Sweetmeats" in 1828 in Eliza Leslie's Receipts cookbook.^[10]

The Industrial Revolution in America and Europe caused desserts (and food in general) to be mass-produced, processed, preserved, canned, and packaged. Frozen foods became very popular starting in the 1920s when freezing emerged. These processed foods became a large part of diets in many industrialized nations. Many countries have desserts and foods distinctive to their nations or region.^[11]

Cheese is a food derived from milk that is produced in a wide range of flavors, textures, and forms by coagulation of the milk protein casein. It comprises proteins and fat from milk, usually the milk of cows, buffalo, goats, or sheep. During production, the milk is usually acidified, and adding the enzyme rennet causes coagulation. The solids are separated and pressed into final form.^[1] Some cheeses have molds on the rind or throughout. Most cheeses melt at cooking temperature.

Hundreds of types of cheese from various countries are produced. Their styles, textures and flavors depend on the origin of the milk (including the animal's diet), whether they have been pasteurized, the butterfat content, the bacteria and mold, the processing, and aging. Herbs, spices, or wood smoke may be used as flavoring agents. The yellow to red color of many cheeses, such as Red Leicester, is produced by adding annatto. Other ingredients may be added to some cheeses, such as black pepper, garlic, chives or cranberries.

For a few cheeses, the milk is curdled by adding acids such as vinegar or lemon juice. Most cheeses are acidified to a lesser degree by bacteria, which turn milk sugars into lactic acid, then the addition of rennet completes the curdling. Vegetarian alternatives to rennet are available; most are produced by fermentation of the fungus Mucor miehei, but others have been extracted from various species of the Cynara thistle family. Cheesemakers near a dairy region may benefit from fresher, lower-priced milk, and lower shipping costs.
