History and origin of baking powder

Baking is not usually thought of as a chemical industry, but it relies on the interactions of the various chemicals in flour and the other substance used and thus is chemically based.

Leavening was practiced by the Eygptians, and the practice was handed down by them to the Greeks and by the Greeks to the Romans.

From the time of the Romans to the present, the use of leavening has been common. In the early days leavening was ordinarily accomplished by growing yeast or yeasts in a dough or batter rich in carbohydrates.

The mixing of baking soda and cream of tartar marked the introduction of baking powder. But the two chemicals had to be kept in separate containers until used, or else they would react if any moisture was present. And because cream of tartar was imported from France, there were the additional problems of supply and expense.

During the 1860s, various companies introduced other ingredients in their baking soda formulas and sold them as baking powders. These ingredients behaved in a more controlled way in recipes. Over time, different carbonate and acid mixtures have been sold as baking powders. Today, sodium bicarbonate and tartaric acid mixtures remain the most popular.

Before baking powder, there were mainly two ways used to make biscuits or bread light and fluffy. The first way was to add small air bubbles into the dough by beating it with a spoon or a whisk, like you would whip up whipped cream.

The second way, which is still used for most breads, is to add yeast. Yeast are microorganisms that digest sugars and produce carbon dioxide, which then forms bubbles in the dough. The development of baking powder introduced a third path to leavening dough.

Baking powder is a mixture of baking soda, starch, and at least one slightly acidic compound such as cream of tartar that works as a leavening agent in baking by releasing carbon dioxide when mixed with a liquid, such as milk or water.

It is a solid mixture that is used as a chemical leavening agent in baked goods. Baking powder is a combination of baking soda and an acid. When you add baking powder to water or milk, the alkali and the acid react with one another and produce carbon dioxide bubbles.

Tamarind

Native to tropical Africa, the large evergreen tamarind tree spread to India in prehistoric times and now grows in the tropical and subtropical regions of the world. The tree is large, spreading tree, having very small, deep-green leaves.

Tamarind is a long curved, brown, tropical seed pod with a fruity sweet pulp. Tamarind pulp contains tartaric acid 5%, citric acid 4%, malic and acetic acids, tartaric of potassium 8%, inverts sugar 25 to 40%, gum and pectin.

It would have been the Arabs who first brought tamarind across the Persian Gulf from India, influencing the cooking of the southeast of Iran, the Gulf region, and Egypt.

Some of the best recipes using tamarind are found in the coastal regions of the Gulf, where it is often married with fenugreek, turmeric, or curry powder in delicious fish dishes, echoing the flavors of India.

Tamarind is also popular in Mexico and the Spanish-speaking Caribbean, where it’s used to flavor sauces, candies, and drinks. Tamarind

History of herbs

Long before humans began to cultivate their own crops, they hunted and foraged for food. Eventually they found that they could produce larger quantities of grain and vegetables through farming, but the plants that made their meals more interesting still grew in the rocky places that were unsuitable to cereal agriculture.

The plants that call ‘herbs’ continued to be hunted in the wild, - indeed in many parts of the world they still are. The legend tells that people learned about herbs by observing animals and how they reacted to various plants.

If eating a particular plant resulted in a certain behavior or physical change, such as lethargy, then it was thought the plants had caused its. It is also how poisonous plants were discovered.

60 000 years ago, Neanderthal man valued herbs as medicinal agents. The antiquity of the use of herbs can be deduced from oral traditions and legends transmitted by the shamans or medicine men or Eurosia and the Americas.

It seems probable that many of the flavoring herbs now in use were similarly employed before the erection of the pyramids and also that many then popular no longer appear in modern lists of esculents.

The Ebers Papyrus is the oldest written herbal known to exists, written about 1500 BC. It names more than one hundred and twenty-five pants with eight hundred and eleven prescriptions for salves, poultices, gargles, inhalations, enemas, suppositories, pills, liquid medicines and directions for fumigation.

In temperate regions, where most herbs have little pungency compared to those of Mediterranean or tropical climates, herbs added interest to an otherwise bland and monotonous diet, whether of cereals, roots or a little meat or fish.

Relying upon Biblical records alone, several herbs were highly esteemed prior to current era; in the gospels of Matthew and Luke reference is made to tithes of mint, anise, rue, cumin and other "herbs"; and, more than 700 years previously, Isaiah speaks of the sowing and threshing of cumin which, since the same passage (Isaiah xxviii, 25) also speaks of "fitches" (vetches), wheat, barley and "rie" (rye), seems then to have been a valued crop.

The Muslims, who arrived in eastern Asia in the 9th and 10th centuries, were probably responsible for the appearance of cloves in Zanzibar and Mombasa before the Portuguese arrived there, and would have contributed to the spread of Indonesians spices in the Middle East and Europe.

Later, specific plants that produced known effects were grown in monasteries and studied by both clergy and doctors.
