General information:
From Wikipedia: “Vanilla is a flavoring derived from orchids of the genus Vanilla, primarily from the Mexican species, flat-leaved vanilla (V. planifolia). The word vanilla, derived from the diminutive of the Spanish word vaina (vaina itself meaning sheath or pod), is translated simply as "little pod". Pre-Columbian Mesoamerican people cultivated the vine of the vanilla orchid, called tlilxochitl by the Aztecs. Spanish conquistador Hernán Cortés is credited with introducing both vanilla and chocolate to Europe in the 1520s. ...
Vanilla is the second-most expensive spice after saffron, because growing the vanilla seed pods is labor-intensive. Despite the expense, vanilla is highly valued for its flavor. As a result, vanilla is widely used in both commercial and domestic baking, perfume manufacture, and aromatherapy.”
Cultivars:
“Bourbon vanilla or Bourbon-Madagascar vanilla, produced from V. planifolia plants introduced from the Americas, is the term used for vanilla from Indian Ocean islands such as Madagascar, the Comoros, and Réunion, formerly the Île Bourbon. It is also used to describe the distinctive vanilla flavor derived from V. planifolia grown successfully in tropical countries such as India.
Mexican vanilla, made from the native V. planifolia, is produced in much less quantity and marketed as the vanilla from the land of its origin. Vanilla sold in tourist markets around Mexico is sometimes not actual vanilla extract, but is mixed with an extract of the tonka bean, which contains coumarin. Tonka bean extract smells and tastes like vanilla, but coumarin has been shown to cause liver damage in lab animals and is banned in food in the US by the Food and Drug Administration since 1954.
Tahitian vanilla is the name for vanilla from French Polynesia, made with V. tahitiensis. ...
West Indian vanilla is made from V. pompona grown in the Caribbean and Central and South America.”
Artificial vanilla:
“Most artificial vanilla products contain vanillin, which can be produced synthetically from lignin, a natural polymer found in wood. Most synthetic vanillin is a byproduct from the pulp used in papermaking, in which the lignin is broken down using sulfites or sulfates. However, vanillin is only one of 171 identified aromatic components of real vanilla fruits.
The orchid species Leptotes bicolor is used as a natural vanilla replacement in Paraguay and southern Brazil.”
Nonplant vanilla flavoring:
“In the United States, castoreum, the exudate from the castor sacs of mature beavers, has been approved by the Food and Drug Administration as a food additive, often referenced simply as a "natural flavoring" in the product's list of ingredients. It is used in both food and beverages, especially as vanilla and raspberry flavoring, with a total annual U.S. production of less than 300 pounds. It is also used to flavor some cigarettes and in perfume-making, and is used by fur trappers as a scent lure.”
Culinary uses:
“The four main commercial preparations of natural vanilla are:
- Whole pod
- Powder (ground pods, kept pure or blended with sugar, starch, or other ingredients)
- Extract (in alcoholic or occasionally glycerol solution; both pure and imitation forms of vanilla contain at least 35% alcohol)
- Vanilla sugar, a packaged mix of sugar and vanilla extract
Vanilla flavoring in food may be achieved by adding vanilla extract or by cooking vanilla pods in the liquid preparation. A stronger aroma may be attained if the pods are split in two, exposing more of a pod's surface area to the liquid. In this case, the pods' seeds are mixed into the preparation. Natural vanilla gives a brown or yellow color to preparations, depending on the concentration. Good-quality vanilla has a strong, aromatic flavor, but food with small amounts of low-quality vanilla or artificial vanilla-like flavorings are far more common, since true vanilla is much more expensive.
Regarded as the world's most popular aroma and flavor, vanilla is a widely used aroma and flavor compound for foods, beverages and cosmetics, as indicated by its popularity as an ice cream flavor. Although vanilla is a prized flavoring agent on its own, it is also used to enhance the flavor of other substances, to which its own flavor is often complementary, such as chocolate, custard, caramel, coffee, and others. Vanilla is a common ingredient in Western sweet baked goods, such as cookies and cakes.
The food industry uses methyl and ethyl vanillin as less-expensive substitutes for real vanilla. Ethyl vanillin is more expensive, but has a stronger note. Cook's Illustrated ran several taste tests pitting vanilla against vanillin in baked goods and other applications, and to the consternation of the magazine editors, tasters could not differentiate the flavor of vanillin from vanilla; however, for the case of vanilla ice cream, natural vanilla won out. A more recent and thorough test by the same group produced a more interesting variety of results; namely, high-quality artificial vanilla flavoring is best for cookies, while high-quality real vanilla is slightly better for cakes and significantly better for unheated or lightly heated foods. The liquid extracted from vanilla pods was once believed to have medical properties, helping with various stomach ailments.”
