Dear Allison, Since I love to cook, I enjoyed researching a response to your question, “What is the origin of vanilla and what is the difference between artificial vanilla and vanilla extract?” Vanilla originated from an orchid plant native to Mexico called Vanilla Fragrans, also known as Vanilla planifolia. A long slender pod or bean is produced from the flower of the plant. It is picked green and undergoes a curing and drying process before being made into vanilla extract. Vanillin, a crytal-like substance produced during the curing process adds to the flavor and aroma of the extract. Unfortunately, vanilla extract from Mexico can have tonka bean extract added. The tonka bean extract smells like vanilla, but contains coumarin, a substance banned by the US Food and Drug Administration (FDA) as a food additive after studies showed a link between coumarin and liver and other organ damage. One Internet source (http://soar.berkeley.edu/recipes/hints/recipe73.rec link defunct as of 7/20/2006) mentioned that the explorer Cortez of Spain discovered the vanilla bean in Mexico and brought it back to Spain. Its use spread throughout Europe from there. In 1873 the vanilla plant was introduced to Madagascar. Madagascar and Indonesia are now the world’s leading producers of vanilla beans. Pure vanilla extract is produced when the vanilla bean pods and seeds are chopped and soaked in alcohol. Time enhances the flavor and aroma of pure vanilla extract. Artificial vanilla flavoring is made from eugenol (derived from clove stem oil) or acid hydrolysis of lignin (wood pulp). This compound is mixed with real vanilla to make vanillin. Ninety percent of vanilla flavoring used in US food manufacturing is artificial vanillin. One ounce of artificially produced vanillin has roughly the same flavoring power as one gallon of natural vanilla extract. In the United States and Europe, vanilla is the only spice protected from substitutes because it has a Standard of Identity. Both natural vanilla extract and artificial vanillin are part of the FDA’s Generally Recognized As Safe (GRAS) list of ingredients that can be added to food. Thank you for a great question.

The fruits must be fermented and dried for the flavor to develop. Vanilla beans are sold whole in some stores. Take 1/2 pint of cheap vodka. Pour out 1 oz. and dispose. Add 2 chopped vanilla beans. Recap and store in a dark place for 2-3 months. Shake occasionally. Filter as desired. Use just like commercial brands. (NOTE: DO NOT UNDER ANY CIRCUMSTANCES USE LABORATORY GRADE ETHANOL FOR MAKING ANYTHING TO BE CONSUMED. IT HAS AVIATOR FUEL ADDED TO PREVENT ITS USE AS A BEVERAGE.)
