Miracle berries contain only a small amount of natural sugars and produce a mildly sweet tangy taste just a tiny tingle of tartness is detectable. One of the unusual characteristics of this berry is that it causes a difference in our taste perceptions after we eat it.
Acidic well drained soils rich in humus and organic matter are preferable. Full sunlight is required, even partial shade is intolerable.
Sour foods such as lemons and limes will taste sweet. This is caused by a carbohydrate found in the berry known as miraculin which adheres to your taste buds and creates the effect. It blocks the receptors which detect the sourness of some foods and in turn the receptors that detect sweetness are activated. The effect will generally last about 1/2 hour
In the USA, an attempt was made to market the fruit, but the USDA jinxed the project by labeling it as a food additive instead of produce, which it actually is. Conspiracy theorists claim the project was sabatoged by the Sugar and artificial sweetener Industries. In Europe, the EU lists it as 'Novel Food', and it requires a safety assessment before it can be marketed.
