I bought these for my son to take to work for lunch. Apparently his co-workers found the smell so offensive they asked him not to eat it at work again. Maybe it was a bad batch...

Raw Cacao Powder differs greatly in taste than processed Cacao Powder. Commercial cacao powder is often triple fermented and then roasted. Commercial companies are more interested in a product which has no nutritional value but great consistency in flavor. Commercial Cacao Powder is mono tonal in flavor. Raw Cacao is everything that Commercial Cacao isn't. It is a antioxidant super-food which has no equal. The taste does vary slightly from one part of the year to the next. As to taste, it has a wonderful intoxicating tannin like aroma with mild overtones of Mahogany. In foods it has a complexity which some cooks will absolutely love while the others who read from the book may want to go back to there standard one dimensional cacao. In baking, I believe it goes well with other flavors such as Almond Extract. If you want to do an extraordinary butter cream icing with a tad of Almond extract, your icing will have no equal. In chocolate cake I personally would go heavy and do a buttermilk or sour cream cake. The acid helps to unify and amplify flavors. I like making cake with 60% cake flour which is about has about 5% wheat gluten and 40% rice flour. The reason for this should be obvious. The heavy texture that rice flour imparts makes your cake stand proud and one bite is then never more than enough.  Raw Cocoa powder is rich in polyphenols, such as catechins and procyanidins, and has been shown to inhibit low-density lipoprotein (LDL) oxidation and atherogenesis in a variety of models. Human studies have also shown daily intake of cocoa increases plasma high-density lipoprotein (HDL) and decreases LDL levels although the drug companies having endeavored to understand the mechanism in which this happens.

The Switch bills itself as "great tasting healthy alternative to soda" so I decided to see for myself. The first thing I wanted to do was compare it's nutritional facts against my favorite orange soda and this is how they matched up:  The Switch Orange Tangerine (Per Serving) 16.97 Calories 1.8 mg Sodium 4.3 g Carb 4.1 g Sugar 20% RDA Vitamin A 100% RDA Vitamin C  National Brand Orange Soda (Per Serving) 15.8 Calories 3.7 mg Sodium 4.3 g Carb 4.3 g Sugar  Besides slightly less sodium, the addition of vitamins and no added sugars <a href="http://www.amazon.com/gp/product/B001LG945O">The Switch Orange Tangerine, 8.3 Ounce Cans (Pack of 24)</a> didn't really stand out as a winner based on nutritional facts alone. So when it came to drinking it, I had expected to prefer the more natural taste that The Switch might offer.  Unfortunately the main two juices used in this drink are Apple and Grape and that left me not tasting the "Orange Tangerine" as much as I had wanted.  Overall when comparing the two beverages not only did it not impress me with taste or nutrition, but add on the obvious price difference ($.03 per ounce vs. $.11 per ounce) and The Switch won't be causing me to switch. I'm happy to stick with my good old orange soda.
