Ultra Vanilla Cupcakes - Vanilla vs. Vanillin

It's been a long and demanding academic year... and now I'm done. I finished all my exams and coursework and will be graduating from he University of Nottingham this July with a MSci Neuroscience degree. I can't believe my student years are most likely officially over...
Despite the long hours spent revising and writing abstracts, grant proposal and dissertation, I found some time, every now and then, to do some cooking and baking. Nevertheless, I didn't post any of my recipes. There has been a demand for them, and I apologise that it's only now that I'm getting to it. Throughout the year, I came up with some very exciting flavours, however I have decided to start with a very traditional one - vanilla. First, this is a recipe that can be build upon and I'm probably going to refer to it fairly often; and second, there can never be enough vanilla - yes, it's my favourite flavour. It works well with light fruity fillings and frostings as well as with intense chocolatey and coffee mixtures.
You might have noticed that all of my recipes containing vanilla extract have a note attached saying that you shouldn't use the clear essence (in CZ and SK, Dr.Oetker is the one commonly found in stores). Also, when buying vanilla-flavoured sugar, you should double-check whether you're buying the real thing, or just the cheaper vanillin-flavoured one. A hint - if it's cheap, it's most likely the artificial vanillin version. A spoonful of vanillin in your cupcake/cake/whatever batter will most likely result in a very artificial, chemical and unpleasant taste. If you don't have the natural vanilla extract or seeds or vanilla-flavoured sugar and are thinking about using the artificial version, please don't. Your batter, for any cupcakes except for the vanilla ones, will be just fine without it. For the ultra vanilla cupcakes, recipe for which you can find below, you really need to use the real thing!

My humble collection
OK, let's get a bit geeky again!
Most of the vanilla-flavoured foods have a picture of a long dark brown bean and sometimes a yellow blossom next to it... That blossom is typical for the orchids of the genus Vanilla, the fruits of which are the oily long dark brown seed pods. Vanilla orchids grow like vine, climbing up trees or other support. For each blossom, if properly pollinated, there is exactly one pod. Even though the "most famous" vanilla nowadays is the one grown at Madagascar island, the so called Bourbon vanilla, the Vanilla genus originally comes from Mexico. Vanilla's journey from Mexico to other countries wasn't easy. The plant can only be naturally pollinated by bees of the Malipona genus, found exclusively in Mexico (mountain bees). Attempts to bring the mountain bees outside its natural territory failed, and only after artificial hand pollination was introduced in 1841 could vanilla pods be grown and harvested around the world (in suitable climates). Vanilla growers have to inspect their orchids at least once every day to be able to hand-pollinate, as the flower only lasts about one day, or even less. It is therefore no surprise that vanilla is considered the second most expensive spice, after saffron.
Despite its costs, vanilla flavour is abundantly used in the food industry. Nevertheless, to make the production of vanilla-flavoured food more affordable, artificial synthetic vanillin obtained by chemical synthesis from the petrochemical guaiacol is mostly used to generate this favourite flavour. Although vanillin (4-hydroxy-3-methoxybenzaldehyde or O8H8O3) is a major contributor to the characteristic aroma of vanilla, its contribution is still less than 50%. There are hundreds of flavour compounds found in the vanilla pod, combination of which results in the specific smell and flavour called vanilla. 
In conclusion, vanilla essence usually comes in two forms. The real seedpod extract containing several hundred different chemicals, including acetaldehyde, acetic acid, furfural hexanoic acid, eugenol, and methyl cinnamate; and the synthetic essence consisting purely of synthetic vanillin in ethanol.
(Don't be fooled by a brown or amber colour of the essence, some manufacturers add colourings to make it look like the real thing!)

Ultra Vanilla Cupcakes with Frosting Inspired by my Great-grandmother
Just a few notes to this recipe...
The frosting recipe
was inspired by my great-grandmother's egg-yolk vanilla cream which she used as a filling for various pastries, my favourite being mini žloutkové věnečky (mini egg-yolk chaplets).

I used my home-made vanilla sugar (both granulated and powdered). It's very easy to make your own - just take a jar and fill (3/4) with sugar then take vanilla pods split in two (I usually recycle, so that I use the seeds for baking/cooking and than take the "empty" pods) and stick them in the jar so that they are all covered in sugar. Shake the jar a few times and leave it closed for several days. Tadaaa - after a few days you can open the jar a enjoy the rich vanilla smell - just like that you made your own vanilla sugar.

The Unofficial Schwazwälder Cupcakes

Long time no see... ! I'm enjoying my (probably) last long summer holiday, and although I still find time for cooking and baking, I moved, left my kitchen behind and had to start adjusting to a new one. Fun. As I'm moving long-distance, I got to do some shopping - new trays, cupcake cases, mixer, measuring cups... and I also got to know my new neighbour who seems to be interested in tasting my culinary experiments, and,  in exchange, offered to supply me with his home-grown tomatoes.

Since my mum and grandma love to make cherry jam and the pantry at my parents' house is slowly filling up with dark red jamjars, I got inspired... I've decided to bake some Black forest (Schwarzwälder) cupcakes for my high school reunion and for Honza's gaming session.
Little did I know that my cupcakes cannot be officially called "Black forest"... The original Black forest cake has to contain cherry brandy, at least that's what the German Leitsätze für Feine Backwaren (Guidelines for Fine Bakery Products) say. According to these "guidelines", the cherry brandy flavour has to be "clearly distinguishable" if the "fine bakery product" is to be called schwarzwälder. 
My cupcakes don't contain any cherry brandy or cherry brandy flavourings... Be aware that the bellow described recipe cannot therefore be officially considered "black forestish". Nonetheless, despite my ignorance of German traditions and guidelines, the cupcakes met with positive critique.

CNS Stimulating Mocha Cupcakes

Ivka, one of my lab friends, celebrated her birthday yesterday. She, as well as the rest of the serious scientists, cannot imagine a day without coffee. It is understandable, considering the hours spent in dark rooms, sterile environment without windows, and late afternoon and evening shifts... From all the different flavours of cupcakes, Ivka likes the mocha ones with espresso mascarpone frosting the most, and it was therefore the obvious choice for our little "lab-rat" celebration... 
C2H10N4O2, or caffeine, is a xanthine alkaloid compound found in the leaves and beans of coffee plant. It acts as a CNS stimulant in humans and, as such, it has the power to temporarily ward off drowsiness and restore alertness. Caffeine has several other names which are often mentioned when talking about its different sources. These include guaranine, mateine, or theine found in guarana berries, verba mate, and tea, respectively. From the evolutionary perspective, caffeine, commonly found in over 60 plant species worldwide, is believed to have a protective role, as it acts as a natural pesticide which paralyses and kills various insects.
Apart from caffeine, coffee also contains trigonelline, a bitter alkaloid which has a significant role in the development of flavours and aromas during roasting. During the roasting process, trigonelline decomposes and gives rise to a large class of aromatic compounds (pyridines). These are responsible for producing the sweet/caramel/earthy-like aromas.
The coffee aroma is perceived by two different mechanisms. We can sense the scent nasally via smelling the coffee through the nose, or retronasally, when we swallow the coffee or when it is present in our mouth and the volatile aromatic compounds drift upward into the nasal passage.

Vernal Equinox Celebration - Blueberry Cupcakes

I'm not a big fan of Easter. Not only because I consider myself an atheist, but also because I resent the Czech traditions related to this holiday... The custom of often drunk men spanking women with willow rods and throwing cold water on them, and women rewarding them with decorated eggs doesn't really appeal to me... On the other hand, who wouldn't like a day off from work? So I decided to celebrate the end of winter, vernal equinox.
...and, about a week ago, I made these blueberry cupcakes with lemon mascarpone frosting, decorated them with chocolate candy eggs... and enjoyed a free Friday and Monday in Prague with Honza, visiting our grandmas and aunties.
By the way, blueberries are good for you. Apart from a lot of other phenols, they contain a chemical called chlorogenic acid, an esther of caffeic acid and L-quinic acid. It is a powerful antioxidant and, in spite of its name, it doesn't contain any chlorine. Its name comes from the Greek xλωρός (light green) and -ϒένος (a suffix which means "giving rise to") - when the chloronergic acid oxidizes, a green colour is produced. 
Blueberry-enriched diet was shown to provide cellular protection against oxidative stress and reduce a kainate-induced learning impairment in rats (Duffy et al., 2008). Antioxidant properties of natural polyphenols are also investigated for their therapeutic potential for Alzheimer's disease (Choi et al. 2012), as the fruit polyphenols have been shown to have beneficial effects on brain aging (Lau et al., 2005).
