Colour is so important in food. A colour can make or break a food (or drink for that matter). But it also gives you a cue as to what flavours to expect. Research has shown repeatedly that the colour of your drink for instance will greatly influence how well you’re able to perceive its actual flavour.
So no wonder foods like red velvet cakes & cookies exist. These bright red foods likely attracts us immensely, especially since it’s generally paired with a pure white topping. A good contrast.
If you’ve never made a red velvet cookie though you might not realize that the flavour of red velvet is actually very much chocolate! I for sure (I know it’s only an n=1) had eaten various red velvet foods, without realizing that they’re chocolate flavoured. That red had definitely impacted my perception! But why on earth did we decide to make red velvet chocolate foods?
Where does red velvet come from?
Bright red colourings are still quite a recent invention. Before the advent of artificial red colourings, most red colours weren’t that bright red. Instead, most natural colours, such as those from beets or red cabbage or somewhat more toned down. Only midway into the 20th century did (artificial) food colouring become more common. These were also the days of the advent of the red velvet, which started in the US.
In the 30s and 40s, colour manufacturers in the US tried to come up with ways to sell more of their food colourings. A common marketing method at the time was to share recipes and organize baking contests. It seems that red velvet started rising through the ranks because of it. Red velvet cakes started winning competitions and it became more of a staple. Nevertheless, it’s real huge rise to fame only came at the end of the 20th century. Nowadays this has resulted red velvet variations of just about anything (including Oreos!).
We’ll likely never know for sure why this red cake was actually a chocolate flavoured one. It might have just been a cake the flavour company enjoyed or it might have had a slightly reddish glow of itself because of the cocoa. Fact is, this bright red cake is a chocolate cake.
Cocoa & red colours
Some people state that back in the day the cocoa powders you could use would actually turn a slight red by adding an acidic ingredient to them. It would have been the same as the reaction of red cabbage colour to acid. Nowadays, they don’t do so anymore (we tested it, cocoa powder + vinegar has the same colour as cocoa powder + water).
Whether it did so in the past, it’s hard to find proof of it. Fact is that cocoa processing has evolved in the past decades. Fact is also that cocoa beans do contain some of those coloured molecules that can be brought out to a certain extent. Whether it’s as bright red as the current day red velvet, I have my doubts.
What about the velvet?
So where does the velvet come from? Velvet cakes were actually in existence well before the red velvet itself entered the scene. These cakes had a finer, lighter texture than others thanks to the use of low protein flours such as almond or corn flours (current cake flours are also low in protein).
What is red velvet?
Red velvet is quite a broad term but the most common theme is that red velvet products contain some sort of slight acidity (e.g. by adding buttermilk or vinegar), a hint of cocoa (but not too much) and often cream cheese frosting of some sort (which can be overly sweet). That said though, even more important is that bright red colour, preferably with some white.
