US-based food YouTuber: "Now we let the dough rise for 30 minutes…" – Me, surprised: "Huh? Why is he suddenly using metric units, and not bunny heartbeats or fractional moon cycles or something?"

Creating a design like this usually involves creating *a lot* of variations – thanks to everyone who participated in the polls and helped me find the best ones!

Here are some "dead ends" I didn't end up picking! :D

Here are two more resources I found while preparing my ingredients today: Jan Krüger's blog post about tweaking cola recipes jan-krueger.net/making-cola and Richard Grove's "Notes on Making Cola", which go deeper into food chemistry! sparror.cubecinema.com/cube/co

Open Soda opensoda.org/?cat=6 has two pretty weird ones (including a bubble gum soda?!), but that's pretty much all I found. There still seems to be potential for reverse engineering! :)

I made DIY cola like this once before. What I'd be really excited to try is making other flavors: Orange soda! Cherry soda! Almond & apricot soda! <3 The problems is that I don't know of many DIY recipes for sodas except cola, which is surprising!

I might tweak the oil ratios to accentuate the citrus flavors a bit more in the next batch. Also, I thought this would be too much food coloring, but it seems pretty perfect!

I like my drinks *really* sour, so I might add another... 10 g of citric acid to this batch. There is a slightly bitter aftertaste, which I attribute to the artificial sweetener I'm using.

Show thread

It's good! It's really good! The sweetness is just right for me, and the oil blend tastes nice and cola-y! :)

Because this is still a very concentrated solution and hard to handle, I'm diluting it down to 1 L. In theory, this should give a nice cola when diluted further in a ratio of 1:8. First taste test upcoming!

Other recipes would now integrate this into sugar syrup made from 1 kg of sugar, but I want to try a variation using artificial sweeteners. This is a combination of sodium cyclamate and saccharin, which is pretty common in Europe. I'll use 70 ml.

Stop mixing when it starts smiling at you! :D This is our finished cola concentrate. It smells delicious!

As well as 5 g citric acid, and an additional 10 ml of water. You can also add caffeine at this point, but one of the main motivations for me to make my own cola is to have cola without caffeine (it gives me headaches).

Next, we add: 40 ml of caramel color, which will give the cola its dark appearance.

Combine 2 g of gum arabic, 4 ml water, and our oil mixture with a hand mixer. Keep mixing until it emulsifies, it will take on a milky brown color and the oily phase will disappear. This took me about 5 minutes.

Show thread

But oils don't dissolve in water, right? They would just float on the surface!

So what we'll add next is gum arabic, a natural emulsifier, that will help the oil form tiny, tiny droplets that stay dispersed in water!
