What Is Senku Cola?
Introduced in Dr. Stone Chapter 40, titled Z=40: Two Million Years in the Making, Senku Cola is not the actual product that Senku decided to make.
While inventing carbonated water, Senku thought of making the popular bubbly drink called cola at Gen’s request.
He, indeed, simplified the recipe because of the limited availability of ingredients.
However, it is interesting to note that Dr. Stone that has been known to explain the science behind its inventions did not go in-depth with Senku Cola.
The chapter did reveal the ingredients and gave a quick overview of how one can make Senku Cola.
So, let’s dive into the ingredients and recipe of this homemade carbonated drink.

Dr. Stone’s Senku Cola Recipe
Now, it is time to hit the lab or kitchen to get on with the making of Senku Cola.
However, please exercise extreme caution while handling any equipment that might be dangerous.
1. Get lime zest
Use a grater or a zester to prepare lime zest. While grating, ensure that you grate only the yellow part of the peel and avoid getting the white pith.
The white pith of the lemon is bitter and is likely to spoil the taste of the end product.
2. Crush cilantro
In a mortar, crush the cilantro leaves. The main aim is to nicely crush the leaves and extract their flavor and aroma.
Squeeze the lemon and add its juice to the crushed cilantro. Then, add the grated zest of the lemon to the mixture.
Start crushing and mixing the above ingredients into a smooth paste. Senku’s idea is to give the cola a homemade feel, and this paste is key for the same.
Strain the cilantro and lime mixture through a fine strainer. This exercise will help in avoiding the lemon zest and cilantro leaves getting into the final product.
3. Get caramel from the honey
The next step involves heating the pan and pouring 4-5 tablespoons of honey. Bring the honey to a boil and reduce the heat to avoid burning it.
Keep stirring the honey until it caramelizes into this beautiful dark brown and rich-looking gooey liquid.
Honey’s caramel is one of the most important ingredients in Senku Cola as it will give the drink its signature cola color
4. Prepare the cola syrup
Next up is making the quintessential cola syrup and for that, we need to mix the caramelized honey and the cilantro-lemon mixture.
It is important that you pour the caramelized honey while it is piping hot. Also, as soon as the caramel is added to the cilantro-lemon mixture, start stirring or the honey will start forming lumps in the syrup.
5. Bottle the Senku Cola
The final step of this recipe involves adding 4-5 tablespoons of cola syrup into an empty small-sized cola bottle.
Interestingly, the exact ratio of syrup to carbonated water is not revealed in Dr. Stone. So, we will have to experiment with our ratio to get that great cola taste.
After adding the cola syrup, pour around 250 milliliters of carbonated water and you have your bottle of Senku Cola.
Extra fun tip: You can spice up your Senku Cola by adding a pinch of chat masala or rock salt.
