I have seen a restaurant that has chili pepper in the olive oil bottle, it gave the oil a delicious chilli taste. I am planning to do the same at home.

I wonder how to choose the chilli I will be using. What difference do the different types (jalapeno, red chilli, etc.) have on the finished product? I am aware of the safety issues as discussed in this post, they are not part of the question.

  • Sorry, but we don't answer duplicate questions. The other question already explains that the practice is not safe, and repeating the same thing doesn't help you or us. Since you asked two different things, I edited the duplicate part out. We also don't answer "best" questions, so I changed it to ask how to choose the chilli.

You can use any type of chili depending on how spicy you want the oil to be. You could use ghost peppers to burn the insides of your mouth, or perhaps use Jalapeno for a more milder heat.

You can use the Scolville Scale to decide which pepper to use. At the end of the day it comes down to your personal preference.


I used to make my own chilli oil (for cooking with) from home grown chillies. Made with fresh chillies it can go mouldy within a few days even in the fridge (though sometimes it lasts longer) so the first factor is use thoroughly dried chillies.

I grow my own, and used to mainly grow Apache. This is a moderately hot, thin-fleshed variety, and it's ideal - the thin flesh dries well while the heat is sufficient for most things without too much risk of being overpowering. Drying is best done outside because the capsaicin fumes are a bit much indoors. I use a dehydrator on a sunny day.

I do encourage you to read up on the botulism risk. My personal assessment after some reading of the scientific literature was that combining pH adjustment, refrigeration, and only using the oil when it's getting cooked, the risks are negligible. Guidance in some countries says otherwise, and that's reasonable because no step in the process is foolproof. I have given up not so much because of the risk, as because I don't have much fridge space. Now I make chilli flakes instead, and add them to the oil at the start of cooking. The effect is very similar. If you want preserved chillies for pizza, pickling then works very nicely.
