If you’re like me and enjoy hot sauce, you’ll love this recipe for homemade Chili Sauce / Hot Sauce (Tuong Ot). Warning: this Chili Sauce is next-level hot because it’s made with Ghost Peppers (also called Bhut Jolokia). These chili peppers are insanely spicy and delicious if you can take the heat. (See below for other chili pepper substitutes.) My Chili Sauce recipe does not have a lot of vinegar like some hot sauces. It’s just a tad tart with a hint of sweetness. Made with all fresh ingredients, the Chili Sauce has a beautiful all-natural red color, smooth consistency and hearty thickness.

Notes on the Chili Sauce / Hot Sauce (Tuong Ot) Recipe, Tips and Tricks
I am using homegrown Ghost Peppers and they are extremely spicy. If you’d prefer something less spicy, substitute with habanero, Thai chili, serrano, jalapeno or any chili pepper you like.
When cutting the peppers, use food prep gloves to avoid touching the peppers directly as they may burn your skin. Also be really careful not to touch your face, especially your eyes or your nose when handling the cut peppers.
Did you know a pepper’s spiciness is concentrated in the seeds? Remove the seeds to make the Chili Sauce less spicy but don’t throw out all the seeds. Reserve some and add to the peppers during the cooking process if it’s not spicy enough.
I use red bell peppers to bulk up the sauce as Ghost Peppers alone would probably be so spicy it would be inedible. Optionally, use tomatoes or even a combination of red bell peppers and tomatoes. I used a ratio of 8 ounces non-spicy peppers to 1 ounce chili peppers.
During the pureeing process, add more water if you’d like the sauce less thick. Also at this time, season to taste by adding more salt, sugar or vinegar if needed.
I like to pass the Chili Sauce through a fine mesh strainer for a smooth consistency, similar to Sriracha. If you prefer a chunkier sauce, you can skip this step.

Yikes, ghost peppers are scary! I’ve been eating spicy food for a few years now (my mom can not handle anything spicy, she think Mild Old ElPaso taco seasoning is spicy) but I don’t think I could handle the heat!
Love your site so much! I really enjoy reading your posts and recipes, I love Vietnamese food. It’s my favourite type of cuisine! Unfortunately, because I live in Northern Ontario (about 4 hours from Toronto) there are no Vietnamese restaurants here. So if I want Vietnamese food I have to cook it, which of course is fun and awesome, it’s not as good as the real thing! So thank you for your blog, I appreciate the amazing recipes you share!
