A homemade hot sauce recipe made with garden grown aji peppers that have been fermented for 6 weeks, then processed with fresh garlic, lime juice and vinegar. Simple and delicious.

Fermented Aji-Garlic Hot Sauce Recipe
My fermentation experimentation continues. I grew several aji pepper varieties this year in the garden and you know, if you've ever grown aji peppers, that they are VERY productive.
It's one of the reasons I typically grow at least one aji variety each year, because of the large yield.
You'll find a good range of them as well, from sweets to hots, with flavor differences in between, so you're free to grow to your own taste preferences. The thing is, since they are SO productive, what can you do with all of those peppers?
You can cook them into meals, of course, freeze them, dry them to make homemade chili flakes and powders, but don't forget one important way to keep them...
HOMEMADE HOT SAUCE!
YES!

Fermented Aji-Garlic Hot Sauce Ingredients
- Aji Peppers. Fermented – I used Aji Habanero peppers (Learn How to Ferment Chili Peppers Here).
- Fresh Garlic Cloves. Chopped.
- Lime Juice.
- White Wine Vinegar.
How to Make This Fermented Aji-Garlic Hot Sauce - The Recipe Method
I took a solid pound of ajis - Aji Habaneros, in this case - and fermented them for 6 weeks. Learn How to Ferment Chili Peppers Here.
I used the brine method, which is my preferred fermenting method with chili peppers. Basically, I processed the peppers, added them to a jar, and poured a salt solution over them to cover. Leave a good inch of head space.
The brine is made by mixing 3 tablespoons of sea salt with 1 quart of unchlorinated water, which creates the ideal environment for good bacteria to do its work.
The process of fermentation basically breaks down the peppers, mellowing them out a bit, developing flavor. You can typically see that activity in the form of bubbles in the brine, though sometimes you'll have a quiet fermentation and won't see the bubbles.
As the process slows, activity tends to stop after a week or 2, though you can continue fermenting. In this case, I left mine in the pantry for 6 weeks before moving onward.
This is a very simple recipe once your fermentation is completed. I was looking for a no-nonsense hot sauce to keep in the fridge for splashing over foods, something vinegary, something garlicky, something a bit spicy.
This is a great one for that. Just cook the fermented peppers, including the brine, with lime juice, fresh garlic and vinegar, then process it in a food processor.
I strain mine afterward to give it a consistency more like Tabasco sauce, though you can keep it more chunky and solid if you'd like. If you DO strain it, try dehydrating those solids for a bit of homemade seasoning powder. There is plenty of life left in that pulp!

Let me know how it turns out for you! Happy hot sauce making!

About the Fermenting Process
Most of the work is in the fermenting process, and that isn't much work. It's mostly chopping, measuring, and WAITING. Waiting is the hardest part.
You can ferment for a week or 2 to let the good bacteria do their work, but you can easily go longer. I often go about 8 weeks for mine.
If you're new to fermenting, I have some information you can refer to. See: How to Ferment Chili Peppers (How to Make Fermented Pepper Mash).
A few notes on making hot sauce.
Can You Make This Hot Sauce with Fresh Instead of Fermented Peppers?
Absolutely. Just skip the fermenting steps. You will still get a hot sauce with great flavor.
Fermented peppers offer up a milder flavor for your hot sauce blends, so the resulting hot sauce is typically more complex and nuanced than many other hot sauces. The choice is yours.
Adjusting the Hot Sauce Heat Factor
These aji peppers have a good level of heat to them, but if you're looking for an even HOTTER hot sauce, either add in a few heat level peppers that you'd like to cook with, such as habanero peppers or ghost peppers, or just use those exclusively for a different but delicious sauce.
Recipe Tips & Notes
- If you like the bottles that I am using, I find them locally sometimes, but I also order them through Amazon. Here is a link to some bottles I like (affiliate link, my friends!): Swing Top Glass Bottles, 8.5 Ounce - Set of 4. If you like the smaller bottles that most hot sauce makers use, here's another link: Hot Sauce Bottles, 5 Oz - 24 Pack.
- For longer storage you can process this hot sauce. Just be sure to use proper canning/jarring safety procedures.
- Aside from drizzling this sauce over anything you please, here's a post I did about How to Cook with Hot Sauce. As if you need even MORE reasons to eat hot sauce. I hope you find it helpful!
Storage & Leftovers
It should keep a few months easily in the fridge, or even longer. It's all about the acidity.
To be technical, target level ph for shelf stable foods is below 4.6 ph, but should probably be lower for home cooks, around 4.0 or so, to account for errors. If you're concerned, add more vinegar to lower the ph. Sauces made with fermented chili peppers will last even longer.

Gave this one a try Mike. I started off with a basic mash but it didn't develop enough brine to cover the peppers so I added a bit of brine pepper mash salt+water solution until the peppers were covered.
After about 6 weeks I cooked the peppers, garlic, white wine vinegar and juice of one lime per the recipe.
I chose to blend it all in a blender for a thicker sauce. And boy is it thick. I ended up adding about another 1/3 cup of white wine vinegar and the juice of another lime to try to thin it out some more but it's still kind of thick. Might be difficult to pour out of a bottle thick. Should I just keep adding more vinegar and lime juice until it's thin enough to pour at least?
Is there a more recommended way to thin. Some other kind of liquid perhaps?
Mike Hultquist says
Hey, Brian. Yes, you can add more vinegar to thin, but you can also use citrus. You CAN thin with water if you'd like, but check the acidity if needed for longer keeping. 4.6 is considered shelf stable. I always shoot for a bit lower. Let me know if this helps.
Brian says
Thanks for the response and input Mike.
I actually used a mild simple-syrup (sugar and water, but much less sugar than the typical 50%) to thin it down. It worked well and also added a nice tiny bit of sweetness.
I do need to get a ph meter though.
The heat level is nice from those lemon-drop peppers. Hotter than most commercially produced hot sauces (without getting into the niche super-hot ones). Hotter than I think most people that like "commercial" hot sauces can handle, but at a good heat level for hot sauce aficionados.
Mike Hultquist says
Excellent! Glad to hear it!
Chris Brown says
Hi Mike,
Is it ok to mix fermented chili peppers with fresh chili peppers to make one batch of hot sauce? Not sure if I should make separate batch with fresh pepper and another separate batch with fermented peppers or OK to mix them together to make one happy batch. Thanks so much.
Mike Hultquist says
Hi, Chris. Absolutely, you can mix them together to make a sauce. No problem at all. I hope you enjoy it!

Mike-
This recipe may have just solved a mystery. My wife's favorite recipe for hot sauce here in Costa Rica (made here) is "Iguana Salsa - Picante Habenero" ...it's a step above their Jalapeno hot sauce. I have never been able to reproduce this (until now.)
Here in Costa Rica peppers called habaneros (on the plant) are most often Aji Habaneros. Which is what you prefer for your salsa in this recipe.
I think Iguana stole your recipe (lol.)
This recipe is equal ...or better than the Costa Rican Iguana Salsa Picante Habenero Sauce.
I did add a little salt which made it a little better ...and a little palm sugar (maybe not the best move ...honey posssibly a better choice.) But still 5 stars and thanks!
BobB
Mike Hultquist says
Glad you enjoyed it, Bob! Great to hear!
BobB says
We really do enjoy it. And we puree it as much as possible ...but do not strain/filter it. As such, nice recipe!
My lips have a tasty and comfortable burn at this moment from this sauce.
Thanks again!

Abbey says
We made this sauce with Carolina reapers and scorpions. It's great!!! Love the fermented hot sauce recipes!
Side note, I had questions about the fermentation process so emailed Mike. He was quick to reply with great answers!!!
Mike Hultquist says
Thanks so much, Abbey! Glad you're enjoying them!
Ward A Moroz says
I buy swing-top 8.5 oz glass bottles from Dollarama for $1.50 CAD. I imagine there are American equivalents to Canadian Dollaramas.
Mike Hultquist says
Perfect for hot sauces! Yep, we have "The Dollar Store" and a few others.
David Howell says
I made this today. Great recipe. I used honey fermented garlic instead of fresh and added 1/2 a reaper at the blend for a little extra heat. I’ll definitely be trying more of your recipes. Thanks!
Mike H. says
Sounds like a plan. Thank you, David!
Brian says
Your website and content is amazing! Will be purchasing your books soon. I am in the process of making this with Aji Limon peppers. Only some of them are yellow however. I'm sure it will not be as good as if they were all fully ripe. Do you think it will still turn out usable?
Mike Hultquist says
Thanks, Brian! Yes, I think the sauce will still be good. It just might have a bit of the "green" or verde flavor, but still great for recipes. Let me know how it turns out for you. Enjoy!
Jesus Franco says
For how Long it will be good if you use fresh garlic and fresh lime and it need ti be on a deidge or not? Thank you
Mike Hultquist says
Jesus, because of the vinegar content, this should last 6 months out and 12 months in the refrigerator. If you have concerns, you can add more vinegar and measure the pH. Shoot for 3.5 or lower for home keeping. Best to refrigerate.
Jesus Franco says
Sorry and I need to know if i need to put the hot sauce on the fridge
Thank you
Mike Hultquist says
Jesus, no, it does not need refrigeration, but will last longer in the fridge. I have a post on that here: https://www.chilipeppermadness.com/frequently-asked-questions/refrigerating-hot-sauce/. This does NOT need
forest says
I just made this with 50 aji pineapple peppers and it's great! Think i messed up though I only added a splash of the brine with the vinegar do you mix the whole quart of brine with it? or just 1/3 cup of vinegar
Mike Hultquist says
Forest, you did it right. There are different ways to do this recipe. You can use all of the brine and have a very thin sauce, or dump the brine and use fresh vinegar for the flavor. Since the peppers are fermented, you can technically just process the whole thing and skip the cooking. It's already preserved and low in acidity. I sometimes prefer to dump the salty brine and use vinegar, like for this recipe. Cooking removes the probiotic benefits, but stops fermenting altogether, and preserves the flavor as it is. Anyway, using a bit of the brine is great for extra saltiness and thinning the sauce. Let me know if you have any other questions.
Peter George Hauschner says
The last two batches I fermented I used part brine, lime juice & vinegar to keep that delicious fermented taste and the probiotics, rather than cooking it. But I also added Espolon Tequila Reposado to really slow or stop the fermentation and still keep the probiotics. I think it worked, but I still keep in in the fridge. Great taste and has that fermented flavor. No bottles have exploded yet!
Mike Hultquist says
Sounds great, Peter! Glad you enjoying it!!
Alexander says
As always, a great recipe! I wonder if it would make sense to ferment the chili and the garlic together and just add the lime/vinegar later. But I am always a bit cautious when it comes to fermenting garlic.
Mike Hultquist says
You can definitely do that, Alexander. It mellows the garlic. Enjoy!
