Experiment: Making Chili Oil w/ Fresh (i.e. Non-Dried) Chilis

Not sure if anyone else is especially interested in this topic, but I thought I’d share an experiment I did today. And if it fails to strike a chord with anyone else, that’s fine, it will just be my own log for future iterations!

Earlier this year I had some extra space in my garden, and on walking through the local garden center I randomly bought a couple of plants simply labeled “Calabrian Chili.” Not sure what to expect, nor with much in mind for them.

What I got, after a long wait, were hundreds of these things:

These are, I now know, “sigaretta” peppers and there are in fact a lot of varieties of Calabrian chilis.

In any case, these are thin-walled, very flavorful, fairly hot, and absolutely packed with seeds. I don’t like to eat pepper seeds - I find them at best flavorless, at worst bitter, texturally not at all good, and some varieties like Thai bird chilis, seem to cause me GI distress. I still had no clue what to do with all of these peppers, so as I harvested them going into fall I began to deseed them and freeze the bodies until I came up with some sort of prep. (Aside: This whole thing was a total pain in the ***. In the future I’m going to try to find and grow the “naso di cane” variety instead.)

At some point I had a business trip to DC and ate dinner at a place there called Queens English. Decent food (not amazing), but what did stick with me was the house chili oil, which I was told by the waiter was made with fresh chilis, and flavored only with garlic, salt, sugar, and MSG. This chili oil was like none I’d tasted before: Soft and jammy, not “crispy” at all, very garlicy, a bit sweet, and deeply flavorful. Inspiration struck and I knew what I was going to do with the Calabrian chilis.

I googled, and googled, and googled some more. There aren’t a ton of recipes out there for fresh chili oil. (In English, at least. A Reddit thread I found along the way said that there are many in Chinese, but I couldn’t figure out how to make Google give me those.) What I found basically said to chop up the chilis in a food processor with garlic, then cook them in oil, starting cold, until they stop bubbling – thereby indicating the the surface water is driven off – and then to add seasonings. Ratios of chili to oil and garlic, not to mention suggested seasonings, were all over the place. I also didn’t like the idea of adding dry salt or sugar to an oily mixture after cooking; would it even mix in?

In the end I cobbled together my own recipe by taste, eye, and what I happened to have:

  • 300g de-seeded pepper bodies
  • 100g garlic whole cloves
  • 1.5 tsp MSG
  • 1 tsp kosher salt (Diamond)
  • 2 tsp sugar
  • 1c neutral oil (I used avocado, because it’s what was open in the cabinet)

I combined everything but the oil in my food processor and pulsed until fairly finely chopped – pieces maybe in the 2mm range. I wanted the powdered ingredients to be able to interact with the water ahead of having the oil in the mix, and this seemed to do the trick.

I put this into a saucepan, added the oil, and started cooking, stirring regularly. Most of the recipes said that the bubbling would abate after 20 minutes. That didn’t happen; actually, the bubbling never stopped. Around 50 minutes in, I noticed that I was getting a lot more residue sticking to the bottom of the pan, and that some of it was starting to get uncomfortably dark, and that’s when I stopped cooking.

End result: Around 300mL of product, which looks like this:

It’s oily, but much more about solids than oil. It’s quite thick and mounds easily. I think I probably could have stopped cooking five minutes earlier than I did. The texture is very close to what I wanted but a touch more caramelized than I think would be ideal. And you can see that the bright red color has faded to more of a brown. (The inspiration oil was also edging toward brown, but less so than what I’ve done here.)

Taste, pretty good! I think I could have gone a bit heavier with the garlic; it’s not quite as present as I would like. But that may be due to the slight overcooking. Seasoning is pretty close to my ideal; maybe just barely too salty. Mixing in the seasonings before the oil seemed to work nicely. Some acidity could work well here too, so maybe I’ll try mixing in some vinegar when I’m eating it.

I bet you just a tiny splash of rice vinegar would do the trick. One of my favorite current hot sauces is a Vietnamese kumquat sauce with kumquat, chilies, garlic, fish sauce, cilantro.

I have a glut of hot peppers from a friend in the freezer, so I may join you here in your chili oil adventure :slight_smile:

I was thinking Chinese black vinegar but I will try both!

That sauce sounds really interesting. Do you buy that at a local store or restaurant? I just had to google what a “kumquat” is…I know I’ve heard of them before but not something I ever recall actually seeing IRL. I wonder if some other citrus would be a good sub?

Next up on this end for hot sauce will be something to consume the three large freezer bags of scotch bonnets I’ve also managed to collect over the course of the late summer/early fall. Thinking mango as a base, maybe? That one I’ll have to cook outside the house!

I love the fermented Calabrian chile paste from Trader Joe’s (Bomba sauce) and was surprised that it didn’t have any garlic in it.

I couldn’t find a recipe for something similar, but I did find one for fermented non-Calabrian chiles which looks interesting.

(Not sure about removing the stems and seeds and only using the skins – I find a lot of flavor and heat come from the seeds rather than the flesh.)

The flavor is primarily in the flesh, and the heat is in the ribs that hold the seeds. If you carefully dislodge a seed (so it has no rib material) and taste it straight, you’ll find that its outside is flavorless. Bite it, and at least for me it tastes kind of bitter. Personally I think it ruins sauce, but obviously that’s subjective!

In any case I definitely like heat, so when de-seeding I’m as careful as possible to leave behind the rib material. But I also don’t like to let anything go to waste, and it’s impossible to thoroughly deseed without taking some of that stuff, so when I’m doing a mass de-seeding – especially of home-grown peppers – I collect the seeds and whatever material is sticking to them and drop it all into a jar and just cover with some spirit. (Usually tequila or vodka; but I’m going to use white rum for my scotch bonnets when I deal with them, in keeping with a sort of Jamaican theme.) I leave that for a day or two, then go through a coffee filter, and now I have an interesting somewhat spicy addition for cocktails.

Clever! I bet a few of your whole chillies would make an unusual shrub too!

I like the cold method described by Michael Dietsch.

Rice vinegar will be more neutral, I think, than black vinegar, but the latter might add a nice dimension.

The kumquat sauce is a purchase from a great Vietnamese bakery/food shop in South Philly, and I love it so much I have an extra bottle (the one I took the picture of — the open one only has dredges left in it :smiley:).

We’ll be back later this year, and I plan on picking up a few more bottles — I’d gifted one to a friend who puts it on many Chinese, SE Asian and East Asian dishes she makes, and there are other folks who were clamoring for their own bottle :grinning_face_with_smiling_eyes:

You could probably use orange or blood orange for the citrus kick if you can’t find kumquats, although most supermarkets tend to carry them.

One of my other favorite, restaurant made hot sauces was at a Syrian hole in the wall in Berlin: very citrus-heavy & fresh, with bell pepper, lots of garlic, and a number of spices and seasonings they wouldn’t share. I should go back again next summer and have another taste to try and recreate at home :slight_smile:

Interesting.

I’m working with Scotch Bonnets as well!

Unfortunately right now I have a lot more flowers than peppers,

but I have successfully overwintered Scotch Bonnets before.

Very interesting! Thanks for this post!

Regarding the pepper seeds issue: I’m with you! I consider the seeds a sign of an inferior product, especially if the seeds are mature and hard. Soft seeds in pickled green peppers, like jalapeños, no big deal.

If you want to make a fermented hot sauce, you can coarse chop, at low speed or mash peppers with salt and lacto-ferment the mash. Brine will develop if fresh peppers are used and bacteria will break down cells to release flavor and juice. Once done fermenting and it’s good and acidic, strain out the skins and seeds and you’ve got a basic hot sauce. Kept refrigerated, it’ll last months. Add vinegar if you want it shelf-stable. Might be a good use for the seedy sigarettas. 3% salt, by weight of the peppers, should work.

Another idea is to cut the peppers in half and make oil, seeds and all. Then strain the oil. You won’t get the flakes, but it’s easier. Maybe the flavor would be similar; who knows.

With dried peppers, it’s easy to use a fan to separate the seeds from the pepper flakes. With whole dried, the seeds are easily dislodged by cutting off the stem end and running a thin rod inside to loosen the seeds so they fall out.

The birds have kindly planted several pequin/chiltepin bushes in my yard, and they are ready to be harvested. I think I’ll give the chile oil a try. Of course my peppers are too small to seed. Oh well.

Thanks! I had a delicious drink at a bar recently with a habanero shrub. I’ve never made my own before so this could be a great next project.

That’s a nice tip! I did discover a little trick along the way for making deseeding a bit easier for thin fresh peppers: If you roll them in your fingers a bit – hard enough to hear and feel a “crunching” – that dislodges a lot of the seeds. Then you cut it open and the majority of them fall right out. Doesn’t really save a tremendous amount of time but still less pain than carefully removing them with the tip of a paring knife as I was doing previously.

When I make my chile oil (from dried), I often add some citric acid - about a half tablespoon to 4-6 cups of total product. We like the tang it adds.

This looks a lot like the typical chili oil you might find in a Hong Kong noodle shop. Many of those are made by the owner/chef and may have slightly different recipes or tweaks. These are some of my favorite chili oils, so this is meant to be a compliment. :grinning_face_with_smiling_eyes: I actually prefer them to Sichuan style chili oil or even the LGM, which I find can be salty, or spicy, or sometimes too crunchy (I am don’t care for the peanuts in there), but maybe not as umami forward as the ones in the noodle shops.

Well thank you for the compliment! That is high praise indeed. But you’ve just ruined my afternoon. Now I’m going to be thinking about noodles instead of work. Off to the kitchen to find the closest match; probably a forgotten bag of half-stale chips.

BTW have you tried the Momofuku chili oil? That’s my favorite store-bought one thanks to its high ratio of solids to oil and its various umami ingredients.
