Preserving peppers in oil

Hi all, help

Over the last year or two, since we got an allotment, I've really picked up preserving things. The only thing I cant seem to get the hang of, however is peppers in oil. I roast them, put them in the bag to cool, peel them and whack them straight into sterilised jars, and fill them with good hot olive oil (we get it direct from the grower in the Kalamata region - he's the father of a friend of ours, and we get the stuff the family use for themselves).

The problem is that they go slimy and look as though they are going off - they get a sort of mucus around them. It doesn't seem to affect their taste, but I wouldn't serve them straight out of the jar, I cook them in something. Any ideas why they're slimy? (I'm using them within a month or so)

Cheers

Re: Preserving peppers in oil

Check this out http://www.foodscience.csiro.au/oilvine-text.htm it's about botulism growth in preserved veg.

The slimy stuff is probably not botulism (but probably contains it, hopefully at low enough levels to prevent illness). It's probably just the peppers dissolving slightly in the oil. Refrigeration would help.

Why do you use hot olive oil? It's not going to be any more sterile and you could be destroying the good parts of the oil. I suggest adding a good slug of vinegar and then the cold/room temperature oil. That should take care of any nasties.

Re: Preserving peppers in oil

Yikes! I did keep them in the fridge once opened, but not before - I noticed the slimy bits in the closed jar.
Thank you... BTW, I heated the oil because the recipe I used told me to - seemed strange, as I thought the exclusion of oxygen was the point of the oil but also it never mentioned anything about vinegar / acetic acid.
I will have another go with vinegar as well.
Cheers

Re: Preserving peppers in oil

whenever i do roasted peppers i end up just freezing them in portioned zip bags.. they thaw perfectly and then you can pull out 1 bag at a time to  put them in a jar and add some good oil to keep in fridge . when your close to done that jar pull another zip bag out of the freezer and your laughing... i will also tend to add any extra veggies i have grilled to the jar .. grilled  asparagus or mushrooms or eggplant  marinated in with the peppers for a day or two  is wicked on any sandwich.  yummy  yummy   mm this is making me soo hungry now.

Re: Preserving peppers in oil

exclusion of oxygen will slow oxidation of the food and improve shelf life. However only acid can kill some bacteria.

Let us know how it goes and if you come up with a good method

Re: Preserving peppers in oil

I'm just in the process of making this now.  I'm taking a recipe from River Cottage Preserves book (p198).  It is originally for Asparagus preserved in oil but suggests substituting with char-grilled peppers.

It brings 200ml of water and 300 ml of cider or white wine vinegar to the boil, then it's removed from the heat and covered to keep warm.  The char grilled veg are dipped into the hot vinegar bath and left for 3-4 minutes.  "This sharpens the flavour of te asparagus (or in this case pepper), while the acidity assists in preventing bacterial growth."

Remove from the vinegar bath, pack it into the jar with herbs, etc.  Add 70ml lemon juice to the jar (again for acidity to fight bacteria) and then add olive oil (unheated).  Store in cool, dark place, leave 6 weeks to mature.  Consume within 4 months.  Store in fridge once opened.

I'm going to try Ashen's freezer portion idea too, and see which works the best.

Re: Preserving peppers in oil

Sounds good, I like the use of the acid bath and the lemon juice.

Re: Preserving peppers in oil

This may seem a bit odd, but....I think the idea of freezing peppers, whether they be raw or roasted is great. But when you take them out and want to put them into a jar of oil, perhaps for a few weeks before use, could you use cheaper vegetable oil, rather than olive oil? If you added some fresh herbs such as rosemary, thyme, mint, would the taste be as good? and perhaps less calories?

Re: Preserving peppers in oil

if you have roasted them before freezing you will notice a fairly large amount of natural pepper oil with the peppers when you thaw them .    I don't think adding olive oil is really called for; maybe just a bit of neutral oil if you really want it.

Btw pretty much all oils have the same caloric values
