Let's throwback to my first episode on fermenting and talk a little bit more about the basics. What are those bacteria doing? How safe is fermentation? Let's talk pickling versus fermenting, veggies versus fruits, and cold storage.

Welcome back, my gardening friends, to another Focal Point
00:00:02
Friday episode. Let's spend just a few minutes
00:00:05
together reviewing A snippet of information from a previous
00:00:08
episode, highlighting a new topic, or quickly focusing on a
00:00:11
current event in the Food and Agriculture world.
00:00:14
Let's get down and dirty. When it comes to food safety,
00:00:20
fermented vegetables can actually be safer than raw
00:00:23
vegetables because that very process of fermentation.
00:00:27
Actually kills the harmful bacteria in the foods by using
00:00:31
the bacteria that's in the foods.
00:00:34
So obviously, having said that, you need to keep basic food
00:00:37
safety practices still need to be followed while you're
00:00:39
fermenting foods. And also keep in mind that the
00:00:42
bigger concern is contamination after the veggies have been
00:00:45
fermented. So just make sure when you're
00:00:46
handling your jars and everything you have clean hands
00:00:49
and it doesn't come in contact with raw meat or anything else
00:00:51
like that, right? This is not a fail safe way to
00:00:54
store your food, but. It is a really good way to store
00:00:58
your food to improve the shelf life and also, you know, improve
00:01:01
the health benefits maybe of the food.
00:01:03
Things like cabbage, beets, radishes, turnips, carrots,
00:01:08
those are sort of the beginners fermenting foods because the
00:01:13
bacteria that's living on the surface of those foods already
00:01:17
is doing the fermenting for us. We don't have to add anything to
00:01:22
it in order to get it to start fermenting.
00:01:25
And then once we get into these, you know, easy ones and we sort
00:01:28
of figure out what we're doing with those and we can jump into
00:01:30
recipes that maybe involve inoculating the foods with the
00:01:33
bacteria like, you know, Lactobacillus that can jumpstart
00:01:36
the fermentation process. I say that I'm new to
00:01:39
fermenting, but I actually do make my own homemade yogurt with
00:01:43
milk from our local dairy. And how I do that is by
00:01:47
inoculating that milk with the Lactobacillus cultures from the
00:01:52
previous batch of yogurt. So I'm inoculating it and then
00:01:56
I'm bringing it to a certain temperature and that allows it
00:01:59
to ferment and I end up with yogurt.
00:02:02
Now, I should say there is a little bit of a difference
00:02:05
between pickling, like how we pickle with vinegar versus
00:02:10
fermenting, which could be sort of considered pickling.
00:02:14
You can do Pickles through fermentation, but that doesn't
00:02:18
necessarily mean that you're pickling everything when you're
00:02:22
fermenting. So things can be pickled.
00:02:24
With an acidic vinegar brine, or they can be pickled using a
00:02:30
salty brine Without the vinegar and then it's fermenting during
00:02:35
fermentation. This food is naturally going to
00:02:38
develop a sort of sour flavor because of the chemical
00:02:42
reactions that are going on. So even though both vinegar
00:02:46
Pickles and fermented Pickles may taste vinegary.
00:02:50
One is because of the added acid of the vinegar and the other one
00:02:53
is because of the natural fermentation, so there is a
00:02:55
difference there. So the other thing that I found
00:02:58
when researching this was that it seems that fermented
00:03:02
vegetables will last for a year or more in a good cold storage
00:03:08
location, but fermented fruits should be consumed within just a
00:03:13
few weeks and I guess the reason is.
00:03:16
Fruit has a lot of natural sugars which can add to or speed
00:03:20
up spoilage and also helps it turn into alcohol.
00:03:23
So if that's your intention, that's one thing.
00:03:27
But if it's not, you might have a very alcoholic surprise when
00:03:31
you go to open your fermented fruits.
00:03:32
So a lot of these beginner recipes are definitely focused
00:03:36
towards fermenting vegetables. So here's the thing, people who
00:03:42
ferment foods. Mainly just for their health
00:03:45
benefits. We'll often just store them in
00:03:46
the refrigerator when this process is done.
00:03:49
But if we're looking to use this as a preservation method, that
00:03:53
sort of defeats the purpose, right?
00:03:55
So how should we properly store these fermented foods once
00:03:59
they're ready? Well, in this instance, we go
00:04:01
back to cold storage. So once it's to the point that
00:04:05
you want it to be, then you transfer your ferment to cold
00:04:10
storage. That's between 32 and 50 degrees
00:04:12
Fahrenheit. Remember, a temperature affects
00:04:15
the fermentation process, right? The warmer our home is, the
00:04:18
faster the food is going to ferment.
00:04:20
The same thing goes for the storage once the ferment is
00:04:24
complete. So the cold is going to slow
00:04:27
down the fermentation process, but it's not going to stop it
00:04:30
completely. It is going to continue to
00:04:31
ferment while it's in storage, but it's going to be at a much
00:04:34
slower pace. So we're going to be able to
00:04:36
keep our fermentations for a while in that cold storage.
00:04:40
This is why the colder the location, the better.
00:04:44
Now, what I've read is you can actually lengthen this storage
00:04:48
life a little bit by putting them in cold storage just a
00:04:51
little bit early, right? Since they're going to continue
00:04:54
to ferment slowly while they're sitting there, then you could
00:04:57
keep them from getting too sour or too soft by storing them just
00:05:00
a little bit early. So if you have several jars of
00:05:03
something and you're wanting to use one of them sooner rather
00:05:07
than later, but the other ones you want to keep for the next
00:05:09
six months. Then maybe put three of them
00:05:11
away early and let them to continue to slowly ferment and
00:05:15
let one jar go all the way to where you want it to be before
00:05:17
putting it in the cold sore. Just make sure you're marking it
00:05:19
properly. The one thing that you do really
00:05:21
want to do though is to keep an eye on those brine levels.
00:05:24
You may need to push down those veggies or add a little bit of
00:05:27
brine to keep everything below the brine in order to be able to
00:05:32
avoid mold. So once you put something in
00:05:35
storage, remember we're always keeping an eye out for spoilage.
00:05:38
And then another note was to possibly consider a higher salt
00:05:43
ratio. It should help the ferments to
00:05:46
store for longer, but keep in mind it's also going to make
00:05:48
them taste a little bit saltier too, so you know this is
00:05:51
something that you can play with.
00:05:53
It seems like a lot of these recommendations are a little
00:05:56
loosey goosey when it comes to fermentation, so long as you're
00:06:00
keeping things under the brine. Then it's all generally regarded
00:06:04
as being safe. You just have to keep an eye out
00:06:06
for you know the mold and stuff and and your temperature seems
00:06:10
to be the key component here. Everything else seems to be
00:06:13
well. You can play with it a little
00:06:15
bit. Thanks for joining me on this
00:06:17
focal point Friday. I'll be back again on Tuesday
00:06:20
for another regular. Episode of the Just Gross
00:06:22
Something podcast. So until next time, my gardening
00:06:24
friends, keep on cultivating that dream garden and we'll talk
00:06:27
again soon.
