Now that I’ve been canning for some 20 years, I like instructing it to different folks. Nonetheless, the USDA learns new issues yearly, and as such, canning guidelines often change. A few of these modifications within the final 10 years have made canning much more environment friendly and far much less painful. (I’ve additionally obtained my very own hacks, which I am going to share right here.)
Canning makes meals shelf-stable
At a primary stage, canning is exposing cooked meals to pressurized warmth for a protracted sufficient time, at sufficient stress, to kill any pathogens, seal the jars and make the meals shelf-stable. Now, you may’t simply can something. Meals should have a sure acidity to be secure, and be ready in a particular method to stop harmful micro organism from cultivating in your jars. Moreover, it’s important to use particular jars meant for canning. There are nonetheless a handful of botulism circumstances yearly, and it’s a wildly painful and typically lethal infliction. The USDA and Ball (the corporate that produces most canning provides, and a canning authority) each produce secure recipes to observe when you’re beginning out. There’s specialised tools like stress canners which can be vital to securely course of some meals. Tomatoes may be processed at a decrease temperature and stress, so that you don’t want a stress canner for these. However canned tuna and different acidic merchandise require the stress canner.
No extra pre-sterilizing jars and lids
It was that along with cooking the jam or sauce going into the jars, you had to spend so much of time prepping the jars: sterilizing them, dealing with the recent jars, after which sterilizing the lids. All of this dealing with sizzling metallic and glass meant further time and hazard. Newer laws, nonetheless, provide you with some leeway. The USDA now says you don’t have to sterilize jars if you will be processing them for longer than 10 minutes. Since I’ve but to discover a single recipe that requires lower than 10 minutes of processing, you may clear your jars properly (a dishwasher is ideal for this) and use them immediately.
In additional excellent news, Ball, the maker of most jars and lids, determined in 2014 that it was not suggested to boil lids earlier than use. As soon as meals is in your jars, use clear fingers to put a lid on the jar, after which seal with the canning ring.
Can within the dimension jar you’ll use
Most recipes and footage present all the pieces canned in quart dimension jars. A quart is a lot, except you’ve gotten a household. When you’re canning for one or two, don’t be afraid to make use of smaller-size jars. Annually, I can my tomato sauce in smaller and smaller jars, as a result of that’s how a lot I take advantage of for a meal for one. I can my pickles in half pints, as a result of if I’m making burgers, I would like simply sufficient pickles for that, with out having to retailer a complete jar in my fridge after. Jars are available one million sizes, so think twice about what you’ll actually use. Don’t can ketchup in a pint dimension, as an example—you gained’t use it quick sufficient. Identical for jam.
You possibly can sous vide your pickles
As I discussed earlier, totally different meals have totally different wants for processing. Some meals want a stress canner, however low-acid meals like pickles can merely be processed utilizing boiling water in a big canning pot. Nonetheless, it is a lot of sizzling water and warmth and glass. Lesley Kinzel wrote about sous vide canning for pickles a number of years in the past and now it’s the solely technique I take advantage of. It’s gentler on the pickles themselves, leading to higher crunch; it additionally means much less sizzling water and fewer warmth within the kitchen, all whereas assembly all the necessities for processing.
Label, label, label
You suppose you’ll keep in mind what’s in a jar, however I promise you, you gained’t. All jam appears the identical. All tomato merchandise look the identical. You additionally need the date on every jar, since most jars have a two-year shelf life. I simply write on the lids, which aren’t reusable, with a Sharpie. However when you’re in search of a nicer presentation, think about dissolvable labels. Some other form of label is depressing to get off your jars. However I do suppose you employ ought to common labels, too, for one goal: Make small labels along with your title on them and affix them to the underside of your jars. That is your assurance you’ll get your jars again once you inevitably present them away.
Be sure you’re storing cans the proper approach
A part of canning is storing these jars the proper approach, since you want the lids to remain sealed. So typically I see folks stacking jars, which is an absolute no-no. There are two issues you could keep in mind: First, take away the canning ring earlier than storage. This may occasionally appear counterintuitive, however the jars are absolutely sealed with the lid (and in the event that they didn’t absolutely seal, they must be used instantly or the contents tossed). Leaving the ring on might provide you with false confidence in a lid that has popped by concealing that it’s occurred. So, take away the rings earlier than storage; they’re meant to be reused time and again. Second, when stacking jars, you have to put one thing between them, like cardboard. The bins that jars are available are excellent for this, which is why most individuals maintain onto them, and use them for storage.
The idea of sous vide canning for pickles is fascinating! It seems like a modern twist on traditional methods, and I’m curious about how it impacts flavor and texture compared to boiling water processing.
This article provides a comprehensive overview of modern canning techniques. I appreciate the emphasis on safety and the updates to guidelines, especially for those new to canning. It makes the process seem more approachable.
I completely agree with the need for proper labeling. It’s easy to forget what’s inside jars after some time, and keeping track of dates is essential for ensuring food safety in long-term storage.
I found the section on jar sizes quite enlightening. Many people might not consider how jar dimensions affect their cooking habits. Using smaller jars for individual meals seems like a practical approach for many home cooks.
It’s interesting to see how canning practices have evolved over the years. The tip about not needing to sterilize jars for longer processes is particularly useful, as it saves time and effort in the kitchen.
