Speaking of peanut butter, your first thought might be sandwiches since this is its most popular and classic use. However, today we are not going to talking about its uses but preservation methods since many people argue that peanuts butter shouldn’t be frozen. So, is that true?
Why wouldn’t jam, ketchup, and peanut sauce sold in supermarkets easily go bad before the refrigerator was invented? That means they were generally left at room temperature for a few months. In fact, this is determined by its natural ingredients, including peanuts, cooking oil, sugar, salt and the like. That’s to say, as long as it is finished within 3 months, you don’t need to worry about the spoilage at all even though it is stored at room temperature. This might be the possible reason that makes you believe that you can’t freeze peanut butter. On the contrary, the truth is that you can freeze and defrost it again and again. So, do just as you please.
Although it has a very long shelf life, typically up to 1 year when the jar is unopened or 2 to 3 months opened, for some reason you still need to extend that period as long as possible. For example, in the opened case the oil stored in the butter will gradually break down, which will thereby cause change in quality and flavor. Such butter may be still considered safe to consume but it is not that appetizing to you anymore. In order to keep the flavor and texture as long as possible, apparently you should do something to inhibit the action of enzymes and bacteria that make peanut butter go bad. And at least you can try 5 methods as follows:
1. It should be stored in a cool, dry, and clean place. A lay of oil should be used atop to inhibit microbial growth by cutting off their air supply;
2. Add in a relatively large amount of salt or sugar;
3. Place the opened one into a pot, preferably a pressure cooker, and sterilize it by boiling very time after you use it;
4. Make sure to seal it immediately after each use;
5. After opened, it should be stored in a freezer, preferably set to 4.5 degrees Celsius. By doing so, the shelf life will be extended to 9 months.
As you can see now, if you can do any of the mentioned 5 methods you will greatly extend the shelf life. However, in comparison the freezing way is much simpler and more convenient.
What’s more, as an added bonus the frozen one can sometimes help you find more than you’d hoped for. For example, you can use it to make frozen peanut butter and jelly sandwiches, frozen balls, pie, dog treats, and so on. No doubt, these frozen snacks are good ideas for hot days that can make your life in summer just a little bit easier.
