Plums and nectarines should be peeled, as their skins can be tough / chewy in jam. If you do want to leave the skins in, you might want to run the fruit through a blender or food processor to chop them up (after you remove the pits, of course). The skins will easily slide off now IF the plums are ripe!
Did you know you can steam can your fruits, jams, jellies and pickles in your Instant Pot? Steam canning in your Instant Pot is a great way to preserve smaller batches of food as it takes less water, less overall time to process, and doesn't heat up your entire kitchen!
What's the difference between plum butter and plum jam, you might be wondering? While jam is typically made of cooked fruit with the addition of pectin to make it somewhat gelatinous, fruit butter is basically a reduced fruit puree. Fruit butters are usually silkier, more spreadable, and use waaaay less sugar. More reading: red pepper jelly epicurious.
Or, you can also buy commercial pectin to add into jam recipes to help them gel. Personally, I don't like to mess with it, so I went about making my plum jam without pectin! Some fruits are higher in pectin than others and work better in no pectin jam recipes. Luckily, plums are one of those high-pectin fruits! Dig more about plum jam or preserves.

The skin is edible, but if you want raw plums without the skin, drop into into boiling water for around 15 seconds, then plunge immediately into cold water and it should come away easily. If you're cooking plums, they're easier to skin afterwards.
You can use it to keep all sorts of low-acid foods preserved. In short, you can put a Mason jar inside of a pressure cooker without facing any problems, although it can also depend on the jar in question. Make sure that the type of jar you're using is of high quality. Good to read: chicken thighs fillet recipe.
Instant Pots are equipped to sterilise any household glass, silicone, and dishwasher safe plastics. You can either use the sterilise function available on newer models of the Instant Pot or pressure cook/steam for a short period of time on those without. We also wrote chicken thighs slow cooker recipes.
Instant pots are not tested for canning.A jar can be sealed by simply sitting in a hot grocery store shelf, completely empty, and we know that's not a safe canning process, right? The seal is only ONE part of the very important trifecta of elements that works to ensure water bath canning is safe.
A delicious fruit jam, known as plum butter, to spread on warm bread, toast or scones. You can also use it to sandwich a sponge cake. A lovely way to preserve the flavour of local plums for enjoyment year-round.
There are a few differences between fruit butter and jam: Jam is typically sweeter. Fruit butter often contains sweetener but can be made sugar-free, whereas jams rely on lots of sugar to preserve the original fruit's color and texture. Fruit butter is smoother.
Fig butter has a rich, sweet flavor. Since it's made with less sugar than fig jam, it has a creamier consistency and more of a rustic, hearty texture. You can make fig jam with absolutely no added sugar, but a little honey, some cardamom, and a pinch of salt round out the flavor profile.
Pectin can reduce the body's ability to absorb beta-carotene, an important nutrient. And pectin can also interfere with the body's ability to absorb certain drugs, including: Digoxin (a heart medicine) Lovastatin (a cholesterol-lowering drug)
The sliced freezing method is great for storing frozen plums for an extended period of time, but one of our favorite summer hacks is freezing our plums whole. All you need to do is wash the plums and place the whole fruits in a plastic bag in the freezer. Plums aren't the only fresh produce we're freezing.
Add pectin.Whisk a tablespoon of powdered pectin (preferably the no-sugar-needed variety) into the pot of cooking jam. Test for thickness and add another tablespoon if needed.
you can die from eating too much of everything, but AFAIK plums are not inherently dangerous. Plums and prunes are known for their laxative effect. It is important to keep in mind that eating too many prunes at once may lead to undesirable effects, such as diarrhea.
Plum might cause stomach issues like gas and diarrhea. If dried plums or pits are swallowed whole, they might block the movement of food through the stomach and intestines. Some people are allergic to plums.
Wash ripe plums.The better they taste before you freeze them, the better they'll taste when you thaw them. Rinse the plums under cool water to remove any dirt or debris. If the plums are still a little green, ripen them on your counter for a few days before freezing them.
Fresh plums do not have much fiber, but dried plums – prunes – have as many as 12 g fiber per cup and are excellent for relieving constipation.
