How To Store Plums
At room temperature, you can store unripe plums on the countertop or somewhere in the kitchen. Make sure to not leave them in direct sunlight or close to any other heat source.
If you want to speed up the ripening process of the plums, you can either put them with other fruits or simply put them in a brown bag by themselves.
Other fruits such as apples and bananas produce a chemical known as ethylene. This chemical will speed up the ripening process. If plums are placed with these fruits, the plums will quickly ripen. Place them in a paper brown bag or in a basket and set them on the countertop.
The other option would be simply to put all the unripe plums in a paper brown bag. Close the bag so that no air can escape. The plums will start to release ethylene and the chemicals will cause the plums to ripen faster.
Once the plums are riped, it’s recommended to store them in the refrigerator to help slow down the ripening of the fruit.
However, if you want to store riped plums at room temperature, make sure to eat it within a couple of days. Otherwise, the plums will start to go bad quickly.
In the fridge, riped plums should be stored in a sealable plastic bag or an airtight container. You can either store them whole or slice them into smaller pieces.
You can either store them on the fridge’s shelf or in the crisper drawer. Either place is fine for storing plums. Most importantly, keep the plastic bag or container sealed and away from any smelly food products.
Can You Freeze Plums?
Plums are great are freezing and they actually freeze very well too. When freezing plums, make sure they are riped first before storing them in the freezer. If not, you’ll get the bitter taste when it defrosts.
In order to keep plums fresh for a long time in the freezer, you’ll need to prep them first. Simply just putting them in the freezer together will become a big mess when you thaw them.
Instead, use the flash freezing method before storing the plums in the freezer.
After the plums are riped, start by washing them to remove any dirt and pests that may be on the fruit. With a sharp knife, cut the fruit in half. You can either halve them or cut them into smaller pieces.
On a clean sheet of wax paper, spread the plums on the sheet spacing them out so they don’t touch each other. Place them in the freezer for about 5-6 hours. Once it’s completely frozen, immediately transfer the plums to a freezer bag or an airtight container. Place the plums back in the freezer.
The plums will stay fresh for up to 6 months in the freezer. However, you’ll still be able to eat them after that, but the quality of the fruit will decrease.
How To Keep Plums Fresh Longer
When buying plums, you’ll want to buy the one that’s the freshest. However, it can be hard to tell how fresh they are since plums don’t have an expiration date on them. The only way is to tell if they are fresh is by looking for signs of freshness.
When buying plums, you’ll want to buy ones that are unripened. This will give you time to keep them fresh longer at home. However, if you’re planning to eat them right away or in a couple of days, picking riped one is fine. Just make sure it’s not overly ripped.
The next thing to look for is blemishes and other signs of damage to the plums. There should be no cut or bruising on the outer skin of the fruit. A minor cut will cause the fruit to go bad before it ripened completely.
Besides the grocery stores, the farmer’s market is another excellent place to buy plums. At the farmer’s market, plums are usually fresh. Most sellers will pick the fruit the day before or on the day that it’s being sold.
When buying the plums, like at the grocery stores, you’ll want to examine the quality of it as well. Look for blemishes and other signs of damages on the skin of the fruit.
By choosing plums that are fresh and have no damages to them, this will ensure the fruit will stay fresh for a long time.
Due to their soft outer skin, plums can get damaged easily. This is especially true for riped plums. Light pressure on the plum could break the skin open. When it does, you’ll either need to eat them right away or they will start to go bad quickly.
When storing plums, never keep more than ten plums or more together in the same basket or container. As they continue to ripen, the ones on the bottom will start to get damaged by the pressure of the others on top.
What can I do with really ripe plums?
If you find yourself with plums that are really riped, it won’t taste very good due to their mushy texture. However, instead of throwing them away, you can make jam, sauce, cake, and desserts with riped plums.
