How to preserve plums?

Storing plums properly allows them to retain their juicy flesh, aroma, and characteristic balance of sweetness and acidity for longer. The best method depends primarily on the degree of ripeness of the fruit when purchased: plums that are still firm can ripen fully at room temperature, while those that are already soft and ready to eat are best stored in the refrigerator.

Storing all plums immediately in the refrigerator is therefore not always the best option. Low temperatures slow the ripening process and, in the case of unripe fruits, can prevent the full development of flavor and aroma. Before storing them, it's helpful to check their consistency, separate any damaged ones, and decide which ones to eat first.

How to recognize ripe plums

A ripe plum should be slightly soft when gently pressed, but not mushy or yielding. The peel should be intact, free of cuts, mold, deep bruises, or wet spots.

Color isn't always a reliable indicator, as different varieties can be green, yellow, red, blue, or purple even when they're perfectly ripe. It's therefore best to evaluate their texture and aroma first.

A thin, opaque, whitish layer may be present on the skin. This film, called bloom, is a natural protective coating produced by the fruit and should not be confused with mold. Its presence is normal and often indicates that the plum has been handled sparingly. It is easily removed by washing before eating.

Plums with small bruises can still be used, but should be separated from the other plums and consumed promptly. Those with a fermented odor, slimy flesh, or mold should be discarded.

How to preserve unripe plums

Plums that are still hard should be left at room temperature in a cool, dry place away from direct sunlight. They can be arranged in a basket or on a tray, avoiding stacking them in too many layers.

It's important not to place them near the oven, stove, radiators, or other heat-producing appliances. Too high a temperature can cause them to soften quickly and unevenly, compromising the texture of the flesh.

During this stage, it's advisable to check them daily. The time required for complete ripening varies depending on the variety, initial firmness, and room temperature.

To speed up the process, plums can be placed in a paper bag with a ripe apple, pear, or banana. These fruits release ethylene, a natural substance that promotes ripening. The bag does not need to be hermetically sealed and should be checked frequently.

It is preferable to avoid completely sealed plastic bags, as they can trap condensation and create an excessively humid environment.

How to store ripe plums in the refrigerator

Once the plums have reached the desired level of ripeness, they can be transferred to the refrigerator. The low temperatures slow down spoilage and help preserve their texture for several days.

The most suitable location is generally the crisper drawer. The fruit should be arranged without crushing it, preferably in a shallow container or a slightly open bag.

A sheet of paper towel placed on the bottom of the container can collect any moisture. However, it should be replaced if it becomes damp, as an overly humid environment encourages the growth of mold.

Ripe plums should be kept away from apples, pears, bananas, and other ethylene-producing fruits, as they may continue to soften too quickly even in the refrigerator.

Shelf life varies depending on initial conditions. Plums that are still fairly firm can be kept for several days, while those that are very soft should be consumed quickly.

Do you need to wash them before storing them?

Plums should not be washed before storing in the refrigerator. Water left on the skin can increase humidity and promote spoilage, especially if the fruit is kept in a container.

It's best to wash them under running water just before eating. After rinsing, they can be gently dried with paper towels or a clean dishcloth.

There's no need to use soap, detergents, vinegar, or baking soda. A thorough rinse under running water is sufficient for normal household cleaning.

How to store cut plums

A cut plum doesn't keep as long as a whole fruit. The flesh exposed to air tends to lose moisture, darken, and absorb odors present in the refrigerator.

Opened plums should be stored in an airtight container and refrigerated. They are best consumed within a day or two.

When using them in a fruit salad, salad, or dessert, it's best to cut them just before serving. A few drops of lemon juice can slow oxidation, but it should be added sparingly so as not to overpower the fruit's natural flavor.

Can plums be frozen?

Plums can be frozen, although the flesh will be softer and less crunchy after thawing. For this reason, they are especially suitable for jams, compotes, sauces, smoothies, cakes, and baked desserts.

Before freezing, they must be washed, dried, halved, and pitted. The segments can be arranged on a tray without overlapping and frozen separately.

Once they're solid, they can be transferred to a freezer-safe bag or container. This method prevents the pieces from sticking together and allows you to scoop out only the amount you need.

How to use very ripe plums

Plums that have become too soft to be eaten raw can still be salvaged, as long as they do not show mold, an unpleasant odor, or signs of fermentation.

They're ideal for making jams, compotes, crumbles, cakes, smoothies, and sweet and sour sauces. They can also be sautéed briefly in a pan with a little lemon juice and used to accompany yogurt, ricotta, or desserts.

In conclusion

Unripe plums should be left at room temperature until the flesh becomes slightly soft. Once ripe, they are best stored in the refrigerator, protected from impact and away from fruits that produce a lot of ethylene gas.

It's best not to wash them ahead of time, but to check them regularly and consume the softest ones first. Sliced ​​plums should be protected and used quickly, while freezing is a practical solution for preserving them and using them later in numerous sweet and savory dishes.
