Plums, with their juicy flesh and vibrant colors, are a quintessential summer fruit. But their season is fleeting. What if you could capture that sun-ripened goodness and enjoy it throughout the year? The answer lies in the magic of freezing. And the question often arises: can you blanch and freeze plums? The short answer is yes, you can! But there’s more to it than just tossing them in the freezer. This comprehensive guide will walk you through the process, ensuring your frozen plums retain their flavor and texture, ready to be enjoyed in pies, jams, smoothies, or simply as a refreshing snack.
Why Freeze Plums? The Benefits of Preserving Your Harvest
Freezing is an excellent method for preserving fruits like plums. It halts enzymatic activity, which is responsible for degradation, and prevents the growth of microorganisms that cause spoilage. This allows you to enjoy the taste of summer long after the season has passed. But why freeze plums specifically?
Freezing extends the shelf life of plums significantly. Fresh plums last only a week or two in the refrigerator, but frozen plums can last for 8-12 months in the freezer, or even longer if properly stored. This allows you to stock up when plums are in season and at their peak ripeness and affordability.
Having a stash of frozen plums on hand opens up a world of culinary possibilities. From warm plum crumbles on a cold winter evening to vibrant plum smoothies on a hot summer day, frozen plums are a versatile ingredient that can be used in a variety of dishes. You can also use them to make plum jam, plum sauce, or even plum wine.
If you’re a gardener or have access to a local orchard, freezing allows you to preserve your bounty and avoid waste. Instead of letting excess plums rot on the tree or go bad in the fridge, you can freeze them and enjoy them throughout the year. This is a sustainable way to enjoy seasonal produce.
Blanching Plums: Is it Necessary?
Blanching, the process of briefly cooking fruits or vegetables in boiling water or steam, is often recommended before freezing. But when it comes to plums, is it a crucial step? The answer depends on your preferences and how you plan to use the frozen plums.
Blanching deactivates enzymes that can cause changes in color, flavor, and texture during freezing. While plums don’t brown as quickly as some other fruits, blanching can help preserve their bright color and prevent them from becoming mushy. This is especially important if you plan to use the plums in dishes where appearance is important, such as pies or tarts.
Unblanched plums tend to lose their firm texture and become softer after freezing. Blanching helps to set the pectin in the fruit, which contributes to its structure. If you prefer a firmer texture in your frozen plums, blanching is recommended.
While blanching offers benefits, it’s not strictly necessary. If you plan to use the plums in smoothies, jams, or sauces, where texture is less important, you can skip the blanching step. Some people also prefer the slightly more intense flavor of unblanched plums.
Ultimately, the decision of whether or not to blanch is a matter of personal preference. Consider how you plan to use the frozen plums and weigh the benefits of blanching against the extra effort.
Preparing Plums for Freezing: A Step-by-Step Guide
Whether you choose to blanch or not, proper preparation is key to ensuring the best quality frozen plums. Here’s a step-by-step guide to help you prepare your plums for freezing:
Start with ripe, but not overripe, plums. They should be firm to the touch and have a vibrant color. Avoid plums with bruises, blemishes, or soft spots.
Wash the plums thoroughly under cold running water to remove any dirt or debris. Gently rub the skin to ensure they are clean.
Remove the pits from the plums. You can do this by slicing the plums in half and using a small knife or spoon to remove the pit. Alternatively, you can use a cherry pitter.
If you’re blanching, bring a large pot of water to a rolling boil. Prepare an ice bath by filling a large bowl with ice and water.
Submerge the plums in the boiling water for 1-2 minutes. The exact time will depend on the size and ripeness of the plums. You want to heat them through, but not cook them completely.
Immediately transfer the blanched plums to the ice bath to stop the cooking process. Let them cool completely.
Whether you blanched the plums or not, pat them dry with a clean towel or paper towels. This will help prevent ice crystals from forming during freezing.
Lay the plum halves on a baking sheet lined with parchment paper or a silicone mat. Make sure the plums are not touching each other to prevent them from sticking together during freezing.
Place the baking sheet in the freezer and freeze the plums for at least 2 hours, or until they are solid. This is called flash freezing and it helps to prevent the plums from clumping together in the freezer bag.
Once the plums are frozen solid, transfer them to freezer-safe bags or containers. Remove as much air as possible from the bags to prevent freezer burn.
Label the bags or containers with the date and contents. This will help you keep track of how long the plums have been in the freezer.
Store the frozen plums in the freezer at 0°F (-18°C) or lower. Properly frozen plums can last for 8-12 months, or even longer.
Freezing Plums Without Blanching: A Quicker Method
If you’re short on time or prefer a more straightforward approach, you can freeze plums without blanching. The process is similar, but skips the blanching step.
Follow steps 1-3 of the preparation process: Select ripe plums, wash them thoroughly, and remove the pits.
Pat the plum halves dry with a clean towel or paper towels. This is especially important when freezing without blanching, as excess moisture can lead to ice crystal formation.
Follow steps 6-9 of the preparation process: Lay the plum halves on a baking sheet, flash freeze them, transfer them to freezer-safe bags or containers, and label them with the date and contents.
Remember that unblanched plums may lose their firm texture and become softer after freezing. They may also develop a slightly more intense flavor. However, they are still perfectly safe and delicious to eat.

Troubleshooting Common Freezing Problems
Sometimes, despite your best efforts, things can go wrong when freezing plums. Here are some common problems and how to avoid them:
Freezer burn occurs when frozen food is exposed to air. It causes the food to dry out and develop a leathery texture. To prevent freezer burn, make sure to remove as much air as possible from the freezer bags or containers. You can also wrap the plums tightly in plastic wrap before freezing.
Ice crystals can form on frozen plums if they are not properly dried before freezing. To prevent ice crystals, pat the plums dry with a clean towel or paper towels before freezing. You can also flash freeze them on a baking sheet before transferring them to freezer bags or containers.
If your frozen plums are mushy after thawing, it could be due to several factors. Overripe plums, improper blanching, or slow thawing can all contribute to a mushy texture. To avoid mushy plums, choose ripe but firm plums, blanch them briefly in boiling water, and thaw them slowly in the refrigerator.
If your frozen plums have lost their flavor, it could be due to improper storage. Frozen food can absorb odors from the freezer, which can affect its flavor. To prevent flavor loss, store the plums in airtight containers and avoid storing them near strong-smelling foods.
Conclusion: Enjoying the Taste of Summer Year-Round

Whether you choose to blanch them or not, following the steps outlined in this guide will help you achieve the best results. With a little bit of preparation, you can have a stash of frozen plums on hand for pies, jams, smoothies, and more. So, go ahead and stock up on plums during their peak season and enjoy the taste of summer all year round! Freezing is the best way to preserve the sweetness of plums.
Why should I blanch plums before freezing?
Blanching plums before freezing helps to preserve their quality, color, and texture. The brief heat treatment deactivates enzymes that cause degradation during frozen storage, preventing discoloration, softening, and off-flavors. This process essentially “pauses” the ripening process, ensuring the plums retain more of their fresh, vibrant characteristics.
Furthermore, blanching can also help to loosen the plum skin, making it easier to peel after thawing if desired. This is particularly helpful if you plan to use the plums in recipes where a smooth texture is important, such as jams, sauces, or purees. While not strictly necessary, blanching significantly improves the overall quality of frozen plums.
How long should I blanch plums for freezing?
The ideal blanching time for plums depends on their size and ripeness. Generally, a blanching time of 1 to 2 minutes is sufficient for small to medium-sized plums. Larger, more ripe plums might benefit from a slightly longer blanching time, closer to 2 minutes. It’s important to avoid over-blanching, as this can cause the plums to become mushy.
To ensure even blanching, place the plums in a pot of boiling water, ensuring they are fully submerged. After the recommended time, immediately transfer them to a bowl of ice water to stop the cooking process. This rapid cooling is crucial for preserving the plums’ texture and preventing them from becoming overcooked.
Can I freeze plums without blanching them first?
Yes, you can freeze plums without blanching, but be aware that their quality will likely be diminished compared to blanched plums. Without blanching, the enzymes responsible for degradation remain active, leading to changes in color, texture, and flavor over time in the freezer. The plums may become softer, develop a dull appearance, and lose some of their sweetness.
If you choose to skip blanching, it’s recommended to use the frozen plums within a shorter timeframe, ideally within a few months, to minimize the effects of enzyme activity. Freezing them quickly and storing them at a consistent, low temperature can also help to mitigate some of the quality loss. However, for the best results, blanching is always recommended.
What is the best way to freeze plums after blanching?
After blanching and thoroughly cooling the plums in ice water, the next step is to properly dry them. Gently pat the plums dry with a clean towel to remove any excess moisture. This helps prevent ice crystals from forming on the surface during freezing, which can lead to freezer burn and a less appealing texture.
Next, arrange the dried plums in a single layer on a baking sheet lined with parchment paper and freeze them for a few hours, or until solid. This process, called “flash freezing,” prevents the plums from clumping together in the freezer bag. Once frozen, transfer the plums to freezer-safe bags or containers, removing as much air as possible before sealing. Label the bags with the date and contents for easy identification.
How long can I store blanched and frozen plums?
When properly blanched and frozen, plums can be stored in the freezer for approximately 8 to 12 months while maintaining good quality. After this time, they will still be safe to eat, but their texture, flavor, and nutritional value may begin to decline. Maintaining a consistent freezer temperature of 0°F (-18°C) or lower is essential for optimal preservation.
To maximize the storage life of your frozen plums, ensure they are properly sealed in airtight containers or freezer bags to prevent freezer burn. Regularly check your freezer temperature and avoid opening the freezer door frequently, as fluctuations in temperature can accelerate degradation. Using the plums within the recommended timeframe will ensure the best possible eating experience.
How do I thaw frozen plums?
There are several ways to thaw frozen plums, depending on your intended use. The simplest method is to transfer the desired amount of plums from the freezer to the refrigerator and allow them to thaw slowly overnight. This gentle thawing process helps to preserve their texture and flavor.
For quicker thawing, you can place the sealed bag of plums in a bowl of cold water. Change the water every 30 minutes to maintain a cold temperature and speed up the thawing process. Alternatively, you can thaw the plums in the microwave using the defrost setting, but be cautious as this method can easily overcook them and result in a mushy texture. Thawed plums are best used immediately and should not be refrozen.
