Cherries, those delightful little bursts of summer flavor, are a highly anticipated treat. However, sometimes you might find yourself with cherries that aren’t quite ripe enough after picking them, whether from your own tree or purchased from a store. The big question is: can you ripen cherries after picking them, and if so, how? Let’s dive into the intricacies of cherry ripening and explore effective methods to achieve that perfect sweet and juicy bite.
Understanding Cherry Ripening: Before and After the Pick
The journey to a perfectly ripe cherry is complex. Cherries undergo a fascinating transformation as they mature on the tree, but that process unfortunately slows dramatically, and almost stops, once they are detached from their source of life.
The On-Tree Ripening Process
Before we delve into post-picking ripening, it’s essential to understand what happens while the cherry is still attached to the tree. During this stage, the fruit receives essential nutrients, sugars, and moisture directly from the tree. Sunlight plays a crucial role, converting starches into sugars, which contribute to the cherry’s sweetness. As the cherry ripens, it also develops its characteristic color, aroma, and texture. Ripening is a dynamic process involving enzymatic changes and hormonal signaling, none of which can be fully replicated after the fruit is picked.
Why Cherries Don’t Truly Ripen Off the Tree
Unlike some fruits like bananas or avocados, cherries are considered non-climacteric fruits. This means they do not produce a significant amount of ethylene gas, the hormone responsible for ripening in climacteric fruits, after being harvested. While you might observe some changes in color and softening, these are primarily due to dehydration and changes in the cell structure, not a continuation of the true ripening process. The sugar content, the key to a sweet cherry, will not increase significantly after picking. They might get a little softer and appear redder, but they won’t become substantially sweeter.
What You Can Expect After Picking: Managing Expectations
It’s crucial to have realistic expectations when it comes to “ripening” cherries after picking. You can improve their texture and appearance to some extent, making them more palatable, but you can’t magically transform an unripe cherry into a perfectly sweet one.
Color Change: An Illusion of Ripening
You’ll likely notice that green or light-colored cherries will gradually turn redder after being picked. This is due to the breakdown of chlorophyll and the increased visibility of underlying pigments. However, this color change doesn’t necessarily indicate sweetness. A dark red cherry might still be sour if it wasn’t sufficiently ripe when picked.
Softening: A Sign of Degradation
Cherries will soften after being picked, but this is often a sign of degradation rather than ripening. As the cells break down, the cherry loses its crispness and can become mushy. This softening can make the cherry easier to eat, but it doesn’t improve its flavor.
Limited Sugar Increase: A Harsh Reality
The amount of sugar in a cherry is largely determined by its maturity on the tree. While there might be a slight increase in sweetness due to water loss concentrating the existing sugars, it won’t be a dramatic change. Don’t expect a sour cherry to become noticeably sweet after being picked.
Techniques to Improve Cherries After Picking: Making the Best of It
While you can’t fully ripen cherries after picking, you can employ certain techniques to enhance their quality and make them more enjoyable. These methods primarily focus on preventing further degradation and improving their overall appearance and texture.
Proper Storage: The Key to Preservation
Proper storage is crucial to prevent spoilage and maintain the quality of your cherries.
- Refrigeration: Store cherries in the refrigerator immediately after picking or purchasing them. The cold temperature slows down the degradation process. Place them in a shallow container lined with paper towels to absorb excess moisture.
- Ventilation: Avoid storing cherries in airtight containers, as this can trap moisture and promote mold growth. Use containers with ventilation holes or loosely cover the container with plastic wrap.
- Avoid Washing Before Storage: Only wash cherries right before you plan to eat them. Washing them beforehand can introduce excess moisture and accelerate spoilage.
Ethylene Exposure: A Limited Effect
Although cherries are non-climacteric fruits, exposing them to ethylene gas might have a subtle effect on their color and texture. You can try placing cherries near ethylene-producing fruits like bananas or apples. However, don’t expect a significant change in sweetness. The ethylene exposure is more likely to influence skin color and softening.
Sunlight Exposure: A Delicate Balance
Some believe that exposing cherries to sunlight after picking can help them ripen. While sunlight is essential for ripening on the tree, it can also cause dehydration and damage to picked cherries. If you choose to try this method, do so with caution and for a limited time. Place the cherries in a single layer in a cool, shaded area with indirect sunlight. Monitor them closely to prevent them from overheating or drying out.
Using Cherries in Recipes: Transforming Sourness
If your cherries are too sour to eat fresh, consider using them in recipes that can mask or complement their tartness.
- Cooking and Baking: Cherries can be cooked into jams, pies, sauces, and other desserts. The cooking process can soften the cherries and mellow out their tartness. Adding sugar or other sweeteners can further enhance their flavor.
- Cherry Juice and Smoothies: Blend cherries into juice or smoothies to add a burst of flavor and nutrients. Combining them with sweeter fruits like bananas or mangoes can balance out the tartness.
- Savory Dishes: Don’t limit cherries to sweet dishes. They can also be used in savory recipes, such as sauces for meat or poultry. Their tartness can provide a unique and complementary flavor.
Sugar Syrups and Infusions: Sweetening the Deal
Another option is to infuse the cherries in sugar syrups or alcoholic beverages. This will not “ripen” them, but it can make them much more palatable.
- Cherry Syrup: A simple sugar syrup can be made by boiling water and sugar until dissolved. Add the cherries to the syrup and let them steep for several hours or overnight. This will draw out some of their flavor and infuse them with sweetness.
- Cherry Liqueur: Cherries can be infused in alcoholic beverages like brandy or vodka to create homemade liqueurs. The alcohol will extract the cherries’ flavor and aroma, creating a delicious and flavorful drink.
Preventing Unripe Cherries: Harvesting at the Right Time
The best way to ensure sweet and juicy cherries is to harvest them at the right stage of maturity. This requires careful observation and a bit of experience.
Visual Cues: Look for the Right Color
The color of a cherry is a good indicator of its ripeness. Different varieties have different color ranges, but generally, a fully ripe cherry will have a deep, rich color that is characteristic of the variety. Avoid picking cherries that are still green or light-colored.
Texture and Firmness: A Gentle Squeeze
Gently squeeze the cherry to assess its firmness. A ripe cherry will be slightly firm but not rock hard. Avoid picking cherries that are too soft or mushy, as they are likely overripe.
Taste Test: The Ultimate Indicator
The best way to determine if a cherry is ripe is to taste it. Pick a few cherries from different parts of the tree and give them a try. If they are sweet and juicy, it’s likely that the rest of the cherries are ripe as well.
Stem Condition: A Sign of Maturity
The stem of a ripe cherry should be easy to detach from the tree. If you have to tug or twist the cherry to remove it, it’s likely not fully ripe.
Conclusion: Enjoying Your Cherries, Ripe or Not
While you can’t truly ripen cherries after picking, you can take steps to improve their quality and make them more enjoyable. Proper storage, ethylene exposure (with caution), and creative culinary applications can help you make the most of your cherries, even if they’re not perfectly ripe. However, the key to truly delicious cherries is to harvest them at the right time, paying attention to visual cues, texture, and, of course, taste. So, whether you’re enjoying them fresh, baked into a pie, or blended into a smoothie, savor the delightful flavor of cherries and appreciate the efforts of nature. Focus on preventing spoilage and leveraging their tartness rather than expecting a miracle ripening process. Choose wisely, store carefully, and enjoy!
Why do cherries sometimes not ripen fully on the tree?
Several factors can prevent cherries from fully ripening on the tree. Common causes include insufficient sunlight exposure, particularly if the tree is heavily shaded by other trees or structures. Nutrient deficiencies in the soil can also hinder the ripening process, as cherries require specific nutrients like potassium and phosphorus for proper development and sugar production. Additionally, environmental stressors such as extreme heat or cold spells, or even heavy rainfall close to harvest time, can impact the ripening cycle.
Pest and disease infestations can significantly affect cherry ripening. Cherry leaf spot, for example, can cause premature leaf drop, depriving the fruit of essential energy for ripening. Similarly, infestations of pests like cherry fruit flies can damage the fruit and prevent it from reaching its full potential. These issues can sometimes be addressed with proper tree care, including pruning for sunlight, soil amendments, and pest/disease control measures.
Can cherries ripen after being picked?
Unfortunately, cherries are considered a non-climacteric fruit, meaning they do not continue to ripen significantly after being harvested. Unlike fruits like bananas or avocados, cherries don’t produce a burst of ethylene gas, which is the natural hormone that triggers ripening in climacteric fruits. Once picked, the sugar content and color may slightly deepen, but the overall sweetness and flavor will not drastically improve.
While cherries won’t become significantly sweeter after picking, proper storage can help preserve their quality and prevent spoilage. Keeping them cool and dry is crucial. Immediately refrigerating cherries after harvest will slow down the degradation process and maintain their firmness and appearance for a longer period. However, it’s essential to remember that refrigeration won’t make them riper, only help them retain their existing state.
What storage conditions are best for keeping freshly picked cherries?
The ideal storage conditions for freshly picked cherries involve maintaining a cool and humid environment. Immediately after harvesting, place cherries in the refrigerator at a temperature between 32°F and 36°F (0°C and 2°C). Store them in a container that allows for some air circulation to prevent moisture buildup and mold growth. A perforated plastic bag or a container with a slightly ajar lid is a good choice.
To further enhance preservation, consider lining the container with a paper towel to absorb excess moisture. Avoid washing cherries until just before you’re ready to eat them, as excess moisture can accelerate spoilage. Properly stored cherries can typically last for up to a week in the refrigerator, maintaining their quality and flavor.
How can I tell if cherries are truly unripe before picking?
Determining the ripeness of cherries before picking involves observing several key characteristics. The most obvious indicator is the color of the fruit. Ripe cherries will have a deep, rich color that is characteristic of their variety – whether it’s a deep red, mahogany, or even yellow. Look for a consistent and vibrant hue across the entire fruit, avoiding any with green or pale patches, which indicates under-ripeness.
Beyond color, gently feel the cherries. Ripe cherries will have a slightly firm but yielding texture when lightly squeezed. They shouldn’t be rock-hard, which suggests they’re not yet ripe, nor should they be overly soft or mushy, which indicates they might be overripe or damaged. Finally, taste one or two cherries from different parts of the tree to gauge their sweetness. If they lack sweetness and have a tart or acidic flavor, they likely need more time to ripen on the tree.
Is there anything I can do to make unripe cherries more palatable?
While you can’t truly ripen cherries after picking, there are a few culinary techniques that can make unripe cherries more palatable. The most effective method is to cook them. Cooking softens the fruit and concentrates the natural sugars, making them sweeter and more flavorful. Using them in pies, jams, sauces, or even compotes can transform their tartness into a pleasant taste.
Another approach is to pair the unripe cherries with sweeter ingredients. For example, adding them to a smoothie with bananas, honey, or other sweet fruits can help balance out the tartness. You can also try macerating them in sugar or a sweet liqueur for a few hours or overnight, which will draw out some of their moisture and infuse them with sweetness.
What are the common mistakes to avoid when handling freshly picked cherries?
Several common mistakes can shorten the shelf life and diminish the quality of freshly picked cherries. One of the biggest mistakes is leaving cherries at room temperature for extended periods, especially in warm weather. This accelerates their respiration rate, leading to faster spoilage and loss of flavor. Always refrigerate cherries as soon as possible after picking.
Another frequent error is washing cherries before storing them. The added moisture can create a breeding ground for mold and bacteria, causing them to rot more quickly. Only wash cherries right before you plan to eat them. Additionally, avoid packing cherries too tightly in containers, as this can bruise them and promote spoilage. Ensure there’s adequate air circulation around the fruit.
Are there any cherry varieties that ripen better after being picked than others?
In general, the ability of cherries to ripen after being picked is minimal across all varieties, as they are non-climacteric fruits. While some varieties might exhibit a very slight deepening in color or a subtle softening of texture after harvest, this is more a result of natural degradation than true ripening. The inherent characteristics of the variety, such as sugar content and acidity, are largely fixed at the time of picking.
That being said, certain varieties known for their higher sugar content to begin with, such as Bing or Rainier cherries, might be perceived as being slightly more palatable even when not fully ripe compared to tarter varieties like Montmorency. However, this is due to their inherent sweetness rather than an increased ability to ripen off the tree. It’s always best to pick cherries when they are as close to fully ripe as possible on the tree for the best flavor and texture.
