Cherries, those jewel-toned fruits bursting with sweetness and a hint of tartness, are a summer delight. But what happens when you pick them – or buy them – and they’re not quite ready to eat? Can you coax them into full ripeness off the tree? The answer is a bit more complex than a simple yes or no. Let’s delve into the world of cherries and explore the factors that influence their ripening process, both on and off the tree.
Understanding Cherry Ripening: The Basics
Cherry ripening is a delicate dance of sugars, acids, and pigments. On the tree, the fruit receives nutrients and energy from the parent plant, allowing it to develop its characteristic color, flavor, and texture. This process is driven by sunlight, temperature, and the tree’s overall health. As the cherry matures, starches convert into sugars, acids decrease, and pigments called anthocyanins accumulate, giving the fruit its deep red or black hue.
The key to successful ripening is understanding that once a cherry is picked, it no longer receives nourishment from the tree. This means the processes that rely on the tree’s resources – namely, the production of more sugars – effectively stop.
The Role of Ethylene in Cherry Ripening
Ethylene, often referred to as the “ripening hormone,” plays a significant role in the maturation of many fruits. It triggers a cascade of biochemical changes that lead to softening, color development, and aroma production. However, cherries are considered non-climacteric fruits. This means they produce very little ethylene after being harvested, and their ripening process is largely dependent on what has already occurred while they are still attached to the tree. While ethylene might influence some softening, it won’t significantly increase sugar content.
Visual Clues: Gauging Cherry Maturity
Before we even consider post-harvest ripening, it’s essential to assess the cherries’ initial state. Color is a primary indicator. Look for a deep, even color throughout the fruit. For sweet cherries, this usually means a deep red to almost black hue, depending on the variety. Rainier cherries should have a vibrant yellow base with a red blush. Sour cherries will be bright red when ripe.
Also, feel the cherries. They should be firm but yield slightly to gentle pressure. Overly hard cherries are likely underripe, while mushy ones are overripe. The stem should be green and pliable, indicating recent harvesting. A dry, brittle stem suggests the cherries have been stored for a while.
Can You Actually Ripen Cherries After Picking? The Reality
Here’s the crux of the matter: you can’t truly ripen cherries off the tree in the same way you can with climacteric fruits like bananas or tomatoes. These fruits continue to produce ethylene and undergo significant changes after harvest. Cherries, being non-climacteric, have limited capacity for further sugar development.
However, all hope is not lost. While you can’t make a completely unripe cherry sweet, you can potentially improve its texture and allow some existing sugars to become more prominent.
What You *Can* Do: Softening and Flavor Enhancement
The limited changes you can achieve after picking primarily involve softening and a slight perceived increase in sweetness. This is due to the breakdown of complex carbohydrates into simpler sugars that were already present in the cherry. It’s more of a flavor enhancement rather than a significant increase in sweetness.
Factors Affecting Post-Harvest Changes
Several factors can influence the limited ripening that can occur off the tree:
- Initial Maturity: Cherries that are close to ripe when picked have the best chance of improving in flavor and texture. Completely unripe cherries will likely remain tart and hard.
- Temperature: Warmer temperatures can accelerate the softening process, but they also increase the risk of spoilage. Cool temperatures slow down any changes.
- Humidity: Maintaining a slightly humid environment can help prevent the cherries from drying out.
- Storage Conditions: Avoid storing cherries in direct sunlight or near ethylene-producing fruits like bananas or apples, as this can hasten deterioration.
Methods for “Ripening” Cherries: Tips and Techniques
Given the limitations, the goal is not to make a cherry ripe but rather to allow it to express its existing potential.
The Countertop Method: A Gentle Approach
This is the simplest method. Spread the cherries in a single layer on a plate or tray lined with paper towels. Keep them at room temperature, away from direct sunlight. Check them daily for softening and any signs of spoilage. This method works best for cherries that are already close to ripe.
Paper Bag Method: For Slightly Firmer Cherries
Place the cherries in a paper bag and loosely fold the top. This creates a slightly enclosed environment that can help trap any ethylene produced and promote softening. Again, monitor them closely for spoilage.
Refrigerator Storage: Extending Shelf Life (with Caution)
While refrigeration won’t ripen cherries, it can slow down the ripening process and extend their shelf life. Store the cherries in a perforated plastic bag in the crisper drawer of your refrigerator. This helps maintain humidity while allowing for air circulation. Be aware that refrigeration can sometimes dull the flavor, so it’s best to bring the cherries to room temperature before eating.
Beyond Ripening: Making the Most of Underripe Cherries
If you find yourself with a batch of cherries that are simply too tart, don’t despair! There are many ways to use them, even if you can’t make them perfectly sweet for fresh eating.
Cooking and Baking: Transforming Tartness into Deliciousness
Underripe cherries are excellent for cooking and baking. The heat softens them and brings out their flavor, and you can adjust the sweetness with sugar or other sweeteners. Consider making:
- Cherry pie or cobbler
- Cherry jam or preserves
- Cherry sauce for meat or poultry
- Cherry-filled pastries
Freezing Cherries: Preserving for Later Use
Freezing is a great way to preserve cherries for future use. Wash and pit the cherries, then spread them in a single layer on a baking sheet lined with parchment paper. Freeze for a few hours until solid, then transfer them to a freezer bag or container. Frozen cherries are perfect for smoothies, baking, or making sauces.
Choosing Cherries: A Guide to Picking the Best
The best way to ensure you have delicious cherries is to choose them carefully in the first place.
- Look for plump, shiny cherries with a deep, even color. Avoid any that are bruised, shriveled, or have blemishes.
- Check the stems. They should be green and firmly attached.
- Smell the cherries. They should have a fresh, slightly sweet aroma.
- Buy from a reputable source. Farmers markets and local orchards often offer the freshest and highest-quality cherries.
Conclusion: Cherries – A Labor of Love, Best Enjoyed Ripe
While you can’t magically transform an unripe cherry into a perfectly sweet one after picking, understanding the factors involved can help you maximize their potential. Focus on selecting cherries that are already close to ripe, store them properly, and consider alternative uses for those that remain too tart. With a little care and creativity, you can enjoy the unique flavor of cherries in all their forms. Remember, the journey from tree to table is a crucial part of the cherry experience, and enjoying them at their peak ripeness is the ultimate reward.
Can cherries be ripened after they’ve been picked from the tree?
Unfortunately, unlike some fruits like bananas or avocados, cherries do not continue to ripen significantly after they’ve been harvested. This is because cherries, being non-climacteric fruits, require a connection to the tree for the ripening process to complete. Once picked, they lack the necessary hormonal and nutrient supply to undergo the chemical changes needed to become sweeter and more flavorful.
While the color of a cherry might deepen slightly after picking, this is primarily due to dehydration and not true ripening. The sugar content will not increase, and the texture will not improve. Therefore, it’s crucial to pick cherries when they are fully ripe on the tree to ensure the best flavor and texture.
What happens if I pick cherries that are not fully ripe?
Picking cherries before they are fully ripe will result in a fruit that is tart, firm, and lacking the characteristic sweetness of a ripe cherry. The color may be a pale red or even pink, indicating that the fruit has not reached its full potential. The texture will be noticeably less juicy and more astringent.
Because cherries don’t ripen off the tree, these unripe cherries will remain tart and firm even if left at room temperature. They will eventually spoil, but they will not sweeten or become more palatable. It’s best to wait until the cherries are fully colored and slightly soft to the touch before harvesting to avoid disappointment.
How can I tell if a cherry is ripe and ready to be picked?
The best indicator of ripeness is the color of the cherry. The specific shade will depend on the variety, but generally, a fully ripe cherry will have a deep, rich, and uniform color. For example, Bing cherries should be a dark, almost black-red, while Rainier cherries should have a vibrant yellow base with a red blush.
Another way to assess ripeness is by gently touching the cherry. A ripe cherry will yield slightly to gentle pressure. Also, consider the ease with which the cherry detaches from the stem. A ripe cherry will come off the tree relatively easily with a gentle tug, leaving the stem attached to the fruit.
Are there any tricks to make picked cherries taste better if they are slightly underripe?
Since cherries won’t ripen after picking, there aren’t any methods to make them significantly sweeter. However, you can try using them in cooked applications where the tartness is balanced by other flavors. For instance, underripe cherries can be used in pies, jams, or sauces where added sugar can compensate for their lack of sweetness.
Another option is to marinate them. Soaking slightly underripe cherries in a mixture of sugar, vinegar, and spices can help to soften them and create a more complex flavor profile. This approach won’t make them as sweet as fully ripe cherries, but it can make them more palatable and suitable for specific recipes.
How should I store cherries after picking to preserve their quality?
The best way to store cherries after picking is to keep them refrigerated. Place them in a shallow container or bag, preferably unwashed, to prevent moisture buildup which can lead to mold. Excess moisture accelerates spoilage, so maintaining a dry environment is crucial.
Cherries stored properly in the refrigerator can typically last for up to a week. Avoid storing them at room temperature, as this will cause them to deteriorate much faster. When you’re ready to eat them, wash them gently under cool water just before consumption to preserve their freshness and flavor.
What causes cherries to spoil after being picked?
Cherries spoil after picking due to a combination of factors, primarily moisture loss and microbial growth. As cherries sit, they lose moisture, which can cause them to shrivel and become less appealing. This dehydration also affects their texture, making them less juicy and plump.
Furthermore, cherries are susceptible to mold and bacterial growth, especially in warm and humid conditions. These microorganisms thrive on the natural sugars present in the fruit, leading to decay. Proper storage, as described above, helps to slow down these processes and extend the shelf life of the picked cherries.
Can I freeze cherries to preserve them for later use?
Yes, freezing cherries is an excellent way to preserve them for later use. Before freezing, wash and pit the cherries. Pitting them beforehand makes them easier to use in recipes later on. You can use a cherry pitter or a knife to remove the pits.
After pitting, lay the cherries out in a single layer on a baking sheet and freeze them for a few hours. This prevents them from clumping together into a solid mass. Once frozen solid, transfer the cherries to a freezer bag or airtight container. Properly frozen cherries can last for up to a year and are perfect for use in smoothies, pies, or other baked goods.
