Kamias, also known as bilimbi or tree cucumber, is a sour fruit widely used in Filipino cuisine. Its natural tartness and unique flavor profile make it a perfect candidate for pickling. The pickling process not only preserves the kamias but also enhances its flavor, transforming it into an indispensable condiment and side dish. In the Philippines, the methods vary from simple salted fermentation to sweet pickling with a balance of vinegar, sugar, and spices. This versatility allows kamias to be adapted to various tastes and culinary preferences.
The traditional approach, known as Burong Kamias, is a fermented method that draws out the natural juices of the fruit while developing a complex sour flavor. This process utilizes non-iodized sea salt to create a brine from the fruit’s own liquid.
For the fermented method, you will need fresh kamias, preferably light green, plump, and free from bruises. Non-iodized sea salt is essential, usually measured as about 5% of the total weight of the fruit. Before layering, clean the kamias thoroughly and remove any petals or stems. If desired, you can prick the fruits with a toothpick to help the brining process.
Begin by alternate layering the sliced or whole kamias with sea salt in a sterilized jar. It is recommended to start and finish with the fruit to ensure a balanced distribution. Close the jar tightly and store it in a cool, dry place. The fermentation period typically varies from a few days to two weeks, depending on ambient temperature and your desired level of sourness. Stir the jar gently every now and then to keep the kamias fully submerged in the brine, which helps prevent oxidation.
For those who prefer a sweeter profile, the sweet pickled version of kamias involves the creation of a hot pickling liquid. This method balances the natural sourness of the fruit with syrupy sweetness derived from sugar and vinegar.
Common ingredients include white vinegar, white sugar, water, and non-iodized sea salt. A typical ratio used is a 1:1 mix of vinegar and water, with sugar added to taste. Some recipes call for additional spices like red chili powder, black pepper, or turmeric to add layers of flavor.
The process starts with washing and drying the kamias, followed by pricking them with a toothpick to allow the hot pickling liquid to penetrate. In a saucepan, combine the vinegar, water, sugar, and salt; bring the mixture to a boil until the sugar is completely dissolved. Once the liquid is ready, carefully pour it over the packed kamias in a sterilized jar, ensuring the fruit is entirely covered. Seal the jar, allow it to cool, and then store in the refrigerator. The pickled kamias are usually ready to enjoy after sitting for at least an hour, though flavor intensifies with time.
Modern interpretations of pickled kamias often include creative variations that build on traditional techniques. Some recipes incorporate additional spices such as laurel leaves, asafoetida, and fenugreek powder for a nuanced taste profile. These methods maintain the essence of Filipino culinary heritage while appealing to contemporary palates.
Experimentation in pickling can also lead to interesting flavor dynamics. For example, combining the fermented method with a brief heating of a sweet pickling liquid creates a layered taste that is at once sour, salty, and sweet. Another variation might add a subtle smokiness by incorporating ingredients like char-grilled chili or even a hint of roasted garlic. Whether through fermentation or quick pickling, the aim is to preserve the fruit while enriching its taste for diverse culinary uses.
Beyond its pleasing flavor, kamias is packed with nutrients. The fruit is a good source of vitamin C, essential for boosting immunity, and also contains modest amounts of protein, iron, and calcium. The fermentation process can enhance the bioavailability of these nutrients, making pickled kamias not only a flavorful addition to your meals but also a potentially nutritious one.
Pickled kamias serves as an excellent condiment in various dishes. In Filipino cuisine, it is traditionally served alongside grilled or fried meats to provide a counterbalance to rich and savory flavors. Additionally, its sharp, tangy notes make it a perfect ingredient for soups, especially sinigang, a famous Filipino sour soup. The versatility of pickled kamias means it can also be chopped and added to salads, sandwiches, or rice dishes to bring a refreshing zing to the palate.

The initial step in the fermentation method is the application of non-iodized sea salt. Salt is critical not only for flavor but also for drawing out moisture from the fruit, creating a brine that discourages the growth of undesirable bacteria. This environment promotes the growth of naturally occurring lactic acid bacteria, which ferment the sugars present in the fruit and produce lactic acid. The lactic acid not only imparts a distinctive sour flavor but also acts as a natural preservative.
In the vinegar-based pickling method, the acid from the vinegar quickly penetrates the fruit, providing a different preservation mechanism. The addition of sugar serves to counterbalance the sharp acidity and sourness of the kamias, offering a smoother, more rounded flavor. Furthermore, the warm pickling liquid allows concentrations of flavors to meld rapidly, sealing in the intense aromas and tastes that have made pickled kamias a beloved ingredient in Filipino kitchens.
When preparing pickled kamias, it is essential to use sterilized jars and utensils to avoid contamination. Boiling the jars or using a sterilizer can greatly reduce the risk of harmful bacteria interfering with the fermentation or pickling process. Moreover, once the pickling process has been initiated—whether through fermentation or by using heated pickling liquid—the product should be stored in a cool environment. Refrigeration is highly recommended once the initial pickling period has passed, especially for sweet pickling methods, to maintain freshness and safety over time.
For optimal results, select kamias that are firm yet not overly ripe. The fruit should have a consistent light green hue and show no signs of blemishes. Fresh and high-quality kamias will yield the best flavors and ensure a successful pickling outcome, whether you are fermenting them or using a vinegar-based method.
Many home cooks in the Philippines have put a unique spin on traditional pickled kamias by introducing additional ingredients such as spicy red chili, aromatic turmeric, or a dash of asafoetida. These variations not only enhance the flavor profile but also provide a modern twist on a time-honored preservation method. Experimenting with proportions and additional spices can allow you to create a personalized version that perfectly complements your dietary preferences and culinary style.
The longevity of pickled kamias largely depends on the method used. Fermented kamias typically remain fresh for several weeks when stored in a cool, dark place, while adding a vinegar-based or sugar-sweetened pickling solution may extend their shelf life even further when refrigerated. Always ensure that the fruit remains completely submerged in the pickling liquid to avoid any exposure to air, which can compromise both safety and flavor.
