Selection and Storage
When purchasing jackfruit, it is essential to determine the intended use, as this influences both selection and the appropriate storage method. Fresh jackfruit requires different handling than canned or frozen options.
Choosing the Right Jackfruit
For those who seek ripe jackfruit for its sweet flavor, one should look for fruit that has a vibrant yellow color and a fragrant, sweet smell. The outer skin should give slightly under pressure. Conversely, unripe jackfruit should possess a firmer skin and a green color, indicative of its starchy texture and suitability for savory dishes.
Canned jackfruit is often available in brine or syrup and is a convenient option, though the texture and taste can differ from fresh jackfruit.
Frozen jackfruit can be a good alternative, retaining much of the texture and flavor of the fresh fruit while offering a longer shelf life.
Preservation Techniques
To preserve the quality of fresh jackfruit after purchase:
Rinse the whole fruit under cold water to remove any external residue.
Store whole ripe jackfruit at room temperature for 2-3 days or in the refrigerator for up to 5-7 days.
For cut jackfruit, remove the seeds and store the flesh in an airtight container in the refrigerator to extend its shelf life.
Submerging cut pieces in a water solution with added lemon juice or vinegar can help prevent browning.
Raw jackfruit's shelf life can be extended by wrapping it in plastic or aluminum foil before refrigerating to maintain its firmness and prevent odor absorption.
For longer storage, freezing is suitable for cut jackfruit. Place the pieces on a baking sheet to freeze individually, then transfer them into a freezer-safe bag, squeezing out excess air before sealing. Frozen jackfruit can last for several months. If one opts for canned jackfruit, it should be stored in a cool, dry place and, once opened, transferred to a non-metallic container and refrigerated, to be used within a few days.
Preparation and Usage
Preparing unripe jackfruit properly can ensure it's safe to eat and enjoyable, offering a variety of recipe options from savory dishes to tropical-inspired smoothies.
Preparing Unripe Jackfruit
To prepare unripe jackfruit, one must start by wearing plastic or rubber gloves to avoid the sticky sap. The outer skin is hard and green, and it should be discarded. Cut the jackfruit into two-inch slices and then halve these pieces. Using a paring knife, the core should be separated from the fruit pods, which can then be removed along with the white fibers and tips. After cutting the pods in half lengthwise, remove the seeds and their rubbery skins. The unripe flesh of jackfruit is quite starchy, akin to plantains, and can be boiled, fried, or roasted for various recipes.
Creative Recipe Ideas
When it comes to incorporating unripe jackfruit into recipes, its texture makes it a versatile ingredient.
Unripe Jackfruit Tacos: Similar to pulled pork, the cooked flesh can be shredded and seasoned with spices for a meat-free taco filling.
Jackfruit Curry: The starchy component can be added to curries, much like adding potatoes or mangoes for a sweet and savory balance.
Tropical Jackfruit Smoothie: Though typically used when ripe, an inventive use of unripe jackfruit is to blend it into a smoothie with bananas and pineapple for an exotic twist.
Jackfruit Stir-Fry: Pair with vegetables and a savory sauce for a hearty stir-fry.
One can experiment with jackfruit as they would with other starchy foods in their cooking, enhancing the flavor profile of traditional dishes or creating new ones.
