It is also possible for them to remain in good condition for up to two months if stored correctly in a sealed container or plastic bag to retain moisture and prevent overexposure to air.
Understanding Limes
Limes are a versatile citrus fruit, treasured for their tart flavor and aromatic zest. They belong to the same family as lemons and oranges, all of which are characterized by their high vitamin C content.
Key limes are small, aromatic, and known for their intense tartness.
Mexican limes, also known as Persian limes, are larger and milder.
Limes' bright green rind encases the juicy, acidic segments within. Their sourness distinguishes them from sweeter citrus relatives like oranges and apples, making limes a unique addition to culinary dishes and beverages.
Freshness Factors:
Texture: A fresh lime should feel firm. Soft spots could indicate spoilage.
Color: They are typically green, but some varieties may yellow with age while still being edible.
Smell: Fresh limes have a citrus scent. A foul odor signifies spoilage.
Unlike apples that can last several months, or oranges with a few weeks' longevity, limes have a comparatively shorter shelf life. To maximize freshness, storage is key. Room temperature is suitable for short-term, but refrigeration can extend their life.
