WHAT IS KEY LIME?
Key lime is popular variety of lime, a hybrid of some of the most ancient citrus fruits, mainly the citron, mandarin, orange and pomelo. It is also famously known for being the ‘Key’ to the Key Lime Pie! Key limes originated in Southeast Asia and were brought over by Spanish explorers to Florida, where they were naturalised. The tropical islands of Florida Keys gave this little yellow lime its name, and also gave the world the Key Lime Pie.
DIFFERENCES BETWEEN KEY LIME AND REGULAR LIME
The most commonly found limes are often the Persian lime variety, and there’s more than meets the eye when it comes to the differences between these and key limes. Can you spot a key lime from a Persian lime? Here are some things to look out for:
- firstly the size: key limes are smaller than regular – Persian – limes
- the rind: key limes have a thin, leathery skin that is yellow when ripe
- flavour profile: key limes have a bolder, slightly herbal-floral aroma, and are more acidic than Persian limes
- the inside: key limes have more seeds than regular limes
