Ever come across a key lime and often get confused on whether its a key lime or just a regular lime? Have you often wondered what properties key limes have that make them differ from limes?

Well, here’s the thing – key limes differ significantly from limes. So, what is the difference between a key lime and a lime?

Key Limes are smaller than regular limes – and with seeds. If you take your thumb and connect it to your first finger to make a circle, that is about the size of a key lime – approximately about 20mm in circumference. A regular lime on the other hand is a little bigger, 30mm in circumference and without seeds.

While key limes are smaller and have seeds, limes on the other hand, are bigger and usually, without seeds.

This is just the main difference between them, however, there are several other differences as you’ll get to learn in this guide.

Although, key limes are more popularly known for the famous Florida dessert – the Key Lime Pie, that isn’t all there is it to this wonderful alkaline citrus fruit.

Key limes are unarguably one of the most alkalizing fruits there is. This amazing fruit can be used in a variety of recipes including desserts, and alkaline water. They add a zesty flavor to dishes, can be used as alkaline dressings and rubs, or even used as deodorants.

Key lime is smaller

If you put a key lime right beside a regular lime, the most prominent difference you’ll quickly notice is in the size. This difference is quite noticeable as key limes are smaller than their lime counterparts. Infact, key limes are almost half the size of limes, but typically not more than 3 quarters.

While Key limes are typically the size of a table tennis ball, Persian or regular limes are just a little bigger, almost one diameter in size compared to key limes that are just about half or three quarters diameter.

Key lime is more rounded

Key limes are often rounded in shape and with a smoother skin on them. While Regular limes are a bit oblong in shape. While regular limes have a thick bright green skin, that of key lime is thinner. key limes vs limes

When unripe, limes are vividly green and key limes dark green. When ripe, limes become yellow, and key limes turn yellowish-green.

Regular limes are heavier as well, weighing in at more than three and half ounces, three times more than key limes that weigh averagely one ounce. Limes also have a more mottled appearance than key limes.

Key Lime is more tangy

Key Limes have a bit more tangy-sweet taste compared to limes, and so, their inclusion in recipes makes it more on the sweet side of the tangy-sweet spectrum.

Key Lime is more aromatic

Key lime has a stronger, more intense and aromatic taste than lime. Key limes have a stronger aromatic flavor than regular limes, although they can be quite close.

Key limes are well known for their unique aroma that brings a lot of a unique, zesty and tangy flavor to dishes, desserts, and beverages.

It’s strong aromatic flavor is an understandable reason it is used in making natural alkaline Deodorants which are a natural odorizer against body does and unpleasant smells.

The aroma from key limes is also longer-lasting as they often last up to 48 hours on a surface, even after washing.

Key limes are more natural

Key limes grow in the Florida Keys and the Caribbean. Regular or “Persian” limes are Asian in origin. Regular Limes are a hybrid of yellow lemons and key limes. Regular limes are seedless, and going by what Dr. Sebi says about seedless foods, they are unnatural and have little or no nutrition.

Regular limes are hybrid, unnatural and hence have incomplete chemical structure. Many of the missing health benefits in normal limes are found in key limes, which are the more natural alternative.

Key Limes are harder to find

Persian limes and lime juice are available in grocery stores all year. It can be difficult to find fresh key limes because they’re in shorter supply and don’t stay fresh as long. However, bottled or premade key lime juice is available in specialty and online stores.

Key limes are preferred to limes in cooking and garnishing because it’s strong aroma diffuses through ingredients in a dish and this can make a whole lot of difference between a smoothie that’s plain sweet or tarty or bland and one that brings a sweet-tangy twist to its profile.

Key limes are more beneficial

Key limes are commonly used for dish preparation and garnishing including sauces, rubs, desserts, dressings, beverages, drinks, or marinades. 

Key limes trees are smaller

Just like the fruits they produce, key lime trees are stout and small, you can almost compare them to a high shrub. They often do not grow more than 6 to 13 feet, and would rather grow or branch out laterally than vertically.

Key lime tree leaves are smaller, a bit darker with rounded edges. The trees also have quite a lot of sturdy thorns which makes harvesting the fruits sometimes a nightmare.

Regular lime trees on the other hand grow taller, often more than 15 to 20 feet.

They branch out more vertically than laterally, with brighter green leaves that are oblong and serrated. The trees also have hardly any thorns.

Key Limes are Grown Rarely

Key Lime trees are largely grown in Florida, California and Mexico. While Regular Lime trees grow in Asian countries of China, India as well as parts of South America such as Brazil and Argentina.
