Here’s a breakdown of limes vs lemons: the difference between these popular citrus fruits and when to use each one in cooking!
I keep a bright blue bowl on my counter full of lemons and limes, which I use almost daily in my kitchen. Squeezing one or the other over a dish is probably my most-used recipe hack.
As a cookbook author, here’s what I’ve learned about these two citrus fruits, from flavor and nutrition to exactly when to use each one. Lime vs lemon: what’s the difference in flavor and acidity, and can you substitute one for the other? Here’s an overview of the differences and similarities, and the culinary uses for each.
Lemons vs Limes
First, let’s discuss the definition of each of these citrus fruits! What’s the difference between a lemon and a lime? Limes and lemons are different fruits, but closely related.
- Limes are small, round green citrus fruits with an acidic, sour flavor. There are several species of limes: the Key lime, Persian lime, makrut lime, and desert lime. Most limes you’ll find at the grocery store are Persian limes. Limes are often used in Mexican, Latin-American and Southeast Asian cuisine.
- Lemons are oval-shaped yellow citrus fruits with a tart flavor. Lemons are often used in Mediterranean and European cuisine. The type of lemon in most grocery stores in North America are either Eureka or Lisbon. The Meyer lemon is also available: it’s a cross between a lemon and a Mandarin orange.
Main Nutritional Differences
Limes and lemons are very similar nutritionally. Here are a few of the similarities and differences of limes vs lemons:
Different Culinary Uses For Lemons and Limes
Can lime be used instead of lemon? Can lemon be used instead of lime? Sometimes! Both citrus fruits have a tart flavor that adds a zing and brightness to recipes. They often work as substitutes for each other, but not always. It goes without saying that you can’t make key lime pie with lemons, or limeade with lemons. Here are some pointers for substitution:
- Lime juice can be a good substitute for lemon juice. But keep in mind: lime has a strong connotation with Latin or Southeast Asian flavors, whereas lemon is mostly Mediterranean. It wouldn’t make sense to add a squeeze of lime juice to your lasagna or arugula salad. Be sure to think about the flavors of your dishes to see what makes sense.
- Lemon juice can be a good substitute for lime juice. But keep in mind: lime is a key flavor in Latin and Mexican cuisine. Lemon can work as a stand-in, but nothing can fully replace lime in a margarita or salsa fresca.
Frequently Asked Questions
No! While they’re both citrus fruits and close botanical relatives, limes and lemons are distinct species with different flavors, colors, and culinary uses. And no, a lemon is not a ripe lime, despite the popular myth.
Lemons contain slightly more citric acid, but many people perceive limes as tasting sharper because of their bitter notes. In practice, they’re similarly sour — the difference is in the aromatic flavors surrounding that sourness.
In a sense, most citrus is! Nearly all modern citrus fruits are hybrids of a few ancestral species. Lemons are believed to be a natural cross between citron and bitter orange, and the common Persian lime is a hybrid as well.
