What is the difference between regular lime juice and key lime juice?
Regular lime juice and key lime juice differ in several ways, primarily due to the distinct characteristics of the limes they are derived from. Key limes are smaller, rounder, and have a thinner, more fragile skin than regular limes. They also have a more intense, acidic flavor and a stronger aroma. Regular limes, on the other hand, are larger, more oval in shape, and have a thicker, easier-to-zest skin. Their flavor is generally milder and less acidic than key limes.
These differences in flavor and acidity can significantly impact the taste and character of dishes that use lime juice as an ingredient. Key lime juice is often preferred in recipes that require a bold, tangy flavor, such as key lime pie, while regular lime juice may be more suitable for dishes that need a milder lime flavor.
Can I use regular lime juice as a substitute for key lime juice in recipes?
While it is technically possible to use regular lime juice as a substitute for key lime juice in recipes, it is not always the best option. Regular lime juice lacks the intense, acidic flavor and aroma of key lime juice, which can alter the character of the dish. However, if you don’t have access to key limes or prefer the milder flavor of regular limes, you can use regular lime juice as a substitute in some recipes.
When substituting regular lime juice for key lime juice, keep in mind that you may need to adjust the amount used and other ingredients in the recipe to achieve the desired flavor. Start with a smaller amount of regular lime juice and taste as you go, adding more if needed. You may also need to add other ingredients, such as sugar or spices, to balance out the flavor.
What are some recipes where I can safely substitute regular lime juice for key lime juice?
There are some recipes where you can safely substitute regular lime juice for key lime juice without significantly affecting the flavor or character of the dish. These include recipes where lime juice is used in small amounts or as a background flavor, such as in salad dressings, marinades, or sauces. You can also use regular lime juice in recipes where the flavor will be masked by other ingredients, such as in smoothies or desserts with strong flavors.
Some specific recipes where you can substitute regular lime juice for key lime juice include guacamole, salsa, and Thai-inspired dishes like tom yum soup or green curry. However, if you’re making a traditional key lime pie or other desserts that rely on the unique flavor of key limes, it’s best to use key lime juice for the best results.

How do I make key lime juice if I only have regular limes?
If you only have regular limes and want to make a substitute for key lime juice, you can try mixing regular lime juice with other ingredients to approximate the flavor.

Bottled key lime juice may contain preservatives or other additives that can affect the flavor, and it may not be as acidic or intense as freshly squeezed key lime juice. However, it can still be a good option if you’re short on time or prefer the convenience of a bottled product.
How do I store key lime juice to preserve its flavor and aroma?
