What are Key Limes?
Key limes, also known as Mexican limes or West Indian limes, are a type of small citrus fruit. They are typically about the size of a golf ball, with a thin, smooth, greenish-yellow skin and a high acidity level. Key limes are known for their distinct tart flavor and aromatic qualities, which make them popular for use in cooking and baking, particularly in desserts like Key lime pie. They are native to Southeast Asia but are now cultivated in various tropical and subtropical regions around the world.
Are key limes different than regular limes?
Yes, key limes are different from regular limes in several ways:
- Size: Key limes are smaller in size compared to regular limes. They are typically about 1 to 2 inches in diameter, whereas regular limes are larger, often around 2 to 3 inches in diameter.
- Color: Key limes are usually yellowish-green when ripe, with a thinner, smoother skin compared to the thicker, rougher skin of regular limes. However, they may also have a slightly orange tint when fully ripe. Regular limes are generally bright green when ripe.
- Flavor: Key limes have a more complex and intense flavor compared to regular limes. They are known for their unique tartness and aromatic qualities. The flavor of key limes is often described as more floral and slightly sweeter than that of regular limes.
- Acidity: Key limes tend to be more acidic than regular limes, which contributes to their distinctive tart flavor. This higher acidity level is one reason why they are favored in certain culinary applications, such as in Key lime pie.
While both key limes and regular limes can be used in cooking and baking, they may impart slightly different flavors to dishes due to their distinct characteristics.

Do you need to refrigerate Key Lime Pie Bars?
Yes, it’s generally recommended to refrigerate key lime pie bars, especially if they contain perishable ingredients like eggs or dairy (such as condensed milk or cream cheese). Refrigeration helps to preserve the freshness and prevent the growth of bacteria, ensuring that the bars remain safe to eat for a longer period.
Additionally, refrigeration can help the bars maintain their texture and prevent them from becoming too soft or mushy, particularly in warmer climates or during hot weather.
Before serving, you can allow the key lime pie bars to come to room temperature for a few minutes if desired, as this can enhance their flavor and make them easier to slice. However, it’s important to return any leftovers to the refrigerator promptly to maintain their quality and safety.

Why won’t my graham cracker crust hold together?
There could be several reasons why your graham cracker crust isn’t holding together:
- Not Enough Binder: The binder in a graham cracker crust typically comes from melted butter or another fat. If you didn’t use enough butter or fat, the crumbs won’t stick together well enough to form a cohesive crust.
- Not Enough Pressure: When pressing the crust into the pan, make sure you apply enough pressure to compact the crumbs tightly. Using the bottom of a flat measuring cup or glass can help ensure even pressure.
- Crushed Graham Crackers Too Coarse: If the graham crackers are crushed too coarsely, the crumbs may not stick together properly. Aim for a fine, even texture when crushing the crackers.
- Underbaking: If you bake the crust for too short a time, the butter won’t have a chance to fully bind the crumbs together. Make sure to bake the crust according to the recipe instructions until it’s golden brown and set.
- Overbaking: Conversely, if you bake the crust for too long, the butter can melt out of the crumbs, causing the crust to become crumbly. Keep an eye on the crust while it bakes to prevent overbaking.
- Not Chilling the Crust: After pressing the crust into the pan, it’s important to chill it in the refrigerator for at least 30 minutes before adding the filling. This helps the crust firm up and hold its shape.

Thanks for pointing that out! I updated the recipe to include that. You add it into the filling during the mixing process.
