Key Limes
What it is
Key limes are a variety of lime known for their distinct tartness and aromatic zest. They are smaller and more seedy than Persian limes, which are commonly found in grocery stores. Their intense flavor makes them a favorite for many culinary applications. The thin skin also contributes to their unique profile, releasing a fragrant oil when zested.
How people cook with it
These small citrus fruits are prized for their intense flavor in both sweet and savory dishes. They add a bright, zesty note that can elevate many recipes.
- Zesting for desserts
- Juicing for marinades
- Flavoring beverages
- Adding tang to sauces
To use key limes, begin by washing them thoroughly. For their juice, cut them in half and squeeze using a citrus press or by hand. Be aware that they contain more seeds than other lime varieties, so straining the juice is often recommended. The zest can be carefully removed with a microplane or fine grater, avoiding the bitter white pith. The zest adds a fragrant oil and concentrated lime essence to baked goods, dressings, and marinades. The juice is essential for classic desserts and can be used to brighten up seafood and poultry.
How it differs from similar foods
Key limes are significantly more tart and aromatic than the larger, more common Persian limes. Their smaller size and thinner rind mean they yield a more concentrated flavor. This intensity makes them ideal when a powerful lime taste is desired, whereas Persian limes offer a milder citrus note.
Who it is for
Home cooks and professional chefs who appreciate a more intense citrus flavor often choose key limes.
How to keep the rest
To store fresh key limes, keep them at room temperature for a few days or refrigerate them in a plastic bag for up to two weeks. For longer storage, you can freeze the juice in ice cube trays or zest and freeze the rinds separately.
